EMISSION CONTROL INFORMATION To protect the environment in which we all live, Kawasaki has incorporated crankcase emission (1) and exhaust emission (2) control systems in compliance with applicable regulations of the United States Environmental Protection Agency and California Air Resources Board. Additionally, Kawasaki has incorporated an evaporative emission control system (3) in compliance with applicable regulations of the California Air Resources Board on vehicles sold in California only. 1. Crankcase Emission Control System This system eliminates the release of crankcase vapors into the atmosphere. Instead, the vapors are routed through an oil separator to the inlet side of the engine. While the engine is operating, the vapors are drawn into combustion chamber, where they are burned along with the fuel and air supplied by the fuel injection system. 2. Exhaust Emission Control System This system reduces the amount of pollutants discharged into the atmosphere by the exhaust of this motorcycle. The fuel, ignition, and exhaust systems of this motorcycle have been carefully designed and constructed to ensure an efficient engine with low exhaust pollutant levels. The exhaust system of this model motorcycle manufactured primarily for sale in California includes a catalytic converter system. 3. Evaporative Emission Control System Vapors caused by fuel evaporation in the fuel system are not vented into the atmosphere. Instead, fuel vapors are routed into the running engine to be burned, or stored in a canister when the engine is stopped. Liquid fuel is caught by a vapor separator and returned to the fuel tank. The Clean Air Act, which is the Federal law covering motor vehicle pollution, contains what is commonly referred to as the Act’s "tampering provisions." "Sec. 203(a) The following acts and the causing thereof are prohibited... (3)(A) for any person to remove or render inoperative any device or element of design installed on or in a motor vehicle or motor vehicle engine in compliance with regulations under this title prior to its sale and delivery to the ultimate purchaser, or for any manufacturer or dealer knowingly to remove or render inoperative any such device or element of design after such sale and delivery to the ultimate purchaser. (3)(B) for any person engaged in the business of repairing, servicing, selling, leasing, or trading motor vehicles or motor vehicle engines, or who operates a fleet of motor vehicles knowingly to remove or render inoperative any device or element of design installed on or in a motor vehicle or motor vehicle engine in compliance with regulations under this title following its sale and delivery to the ultimate purchaser..."

NOTE The phrase "remove or render inoperative any device or element of design" has been generally ○ interpreted as follows: 1. Tampering does not include the temporary removal or rendering inoperative of devices or elements of design in order to perform maintenance. 2. Tampering could include: a.Maladjustment of vehicle components such that the emission standards are exceeded. b.Use of replacement parts or accessories which adversely affect the performance or durability of the motorcycle. c.Addition of components or accessories that result in the vehicle exceeding the standards. d.Permanently removing, disconnecting, or rendering inoperative any component or element of design of the emission control systems. WE RECOMMEND THAT ALL DEALERS OBSERVE THESE PROVISIONS OF FEDERAL LAW, THE VIOLATION OF WHICH IS PUNISHABLE BY CIVIL PENALTIES NOT EXCEEDING $10,000 PER VIOLATION.

TAMPERING WITH NOISE CONTROL SYSTEM PROHIBITED Federal law prohibits the following acts or the causing thereof: (1) The removal or rendering inoperative by any person other than for purposes of maintenance, repair, or replacement, of any device or element of design incorporated into any new vehicle for the purpose of noise control prior to its sale or delivery to the ultimate purchaser or while it is in use, or (2) the use of the vehicle after such device or element of design has been removed or rendered inoperative by any person. Among those acts presumed to constitute tampering are the acts listed below: Replacement of the original exhaust system or muffler with a component not in compliance with Federal regulations. Removal of the muffler(s) or any internal portion of the muffler(s). Removal of the air box or air box cover. Modifications to the muffler(s) or air inlet system by cutting, drilling, or other means if such modifications result in increased noise levels.

In order to perform the work efficiently and to avoid costly mistakes, read the text, thoroughly familiarize yourself with the procedures before starting work, and then do the work carefully in a clean area. Whenever special tools or equipment are specified, do not use makeshift tools or equipment. Precision measurements can only be made if the proper instruments are used, and the use of substitute tools may adversely affect safe operation. For the duration of the warranty period, we recommend that all repairs and scheduled maintenance be performed in accordance with this service manual. Any owner maintenance or repair procedure not performed in accordance with this manual may void the warranty. To get the longest life out of your vehicle: Follow the Periodic Maintenance Chart in the Service Manual. Be alert for problems and non-scheduled maintenance. Use proper tools and genuine Kawasaki Motorcycle parts. Special tools, gauges, and testers that are necessary when servicing Kawasaki motorcycles are introduced by the Special Tool Catalog or Manual. Genuine parts provided as spare parts are listed in the Parts Catalog. Follow the procedures in this manual carefully. Don’t take shortcuts. Remember to keep complete records of maintenance and repair with dates and any new parts installed.

1-2 GENERAL INFORMATION Before Servicing Before starting to perform an inspection service or carry out a disassembly and reassembly operation on a motorcycle, read the precautions given below. To facilitate actual operations, notes, illustrations, photographs, cautions, and detailed descriptions have been included in each chapter wherever necessary. This section explains the items that require particular attention during the removal and reinstallation or disassembly and reassembly of general parts. Especially note the following:

Battery Ground Before completing any service on the motorcycle, disconnect the battery wires from the battery to prevent the engine from accidentally turning over. Disconnect the ground wire (–) first and then the positive (+). When completed with the service, first connect the positive (+) wire to the positive (+) terminal of the battery then the negative (–) wire to the negative terminal.

Edges of Parts Lift large or heavy parts wearing gloves to prevent injury from possible sharp edges on the parts.

Solvent Use a high-flush point solvent when cleaning parts. High -flush point solvent should be used according to directions of the solvent manufacturer.

Cleaning vehicle before disassembly Clean the vehicle thoroughly before disassembly. Dirt or other foreign materials entering into sealed areas during vehicle disassembly can cause excessive wear and decrease performance of the vehicle.

GENERAL INFORMATION 1-3 Before Servicing Arrangement and Cleaning of Removed Parts Disassembled parts are easy to confuse. Arrange the parts according to the order the parts were disassembled and clean the parts in order prior to assembly.

Storage of Removed Parts After all the parts including subassembly parts have been cleaned, store the parts in a clean area. Put a clean cloth or plastic sheet over the parts to protect from any foreign materials that may collect before re-assembly.

Inspection Reuse of worn or damaged parts may lead to serious accident. Visually inspect removed parts for corrosion, discoloration, or other damage. Refer to the appropriate sections of this manual for service limits on individual parts. Replace the parts if any damage has been found or if the part is beyond its service limit.

Replacement Parts Replacement Parts must be KAWASAKI genuine or recommended by KAWASAKI. Gaskets, O-rings, Oil seals, Grease seals, circlips or cotter pins must be replaced with new ones whenever disassembled.

Assembly Order In most cases assembly order is the reverse of disassembly, however, if assembly order is provided in this Service Manual, follow the procedures given.

1-4 GENERAL INFORMATION Before Servicing Tightening Sequence Generally, when installing a part with several bolts, nuts, or screws, start them all in their holes and tighten them to a snug fit. Then tighten them according to the specified sequence to prevent case warpage or deformation which can lead to malfunction. Conversely when loosening the bolts, nuts, or screws, first loosen all of them by about a quarter turn and then remove them. If the specified tightening sequence is not indicated, tighten the fasteners alternating diagonally.

Tightening Torque Incorrect torque applied to a bolt, nut, or screw may lead to serious damage. Tighten fasteners to the specified torque using a good quality torque wrench.

Force Use common sense during disassembly and assembly, excessive force can cause expensive or hard to repair damage. When necessary, remove screws that have a non -permanent locking agent applied using an impact driver. Use a plastic-faced mallet whenever tapping is necessary.

Gasket, O-ring Hardening, shrinkage, or damage of both gaskets and O-rings after disassembly can reduce sealing performance. Remove old gaskets and clean the sealing surfaces thoroughly so that no gasket material or other material remains. Install new gaskets and replace used O-rings when re-assembling

Liquid Gasket, Non-Permanent Locking Agent For applications that require Liquid Gasket or a Non-Permanent Locking agent, clean the surfaces so that no oil residue remains before applying liquid gasket or Non-Permanent locking agent. Do not apply them excessively. Excessive application can clog oil passages and cause serious damage.

GENERAL INFORMATION 1-5 Before Servicing Press For items such as bearings or oil seals that must be pressed into place, apply small amount of oil to the contact area. Be sure to maintain proper alignment and use smooth movements when installing.

Ball Bearing and Needle Bearing Do not remove pressed ball or needle unless removal is absolutely necessary. Replace with new ones whenever removed. Press bearings with the manufacturer and size marks facing out. Press the bearing into place by putting pressure on the correct bearing race as shown. Pressing the incorrect race can cause pressure between the inner and outer race and result in bearing damage.

Oil Seal, Grease Seal Do not remove pressed oil or grease seals unless removal is necessary. Replace with new ones whenever removed. Press new oil seals with manufacture and size marks facing out. Make sure the seal is aligned properly when installing.

Apply specified grease to the lip of seal before installing the seal.

Circlips, Cotter Pins Replace circlips or cotter pins that were removed with new ones. Take care not to open the clip excessively when installing to prevent deformation.

1-6 GENERAL INFORMATION Before Servicing Lubrication It is important to lubricate rotating or sliding parts during assembly to minimize wear during initial operation. Lubrication points are called out throughout this manual, apply the specific oil or grease as specified.

Direction of Engine Rotation When rotating the crankshaft by hand, the free play amount of rotating direction will affect the adjustment. Rotate the crankshaft to positive direction (clockwise viewed from output side).

Electrical Wires A two-color wire is identified first by the primary color and then the stripe color. Unless instructed otherwise, electrical wires must be connected to those of the same color.

Run the engine at the idle speed, and turn the handlebar all the way to the right and left to ensure that the idle speed doesn’t change. If the idle speed increases, check the throttle grip free play and the cable routing.

PERIODIC MAINTENANCE 2-17 Periodic Maintenance Procedures necessary, adjust the throttle cable as follows: •○IfLoosen the locknuts [A] and screw the adjusters [B] all the

way in so as to give the throttle grip plenty of play. ○Turn out the adjuster of the decelerator cable [C] until there is no play. ○Tighten the locknut against the adjuster. ○Turn the adjuster of the accelerator cable [D] until the proper amount of throttle grip free play is obtained and tighten the locknut against the adjuster.

(fast idle). ○Gradually the fast idle will lower to a certain RPM automatically. This is the idle speed. With the engine idling, turn the handlebar to both sides. If handlebar movement changes the idle speed, the throttle cables may be improperly adjusted or incorrectly routed or damaged. Be sure to correct any of these conditions before riding (see Cable, Wire, and Hose Routing section in the Appendix chapter).

WARNING Operation with improperly adjusted, incorrectly routed or damaged cables could result in an unsafe riding condition. the idle speed. • Check If the idle speed is out of the specified range, adjust it (see Idle Speed Adjustment in this chapter). Idle Speed Standard: 950 ±50 r/min (rpm)

2-18 PERIODIC MAINTENANCE Periodic Maintenance Procedures Choke Knob Operation

○Do not use the choke knob except when the engine has

a starting difficulty, like in cold weather (10°C or below) or at high altitude. The DFI system has an automatic choke system, using ISC valves, a water temperature sensor, and an atmospheric pressure sensor, which provide start ability.

NOTE

○Pull the choke knob [A] fully when using.

The choke lever [B] doesn’t work with the choke knob halfway.

Front [C] When flooded, do not crank the engine with the throt○ tle fully opened. This promotes engine flooding because more fuel is supplied automatically by the DFI system.

Fuel Hose Inspection (Fuel Leak, Damage, Installation Condition)

○The fuel hoses are designed to be used throughout the

• • •

motorcycle’s life without any maintenance, however, if the motorcycle is not properly handled, the high pressure inside the fuel line can cause fuel to leak [A] or the hose to burst. Remove the fuel tank (see Fuel Tank Removal in the Fuel System (DFI) chapter) and check the fuel hose. Replace the fuel hose if any fraying, cracks [B] or bulges [C] are noticed. Check that the hoses are securely connected and clamps are tightened correctly. When installing, route the hoses according to Cable, Wire, and Hose Routing section in the Appendix chapter. When installing the fuel hoses, avoid sharp bending, kinking, flattening or twisting, and route the fuel hoses with a minimum of bending so that the fuel flow will not be obstructed. Replace the hose if it has been sharply bent or kinked.

PERIODIC MAINTENANCE 2-19 Periodic Maintenance Procedures Cooling System Coolant Level Inspection NOTE

○Check the level when the engine is cold (room or ambient temperature).

the coolant level in the reserve tank with the motor• Check cycle held upright. The coolant level should be between the “F” (full) level and the “L” (low) level (In the photo, the right side cover has been removed for clarity). Front [A] Reserve Tank [B] “F” Level [C] “L” Level [D] If the coolant level is lower than the “L” level, remove the right side cover and the reserve tank cap, then add coolant to the ”F” level.

CAUTION For refilling, add the specified mixture of coolant and soft water. Adding water alone dilutes the coolant and degrades its anticorrosion properties. The diluted coolant can attack the aluminum engine parts. In an emergency, soft water can be added, but the diluted coolant must be returned to the correct mixture ratio within a few days. If coolant must be added often or the reserve tank has run completely dry, there is probably leakage in the cooling system. Check the system for leaks. Coolant ruins painted surfaces. Immediately wash away any coolant that spills on the frame, engine, wheels, or other painted parts.

Radiator Hose Inspection (Coolant Leak, Damage, Installation Condition)

○The high pressure inside the radiator hose can cause

coolant to leak [A] or the hose to burst if the line is not properly maintained. Visually inspect the hoses for signs of deterioration. Squeeze the hoses. A hose should not be hard and brittle, nor should it be soft or swollen. Replace the hose if any fraying, cracks [B] or bulges [C] are noticed. Check that the hoses are securely connected and clamps are tightened correctly. Torque - Water Hose Clamp Screws: 2.5 N·m (0.25 kgf·m, 22 in·lb)

○Remove the band [A] and take out the canister [B]. ○Visually inspect the canister for cracks and other damage.

If the canister has any cracks or bad damage, replace it with a new one.

NOTE

○The canister is designed to work well through the motor-

cycle’s life without any maintenance if it is used under normal conditions.

○Run

the purge hose (green) [A] above the canister breather hose (blue) [B] through the hole [C] into the tool case [D]. ○Do not run these hoses side by side on the battery side of the canister. This prevents hoses from being flattened when installing the left side cover. ○Install the canister and the left side cover (see Left Side Cover Installation in the Frame chapter). ○Face the white mark [E] left as shown. the liquid/vapor separator as follows: •○Check Disconnect the hoses from the separator, and remove the

FUEL SYSTEM (DFI) 3-21 DFI Servicing Precautions There are a number of important precautions that should be followed servicing the DFI system.

○To maintain the correct fuel-air mixture (F/A), there must

be no inlet air leaks in the DFI system. Be sure to install the oil filler cap [A] after filling the engine oil, using the filler cap driver [B]. Clutch Cover [C] Front [D] Special Tool - Filler Cap Driver: 57001-1454 Torque - Oil Filler Cap: 1.5 N·m (0.15 kgf·m, 13 in·lb)

○This DFI system is designed to be used with a 12 V sealed

battery as its power source. Do not use any other battery except for a 12 V sealed battery as a power source. ○Do not reverse the battery lead connections. This will damage the ECU. ○Do not disconnect the battery leads or any other electrical connections when the ignition switch is on, or while the engine is running. Otherwise, surge damages the connector terminals or the DFI parts. ○Take care not to short the leads that are directly connected to the battery positive (+) terminal to the chassis ground. ○When charging, remove the battery from the motorcycle. This is to prevent ECU damage by excessive voltage.

○Whenever the DFI electrical connections are to be dis-

connected, first turn off the ignition switch, and disconnect the battery (–) terminal. Do not pull the lead, only the connector. Conversely, make sure that all the DFI electrical connections are firmly reconnected before starting the engine. ○Connect these connectors until they click [A]. ○Do not turn the ignition switch ON while any of the DFI electrical connectors are disconnected. The ECU memorizes fault codes. ○Do not spray water on the electrical parts, DFI parts, connectors, leads, and wiring. Never water a vehicle with connectors unplugged because seals don’t work and terminals could corrode. ○To prevent corrosion and deposits in the fuel system, do not add any fuel antifreeze chemicals to fuel. ○When any fuel hose is disconnected, do not turn on the ignition switch. Otherwise, the fuel pump will operate and fuel will spout from the fuel hose. ○Do not operate the fuel pump if the pump is completely dry. This is to prevent pump seizure. ○Before removing the fuel system parts, blow the outer surfaces of these parts clean with compressed air. ○When any fuel hose is disconnected, fuel may spout out by residual pressure in the fuel line. Cover the hose joint with a piece of clean cloth to prevent fuel spillage.

3-22 FUEL SYSTEM (DFI) Troubleshooting the DFI System Outline When an abnormality in the system occurs, the FI indicator LED light [A] and FI symbol [B] go on to alert the rider on the meter panel. In addition, the condition of the problem is stored in the memory of the ECU (electronic control unit).

With the engine stopped and turned in the self-diagnosis mode, the service code [A] is indicated by the number of times the FI indicator LED light blinks. When due to a malfunction, the FI indicator LED light and FI symbol remains lit, ask the rider about the conditions [B] under which the problem occurred and try to determine the cause. Don’t rely solely on the DFI self-diagnosis function, use common sense. First conduct a self-diagnosis inspection, and then a non -self-diagnosis. The non-self-diagnosis items are not indicated by the FI indicator LED light. Even when the DFI system is operating normally, the FI indicator LED light and FI symbol may light up under strong electrical interference. No repair needed. Turn the ignition switch OFF to stop the indicator light and FI symbol. When the FI indicator LED light and FI symbol go on and the motorcycle is brought in for repair, check the service codes. When the repair has been done, the LED light and FI symbol do not go on.

○There are two ways to inspect the DFI system.

One is Voltage Check Method and the other is Resistance Check Method. Voltage Check Method ○This method is conducted by measuring the input voltage [B] to a sensor [A] first, and then the output voltage [C] from the sensor. ○Sometime this method can detect a fault of the ECU. ○Refer to the each Sensor Inspection section for detail in this chapter. Use a fully charged battery, and a digital meter [D] which can be read two decimal places voltage or resistance.

FUEL SYSTEM (DFI) 3-23 Troubleshooting the DFI System

○The DFI part connectors [A] have seals [B], including the

ECU (except for ISC valves). Join the connector [A] and insert the needle adapter (special tool) [C] inside the seal [B] from behind the connector until the adapter reaches the terminal. Special Tool - Needle Adapter Set: 57001-1457

CAUTION Insert the needle adapter straight along the terminal in the connector to prevent short-circuit between terminals. sure that measuring points are correct in the con• Make nector, noting the position of the lock [D] and the lead

color before measurement. Do not reverse connections of the hand tester or a digital meter. Be careful not to short-circuit the leads of the DFI or electrical system parts by contact between adapters. Turn the ignition switch ON and measure the voltage with the connector joined.

CAUTION Incorrect, reverse connection or short circuit by needle adapters could damage the DFI or electrical system parts.

○After measurement, remove the needle adapters and ap-

ply silicone sealant to the seals [A] of the connector [B] for waterproofing. Sealant - Kawasaki Bond (Silicone Sealant): -Seals of Connector

check battery condition before replacing the DFI • Always parts. A fully charged battery is a must for conducting accurate tests of the DFI system.

3-24 FUEL SYSTEM (DFI) Troubleshooting the DFI System Resistance Check Method ○This method is simple. No need for a fully charged battery and the needle adapter. Just do the following especially when a sensor [A] is suspect. Turn the ignition switch OFF and disconnect the connectors. Inspect the sensor resistance, using a digital meter (see each Sensor Inspection in this chapter). Inspect the wiring and connections [B] for continuity, using the hand tester [C] (special tool, analog tester) rather than a digital meter.

• • •

Special Tool - Hand Tester: 57001-1394

If the sensor, the wiring and connections are good, inspect the ECU for its ground and power supply (see ECU Power Supply Inspection in this chapter). If the ground and power supply are good, the ECU is suspect. Replace the ECU.

may involve one or in some cases all items. • Trouble Never replace a defective part without determining what

• •

CAUSED the problem. If the problem was caused by some other item or items, they too must be repaired or replaced, or the new replacement part will soon fail again. Measure coil winding resistance when the DFI part is cold (at room temperature) Make sure all connectors in the circuit are clean and tight, and examine wires for signs of burning, fraying, short, etc. Deteriorated wires and bad connections can cause reappearance of problems and unstable operation of the DFI system.

If any wiring is deteriorated, replace the wiring. Pull each connector [A] apart and inspect it for corrosion, dirt, and damage. If the connector is corroded or dirty, clean it carefully. If it is damaged, replace it. Connect the connectors securely. Check the wiring for continuity. ○Use the wiring diagram to find the ends of the lead which is suspected of being a problem. ○Connect the hand tester between the ends of the leads. ○Set the tester to the × 1 Ω range, and read the tester. If the tester does not read 0 Ω, the lead is defective. Replace the lead.

FUEL SYSTEM (DFI) 3-25 Troubleshooting the DFI System

○If both ends of a harness [A] are far apart, ground [B]

the one end [C], using an auxiliary wire [D] and check the continuity between the end [E] and the ground [F]. This enables to check a long harness for continuity. If the harness is open, repair or replace the harness.

○When checking a harness [A] for short circuit, open one end [B] and check the continuity between the other end [C] and ground [D]. If there is continuity, the harness has a short circuit to ground, and it must be repaired or replaced.

down suspicious locations by repeating the con• Narrow tinuity tests from the ECU connectors. If no abnormality is found in the wiring or connectors, the DFI parts are the next likely suspects. Check the part, starting with input and output voltages. However, there is no way to check the ECU itself. If an abnormality is found, replace the affected DFI part. If no abnormality is found in the wiring, connectors, and DFI parts, replace the ECU. ○The following diagnosis flow chart illustrates the above procedures.

The injector must send signals (output Fuel Injector voltage) 16 or more #1 times continuously to the ECU. The injector must send signals (output Fuel Injector voltage) 16 or more #2 times continuously to the ECU. The pump must send signals (output voltage) Fuel Pump continuously to the ECU.

Backups by ECU If the throttle sensor system fails (the signal is out of the usable range, wiring short or open), the ECU locks ignition timing into the ignition timing at full throttle open position and sets the DFI in the D-J method (1). If the inlet air pressure sensor system fails (the signal Pv is out of the usable range, wiring short or open), the ECU sets the DFI in the α-N method (1). If the inlet air temperature sensor fails (the signal is out of the usable range, wiring short or open), the ECU sets Ta at 45°C. If the water temperature sensor system fails (the signal is out of the usable range, wiring short or open), the ECU sets Tw at 86°C. If the atmospheric pressure sensor system fails (the signal is out of the usable range, wiring short or open), the ECU sets Pa at 760 mmHg (the standard atmospheric pressure). If either crankshaft sensor generates 8 or more signals, the ECU runs the engine by the signal of the good crankshaft sensor, but neither crankshaft sensors generate signals, the engine stops by itself. If the vehicle-down sensor system has failures (the output voltage Vd is out of the usable range, wiring short or open), the ECU shuts off the fuel pump, the fuel injectors and the ignition system. If the injector #1 fails (signals less than 16 times, wiring short or open), the ECU shuts off the signal to the injector. Fuel is not supplied to the cylinder #1, though the engine keeps running. If the injector #2 fails (signals less than 16 times, wiring short or open), the ECU shuts off the signal to the injector. Fuel is not supplied to the cylinder #2, though the engine keeps running. If the fuel pump fails (no signals to ECU, wiring short or open), the ECU shuts off the pump, and then the engine stops because of fuel pressure drop.

If the ignition primary winding #2 has failures (no signal, wiring short or open), the ECU shuts off the injector #2 to stop fuel to the cylinder #2, though the engine keeps running.

Note: (1) When the engine load is light like at idling or low speed, the ECU determines injection quantity by calculating from throttle vacuum (inlet air pressure sensor output voltage) and engine speed (crankshaft sensor output voltage). This method is called D-J method (low-speed mode). As engine speed increases, and the engine load turns middle to heavy, the ECU determines injection quantity by calculating from throttle opening (throttle sensor output voltage) and engine speed. This method is called α-N method (high-speed mode).

1. ECU 2. Atmospheric Pressure Sensor If you need to check the atmospheric pressure sensor for various altitudes other than sea level, check the output voltage as follows: ○Determine the local altitude (elevation). If you know the local atmospheric pressure using a barometer, substitute the atmospheric pressure for Pv (Throttle Vacuum) in the inlet air pressure sensor chart (see Output Voltage Inspection in the Inlet Air Pressure Sensor section). ○Get the usable range of the atmospheric pressure sensor output voltage in the same way as Output Voltage Inspection of the inlet air pressure sensor and check if Va (output voltage) is within the usable range or not. If you know the local altitude, use the following chart. For example: Suppose the local altitude is 1 300 m (4 200 ft) and the sensor output voltage Va is 3.3 V. Plot this H (1 300 m) at a point [1] on the following chart and draw a vertical line through the point. Then, you can get the usable range [2] of the sensor output voltage. Usable Range = 3.2 ∼ 3.64 V Plot Va (3.3 V) on the vertical line → Point [3] Results: In the chart, Va is within the usable range and the sensor is normal.

COOLING SYSTEM 4-7 Coolant Flow Chart Permanent type antifreeze is used as a coolant to protect the cooling system from rust and corrosion. When the engine starts, the water pump turns and the coolant circulates. The thermostat is a wax pellet type which opens or closes as coolant temperature changes. The thermostat continuously changes its valve opening to keep the coolant temperature at the proper level. When coolant temperature is below 58 ∼ 62°C (136 ∼ 144°F), the thermostat closes so that the coolant flow is restricted through the air bleeder hole, causing the engine to warm up more quickly. When coolant temperature is more than 58 ∼ 62°C (136 ∼ 144°F), the thermostat opens and the coolant flows. When the coolant temperature goes up beyond 100 ∼ 110°C (212 ∼ 230°F), the radiator fan switch conducts to operate the radiator fan. The radiator fan draws air through the radiator core when there is not sufficient air flow such as at low speeds. This increases up the cooling action of the radiator. When the temperature is below 97 ∼ 103°C (207 ∼ 217°F), the fan switch opens and the radiator fan stops. In this way, this system controls the engine temperature within narrow limits where the engine operates most efficiently even if the engine load varies. The system is pressurized by the radiator cap to suppress boiling and the resultant air bubbles which can cause engine overheating. As the engine warms up, the coolant in the radiator and the water jacket expands. The excess coolant flows through the radiator cap and hose to the reserve tank to be stored there temporarily. Conversely, as the engine cools down, the coolant in the radiator and the water jacket contracts, and the stored coolant flows back to the radiator from the reserve tank. The radiator cap has two valves. One is a pressure valve which holds the pressure in the system when the engine is running. When the pressure exceeds 93 ∼ 123 kPa (0.95 ∼ 1.25 kgf/cm², 13.5 ∼ 17.8 psi), the pressure valve opens and releases the pressure to the reserve tank. As soon as pressure escapes, the valve closes, and keeps the pressure at 93 ∼ 123 kPa (0.95 ∼ 1.25 kgf/cm², 13.5 ∼ 17.8 psi). When the engine cools down, another small valve (vacuum valve) in the cap opens. As the coolant cools, the coolant contracts to from a vacuum in the system. The vacuum valve opens and allows the coolant from the reserve tank to enter the radiator.

the right side cover (see Right Side Cover Re• Remove moval in the Frame chapter). inspect the coolant [A] in the reservoir tank. • Visually If whitish cotton-like wafts are observed, aluminum parts in the cooling system are corroded. If the coolant is brown, iron or steel parts are rusting. In either case, flash the cooling system. If the coolant gives off an abnormal smell, check for a cooling system leak. It may be caused by exhaust gas leaking into the cooling system.

CAUTION During pressure testing, do not exceed the pressure for which the system is designed. The maximum pressure is 123 kPa (1.25 kgf/cm², 17.8 psi). the gauge for at least 6 seconds. • Watch If the pressure holds 93 kPa (0.95 kgf/cm², 13.5 psi) or

more, the system is all right. If the pressure drops and no external source is found, check for internal leakage. Droplets in the engine oil indicate internal leakage. Check the cylinder head and cylinder gaskets and the water pump. Remove the pressure tester, replenish the coolant, and install the radiator cap.

COOLING SYSTEM 4-9 Coolant Cooling System Flushing Over a period of time, the cooling system accumulates rust, scale, and lime in the water jacket and radiator. When this accumulation is suspected or observed, flush the cooling system. If this accumulation is not removed, it will clog up the water passage and considerably reduce the efficiency of the cooling system. Drain the cooling system (see Coolant Change in the Periodic Maintenance chapter). Fill the cooling system with fresh water mixed with a flushing compound.

5-38 ENGINE TOP END Cylinder Head Seat Cutter Operation Care 1. This valve seat cutter is developed to grind the valve for repair. Therefore the cutter must not be used for other purposes than seat repair. Do not drop or shock the valve seat cutter, or the diamond particles may fall off. Do not fail to apply engine oil to the valve seat cutter before grinding the seat surface. Also wash off ground particles sticking to the cutter with washing oil.

CAUTION Do not use a wire brush to remove the metal particles from the cutter. It will take off the diamond particles. Setting the valve seat cutter holder in position, operate the cutter in one hand. Do not apply too much force to the diamond portion.

NOTE

○Prior to grinding, apply engine oil to the cutter.

During operation, wash off any ground particles sticking to the cutter with washing oil

After use, wash it with washing oil and apply thin layer of engine oil before storing. Operating Procedures Clean the seat area carefully. Coat the seat with machinist’s dye. Fit a 45° cutter [A] into the holder [B] and slide it into the valve guide. Press down lightly on the handle and turn it right or left [C]. Grind the seat surface only until it is smooth.

• • • •

CAUTION Do not grind the seat too much. Overgrinding will reduce valve clearance by sinking the valve into the head. If the valve sinks too far into the head, HLA could not work and the cylinder head must be replaced. the outside diameter [A] of the seat surface (seat • Measure O.D.) with vernier calipers. If the seat O.D. is too small, repeat the 45° grind [B] until the diameter is within the specified range. Ground Voluum [C]

NOTE

○Remove all pittings or flaws from 45° ground surface. ○After grinding with 45° cutter, apply thin coat of machin-

ist’s dye to seat surface. This makes seat surface distinct and 32° and 55° grinding operation easier. ○When the valve guide is replaced, be sure to grind with 45° cutter for centering and good contact. If the seat O.D. is too large, make the 32° grind described below.

ENGINE TOP END 5-39 Cylinder Head

○To make the 32° grind, fit a 32° cutter into the holder, and slide it into the valve guide.

○Turn the holder one turn at a time while pressing down very lightly. Check the seat after each turn.

Oil Level Inspection

the motorcycle so that it is vertical. • Situate Check that engine oil level is between the upper [A] • and lower [B]thelevels in the gauge. Clutch Cover [C]

NOTE

○Situate the motorcycle so that it is perpendicular to the ground.

○If the motorcycle has just been used, wait 2 ∼ 3 minutes for all the oil to drain down. ○If the oil has just been changed, start the engine and run it for several minutes at idle speed. This fills the oil filter with oil. Stop the engine, then wait 2 ∼ 3 minutes until the oil settles.

CAUTION Racing the engine before the oil reaches every part can cause engine seizure. If the engine oil gets extremely low or if the oil pump or oil passages clog up or otherwise do not function properly, the oil pressure warning light will light. If this light stays on when the engine is running above idle speed, stop the engine immediately and find the cause. If the oil level is too high, remove the excess oil, using a syringe or some other suitable device. If the oil level is too low, add the correct amount of oil through the oil filler opening. Use the same type and make of oil that is already in the engine.

NOTE

○If the engine oil type and make are unknown, use any brand of the specified oil to top off the level in preference to running the engine with the oil level low. Then at your earliest convenience, change the oil completely.

• Adjust the wheel balance.

WARNING

Check and balance the wheel when a tire is replaced with a new one. New tires are slippery and may cause loss of control and injury. A break-in period of 160 km (100 mile) is necessary to establish normal tire traction. During break-in, avoid sudden and maximum braking and acceleration, and hard cornering.

Tire Repair Currently two types of repair for tubeless tires have come into wide use. One type is called a temporary (external) repair which can be carried out without removing the tire from the rim, and the other type is called permanent (internal) repair which requires tire removal. It is generally understood that higher running durability is obtained by permanent (internal) repairs than by temporary (external) ones. Also, permanent (internal) repairs have the advantage of permitting a thorough examination for secondary damage not visible from external inspection of the tire. For these reasons, Kawasaki does not recommend temporary (external) repair. Only appropriate permanent (internal) repairs are recommended. Repair methods may vary slightly from make to make. Follow the repair methods indicated by the manufacturer of the repair tools and materials so that safe results can be obtained.

Final Bevel Gear Adjustment

○The backlash and tooth contact pattern of the bevel gears must be correct to prevent the gears from making noise and being damaged. After replacing any of the backlash-related parts, be sure to check and adjust the backlash and tooth contact of the bevel gears. First, adjust backlash, and then tooth contact by replacing shims. ○The amount of backlash is influenced by the ring gear position more than by the pinion gear position. ○Tooth contact locations is influenced by pinion gear position more than by ring gear position.

Front Bevel Gear Adjustment In order to prevent one gear from moving away from the other gear under load, the tapered roller bearings must be properly preloaded. Also the backlash (the distance one gear will move back and forth without moving the other gear) and tooth contact pattern of the bevel gears must be correct to prevent the gears from making noise and being damaged. Above three adjustments are of critical importance and must be carried out in the correct sequence and method. ○Preload adjustment is necessary whenever the driven gear bolt [2] loosened, even if the purpose is not to replace the parts.

Caliper Fluid Seal Damage The fluid seal (piston seal) [A] is placed around the piston to maintain clearance between the pad and the disc. If the seal is in a poor condition, it could lead the pad to wear excessively or the brake to drag, which may cause the temperature of the discs or the brake fluid to increase. Replace the fluid seal if it exhibits any of the conditions listed below. ○Brake fluid leakage around the pad. ○Brakes overheat. ○Considerable difference in inner and outer pad wear. ○Seal and piston are stuck together. If the fluid seal is replaced, replace the dust seal [B] as well. Also, replace all seals every other time the pads are changed. Front Caliper [G] Rear Caliper [H]

Caliper Piston and Cylinder Damage

Caliper Holder Shaft Wear The caliper body must slide smoothly on the caliper holder shafts. If the body does not slide smoothly, one pad will wear more than the other, and constant drag on the disc may cause the temperature of the discs or the brake fluid to increase. Visually inspect that the caliper holder shafts [F] are not badly worn or bent. If the caliper holder shafts are damaged, replace the entire caliper assembly.

Brake Fluid Change

to the Brake Fluid Change in the Periodic Mainte• Refer nance chapter.

Brake Line Bleeding The brake fluid has a very low compression coefficient so that almost all the movement of the brake lever or pedal is transmitted directly to the caliper for braking action. Air, however, is easily compressed. When air enters the brake lines, brake lever or pedal movement will be partially used in compressing the air. This will make the lever or pedal feel spongy, and there will be a loss in braking power.

WARNING Be sure to bleed the air from the brake line whenever brake lever or pedal action feels soft or spongy after the brake fluid is changed, or whenever a brake line fitting has been loosened for any reason.

NOTE

○The procedure to bleed the front brake line is as follows. Bleeding the rear brake line is almost the same as for the front brake.

NOTE

○The fluid level must be checked often during the bleeding operation and replenished with fresh brake fluid as necessary. If the fluid in the reservoir runs completely out any time during bleeding, the bleeding operation must be done over again from the beginning since air will have entered the line. ○Tap the brake hose lightly from the caliper to the reservoir for more complete bleeding. ○Front Brake: Repeat the above steps for the other caliper. the clear plastic hose. • Remove • Tighten:

○First, tighten the rear brake fluid reservoir cap [B] clockwise [C] by hand until the resistance is felt indicating that the cap is seated on the reservoir body, then tighten the cap an additional 1/6 turn [D] while holding the brake fluid reservoir body [A].

BRAKES 12-21 Brake Fluid WARNING When working with the disc brake, observe the precautions listed below. 1. Never reuse old brake fluid. 2. Do not use fluid from a container that has been left unsealed or that has been open for a long time. 3. Do not mix two types and brands of fluid for use in the brake. This lowers the brake fluid boiling point and could cause the brake to be ineffective. It may also cause the rubber brake parts to deteriorate. 4. Don’t leave the reservoir cap off [A] for any length of time to avoid moisture contamination of the fluid. 5. Don’t change the fluid in the rain or when a strong wind is blowing. 6. Except for the disc pads and disc, use only disc brake fluid, isopropyl alcohol, or ethyl alcohol for cleaning brake parts. Do not use any other fluid for cleaning these parts. Gasoline, engine oil, or any other petroleum distillate will cause deterioration of the rubber parts. Oil spilled on any part will be difficult to wash off completely and will eventually deteriorate the rubber used in the disc brake. 7. When handing the disc pads or disc, be careful that no disc brake fluid or any oil gets on them. Clean off any fluid or oil that inadvertently gets on the pads or disc with a high-flash point solvent. Do not use one which will leave an oily residue. Replace the pads with new ones if they cannot be cleaned satisfactorily. 8. Brake fluid quickly ruins painted surfaces; any spilled fluid should be completely washed away immediately. 9. If any of the brake line fittings or the bleed valve is opened at any time, the AIR MUST BE BLED FROM THE BRAKE LINE.

16-24 ELECTRICAL SYSTEM Servicing Precautions There are a number of important precautions that should be followed servicing electrical systems. ○Do not reverse the battery cable connections. This will burn out the diodes on the electrical parts. ○Always check battery condition before condemning other parts of an electrical system. A fully charged battery is a must for conducting accurate electrical system tests. ○The electrical parts should never be struck sharply, as with a hammer, or allowed to fall on a hard surface. Such a shock to the parts can damage them. ○To prevent damage to electrical parts, do not disconnect the battery leads or any other electrical connections when the ignition switch is on, or while the engine is running. ○Because of the large amount of current, never keep the starter button pushed when the starter motor will not turn over, or the current may burn out the starter motor windings. ○Take care not to short the leads that are directly connected to the battery positive (+) terminal to the chassis ground. ○Troubles may involve one or in some cases all items. Never replace a defective part without determining what CAUSED the failure. If the failure was caused by some other item or items, they too must be repaired or replaced, or the new replacement will soon fail again. ○Make sure all connectors in the circuit are clean and tight, and examine wires for signs of burning, fraying, etc. Poor wires and bad connections will affect electrical system operation. ○Measure coil and winding resistance when the part is cold (at room temperature). ○Wire Color Codes: BK: Black BL: Blue BR: Brown CH: Chocolate DG: Dark green

Battery Model Name for VN1600-D1: FTZ16-BS

CAUTION Be sure to use the electrolyte container with the same model name as the battery since the electrolyte volume and specific gravity vary with the battery type. This is to prevent overfilling of the electrolyte, shorting the battery life, and deterioration of the battery performance.

CAUTION Do not remove the aluminum sealing sheet [A] from the filler ports [B] until just prior to use. Be sure to use the dedicated electrolyte container for correct electrolyte volume. the battery on a level surface. • Place Check • or holestoinseeit. that the sealing sheet has no peeling, tears, • Remove the sealing sheet.

○Do not tilt the electrolyte container the electrolyte flow. • Check If no air bubbles [A] are coming up from the filler ports, or

if the container cells have not emptied completely, tap the container [B] a few times. Keep the container in place for 20 minutes or more. Don’t remove the container from the battery until it’s empty, the battery requires all the electrolyte from the container for proper operation.

CAUTION Removal of the container before it is completely empty can shorten the service life of the battery. Do not remove the electrolyte container until it is completely empty and 20 minutes have elapsed. remove the container from the battery. • Gently Let the battery sit for 60 minutes prior to charging to allow • the electrolyte to permeate into the plates for optimum performance.

○Charging

CAUTION Once the strip of the caps [A] is installed onto the battery, never remove the caps, nor add water or electrolyte to the battery.

NOTE

○To ensure maximum battery life and customer satisfac-

tion, it is recommended the battery be load tested at three times its amp-hour rating for 15 seconds. Re-check voltage and if less than 12.6 volts repeat the charging cycle and load test. If still below 12.6 volts the battery is defective.

Precautions 1) No need of topping-up No topping-up is necessary in this battery until it ends its life under normal use. Forcibly prying off the seal cap to add water is very dangerous. Never do that. 2) Refreshing charge If an engine will not start, a horn sounds weak, or lamps are dim, it indicates the battery has been discharged. Give refresh charge for 5 to 10 hours with charge current shown in the specification (see this chapter). When a fast charge is inevitably required, do it following precisely the maximum charge current and time conditions indicated on the battery.

CAUTION This battery is designed to sustain no unusual deterioration if refresh-charged according to the method specified above. However, the battery’s performance may be reduced noticeably if charged under conditions other than given above. Never remove the seal cap during refresh charge. If by chance an excessive amount of gas is generated due to overcharging, the relief valve releases the gas to keep the battery normal. 3) When you do not use the motorcycle for months: Give a refresh charge before you store the motorcycle and store it with the negative cable removed. Give a refresh charge once a month during storage. 4) Battery life: If the battery will not start the engine even after several refresh charges, the battery has exceeded its useful life. Replace it (Provided, however, the vehicle’s starting system has no problem).

WARNING Keep the battery away from sparks and open flames during charging, since the battery gives off an explosive gas mixture of hydrogen and oxygen. When using a battery charger, connect the battery to the charger before turning on the charger. This procedure prevents sparks at the battery terminals which could ignite any battery gases. No fire should be drawn near the battery, or no terminals should have the tightening loosened. The electrolyte contains sulfuric acid. Be careful not to have it touch your skin or eyes. If touched, wash it off with liberal amount of water. Get medial attention if severe.

ELECTRICAL SYSTEM 16-31 Battery Interchange The sealed battery can fully display its performance only when combined with a proper vehicle electric system. Therefore, replace the sealed battery only on a motorcycle which was originally equipped with the sealed battery. Be careful, if the sealed battery is installed on a motorcycle which had an ordinary battery as original equipment, the sealed battery’s life will be shortened.

CAUTION Be sure to disconnect the negative (–) cable first.

• Measure the battery terminal voltage. NOTE

○Measure with a digital voltmeter which can be read one decimal place voltage.

headlight turned on and then turned off (To turn off the headlight, disconnect the headlight connector in the headlight unit). The readings should show nearly battery voltage when the engine speed is low, and as the engine speed rises, the readings should also rise. But they must be kept under the specified voltage. Turn off the ignition switch to stop the engine, and disconnect the hand tester. If the charging voltage is kept between the values given in the table, the charging system is considered to be working normally. If the output voltage is much higher than the values specified in the table, the regulator/rectifier is defective or the regulator/rectifier leads are loose or open. If the battery voltage does not rise as the engine speed increases, then the regulator/rectifier is defective or the alternator output is insufficient for the loads. Check the alternator and regulator/rectifier to determine which part is defective.

ELECTRICAL SYSTEM 16-39 Charging System Alternator Inspection There are three types of alternator failures: short, open (lead burned out), or loss in rotor magnetism. A short or open in one of the stator coil lead will result in either a low output, or no output at all. A loss in rotor magnetism, which may be caused by dropping or hitting the alternator, by leaving it near an electromagnetic field, or just by aging, will result in low output. check the alternator output voltage, do the following • To procedures.

If there is more resistance than shown in the table, or no hand tester reading (infinity), the stator has an open wire and must be replaced. Much less than this resistance means the stator is shorted, and must be replaced. Using the highest resistance range of the hand tester, measure the resistance between each of the black leads and chassis ground. Any hand tester reading less than infinity (∞) indicates a short, necessitating stator replacement. If the stator coil has normal resistance, but the voltage check showed the alternator to be defective, then the rotor magnets have probably weakened, and the rotor must be replaced. ○Repeat the test for the other black leads. ○Repeat the test for the inside alternator connector.

ELECTRICAL SYSTEM 16-67 Automatic Turn Signal Canceling System Automobiles use a turn signal canceling system actuated by steering wheel turn. But, motorcycles turn with a bank additionally, and so have a smaller steer angle. This makes difficult to adopt an automobile type turn signal canceling system because of inaccurate operation in motorcycles. So, motorcycles adopt time & distance counting system. The canceling system consists of a battery, turn signal control relay, distance sensor, and turn signal switch. When the turn signal switch is pushed onto the right or left, the turn signals start flashing and the control relay starts counting off 8 seconds. At the end of this time, the control relay starts calculating distance traveled using pulses from the distance sensor in the speedometer. The control relay keeps working even after the tern signal switch was released and returned to the neutral position by spring force. When the motorcycle has traveled an additional 65 meters (213 foots), the control relay shuts off the current, turns off the turn signal lights, and resets itself. If the turn signal canceling system does not function properly, first check all the wiring connections carefully. Secondly, inspect the distance sensor. Thirdly, inspect the turn signal switch in the left handlebar switch. Lastly, check the turn signal control relay.

17-28 APPENDIX Troubleshooting Guide NOTE

○Refer to Fuel System chapter for most of

DFI troubleshooting guide. ○This is not an exhaustive list, giving every possible cause for each problem listed. It is meant simply as a rough guide to assist the troubleshooting for some of the more common difficulties.

Engine Doesn’t Start, Starting Difficulty Starter motor not rotating Starter lockout switch or neutral switch trouble Starter motor trouble Battery voltage low Starter relays not contacting or operating Starter button not contacting Wiring open or shorted Ignition switch trouble Engine stop switch trouble Fuse blown Starter motor rotating but engine doesn’t turn over Starter clutch trouble Vehicle-down sensor coming off Engine won’t turn over Valve seizure Rocker arm seizure Cylinder, piston seizure Crankshaft seizure Connecting rod small end seizure Connecting rod big end seizure Transmission gear or bearing seizure Camshaft seizure Balancer bearing seizure No fuel flow No fuel in tank Fuel pump trouble Fuel tank air vent obstructed Fuel filter clogged Fuel line clogged Engine flooded Clean spark plugs and adjust plug gaps Starting technique faulty (When flooded, do not crank the engine with the throttle fully opened. This promotes engine flood because more fuel is supplied automatically by DFI.) No spark; spark weak Vehicle-down sensor coming off Ignition switch not ON Engine stop switch turned off Clutch lever not pulled in and gear not in neutral whether side stand up or down Though clutch lever pulled in, side stand up and gear not in neutral

Battery voltage low Spark plug dirty, broken, or gap maladjusted Spark plug cap or high tension wiring trouble Spark plug cap shorted or not in good contact Spark plug incorrect IC igniter in ECU trouble Neutral, starter lockout, or side stand switch trouble Crankshaft position sensor trouble Ignition coil trouble Ignition switch or engine stop switch shorted Wiring shorted or open Fuse blown Fuel/air mixture incorrect Air cleaner clogged, poorly sealed, or missing Compression Low Spark plug loose Cylinder head not sufficiently tightened down Cylinder, piston worn Piston ring bad (worn, weak, broken, or sticking) Piston ring/groove clearance excessive Cylinder head gasket damaged Cylinder head warped Valve spring broken or weak Valve not seating properly (valve bent, worn, or carbon accumulation on the seating surface) KACR (compression release cam) sticks open (engine stalls when moving off) HLA (hydraulic lash adjuster) damaged (worn, seizure, or spring broken) HLA oil passage clogged
