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 in-
cludes a catalytic converter system.
3. Evaporative Emission Control System Vapors caused by fuel evaporation in the fuel system are not vented into the atmosphere. In-
stead, 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 f leet of m otor 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 a s follows :
1. Tampering does not include the temporary removal or rendering inoperative of de­vices or elements of design in o rder to perform maintenance.
2. Tampering could include:
a.Maladjustment of vehicle components such that the emission standards are ex-
ceeded.
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 stan-
dards.
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,
THEVIOLATIONOFWHICHISPUNISHABLEBYCIVILPENALTIESNOTEXCEEDING $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.

Foreword

This manual is designed primarily for use by trained mechanics in a properly equipped shop. However, it contains enough detail and basic in­formation to make it useful to the owner who de­sires to perform his own basic maintenance and repair work. A basic knowledge of mechanics, the proper use of tools, and workshop proce­dures must be understood in order to carry out maintenance and repair satisfactorily. When­ever the owner has insufficient experience or doubts his ability to do the work, all adjust­ments, maintenance, and repair should be car­ried out only by qualified mechanics.

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 w hen 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.
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.
GENERAL INFORMATION 1-3
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 K AWASAKI. 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
Bolts, nuts, or screws must be tightened according to the specified sequence to prevent case warpage or deformation which can lead to malfunction. 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. Often, the tightening sequence is followed twice-initial tightening and final tightening with 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, Or ing
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, Locking Agent
For applications that require Liquid Gasket or a Locking agent, clean the surfaces so that no oil residue remains be­fore applying liquid gasket or locking agent. Do not apply them excessively. Excessive application can clog oil pas­sages and cause serious damage.
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.
GENERAL INFORMATION 1-5
Oil Seal, Grease Seal
Do not remove pressed oil or grease seals unless r emoval 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.
Circlips, Cotter Pins
Replace circlips or cotter pins that were removed with new ones. Install the circlip with its sharp edge facing outward and its chamfered side facing inward to prevent the clip from being pushed out of its groove when loaded. Take care not to open the clip excessively when installing to prevent deformation.
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.
1-6 GENERAL INFORMATION
Before Servicing
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 right 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.

Technical Information – Oxygen Sensor

Overview

Kawasaki has adopted an oxygen sensor [A] for the Euro­pean and California models in addition to the secondary air injection system and honeycomb catalyst. This helps Ka­sawaki keep the motorcycle with cleaner exhaust gas and cope with the emission regulations.
The oxygen sensor [A] is mounted above the exhaust manifold [B], w hereas the honeycomb catalyst is located inside the silencer in the downstream of the exhaust gas.
GENERAL INFORMATION 1-11
The oxygen sensor uses the substance called zirconia (ZrO
2). The electromotive force varies depending on the
density of the oxygen. The sensor measures the oxygen density of the exhaust gas to detect whether the air/fuel mixture is lean or rich in relation to the optimum air/fuel mixture.
When the ECU is in the oxygen sensor feedback mode, it controls combustion by making the fuel injection amount of the injector rich or lean through the signal from the sensor.
1-12 GENERAL INFORMATION
Technical Information – Oxygen Sensor
Construction and Operation
The oxygen sensor uses, a solid electrolyte called zirco-
nia.
An electrolyte is a substance that has positive (+) and
negative () ions and can move freely i n a liquid.
For explanation purposes, picture a solid electrolyte plate as a wall and chambers A and B are divided by this wall. If both sides of the wall have platinum electrodes with holes, the difference in oxygen density (weight) between cham­bers A and B will move the oxygen from the chamber of higher oxygen density to the chamber of lower oxygen den­sity until the two chambers are about equal in density. What actually moves are the oxygen ions () through the wall of the solid electrolyte.
The higher-density-side chamber will receive the “Pt” electrode surface with holes on the solid electrolyte wall and will become minus the oxygen ions (O the O
2ions reach the “Pt” electrode of the opposite side.
Since the result of this O “e
” (just like “cells” w ork in a battery), voltage will be built
2move also brings movement of
within the sensor.
2). At this point,
The (conceptual) sectional view of the actual element in the oxygen sensor is shown. The sensor is exposed to ex­haust gas. The shape of the sensor is tubular since the at­mospheric side and exhaust gas side are parted by the wall. That means that the inside of this tubular solid electrolyte is the atmosphere side (higher oxygen density), and the out­side of the tube faces the exhaust gas. The outside surface, which is in the stream of exhaust gases, has a coated layer of porous ceramic. Voltage is generated and can be mea­sured because of the difference in oxygen density (positive and negative ions).
Technical Information – Oxygen Sensor
The sensor, uses the fresh air as the oxygen reference, and consists of a passageway to lead the fresh air inside the tubular element. Installed in this passageway is, a air permeable filter that allows the fresh air to pass through, but won’t allow moisture through. This keeps the sensor in touch with the atmosphere.
At a normal temperature, Zirconia (solid electrolyte) is an insulator and not able to sense the gases. Since the exhaust gas temperature does not become hot instantly, it takes sometime before the sensor starts to work. To solve the problem of the slow temperature increase of ex­haust gases (which warms the electrolyte element), a built
-in heater located i nside the tubular element increases the temperature of the sensor so it can operate at a low ex­haust gas temperature. Furthermore this built-in heater helps keep the sensor at a constant temperature.
GENERAL INFORMATION 1-13
Air/Fuel Ratio Control By Oxygen Sensor
λ=1” indicates the optimum air/fuel ratio point, meaning the air/fuel ratio at which optimum (complete) combustion can be obtained. In the proximity of this mixture, the purifi­cation efficiency of the catalyst will be maximized.
The purification ratio of the three kinds of gas, HC (hy­drocarbons), CO (carbon monoxide), Nox (nitrogen oxides) using the ternary (three) catalyst is shown in Fig. 4.
The best purification rate is at the zone where the oxy­gen sensor ’s signal shows the sharp changes. This zone is called the “window” and if the oxygen sensor signal moves back and forth between the rich side (fuel rich) and lean side (fuel lean) from the oprimum mix ratio (but still within the width of the window), it indicates that the exhaust gas is in a good purification rate zone.
1-14 GENERAL INFORMATION
Technical Information – Oxygen Sensor
Figure 5 shows how the sensor operates the controlling
factors.
There is a sharp voltage drop of about 1V (in reality, about
0.9 V) the sensor uses for control (a standard reference). By utilizing this voltage and using 0.45 V as the reference line, an output larger than the line indicates that exhaust gas is in the lean zone. So, when the system senses a “rich” condition through the sensor’s output voltage, it controls the fuel injection amount to make the fuel gradually leaner. When it reaches a leaner point, the sensor voltage signal drops sharply at the proximity λ=1 and goes below 0.45V. The system, at this level, senses that it has changed to “lean” and reverse the voltage signal to make the fuel richer. It then controls the fuel injection amount to make the fuel gradually richer. When it drops to a richer point, the signal drops sharply at the proximity λ=1 and goes over 0.45V. The system, at this level, senses that it has changed to “rich” and reverse the signal to make the fuel leaner. By having the signal repeat back and forth between the rich and lean sides, it can constantly stay within the window of the good purification rates. Thereby the oxygen sensor, works as a combustion control sensor for the optimum air/fuel ratio.
Technical Information – Oxygen Sensor
Maintenance
1) Periodic Inspections
Periodic inspections or special maintenance is not re­quired for the sensor.
2) Oxygen Sensor Removal and Installation
Handle the oxygen sensor with care. Be careful not to damage sensor wires. Do not service the oxygen sensor while it is hot and not use an inpact wrench while removing or installing the oxygen sensor. Avoid the fouling (damaging) of the sensing part of the sensor with foreign substances such as coolant, battery fluid, anti-corrosion fluid, and brake fluid. Stop using the sensor if it is fouled with these sub­stances. Also stop using the sensor if the head part of the sensor (exposed to the atmosphere) is fouled. Since the sen­sor has a filter that allows air to escape but stop water, fouling of the sensor head may clog this filter. Being subjected to a flame is also unacceptable for the sensor with the same reason as above.
3) Condition of the Sensor
Perform resistance measurements and visually check for scars, bends, and clogging of the sensor filter.
4) If trouble with the sensor occurs, one of the following
service codes will be displayed. Accordingly, follow the related procedures in the Service Manual for necessary maintenance.

1-16 GENERAL INFORMATION
Technical Information – Electric Solenoid Operated Decompressor
An automatic decompressor (Automatic Compression Reliese) system is installed to the right side of the engine. This decompressor is activated by an electric solenoid to make starting engine easy. When the ignition is switched on and the starter button depressed, the solenoid pulls a fulcrum-mounted link that depresses push rods in each camshaft.
The push rods activate the decompression mechanism to partially open the exhaust valves as the piston nears top dead center, releasing some of compression that can cause resistance during starting.
Releasing the starter button de-activates the solenoid and a spring returns the push rods to their normal operating po­sition.

Torque and Locking Agent
PERIODIC MAINTENANCE 2-5
The following tables list the tightening torque
for the m ajor fasteners requiring use of a non
-permanent locking agent or liquid gasket.
Letters used in the “Remarks” column mean:
L: Apply a non-permanent locking agent to
the threads.
G: Apply grease to the threads.
MO: Apply molybdenum disulfide grease oil
solution.
O: Apply oil to the threads and seating sur-
face.
S: Tighten the fasteners following the speci-
fied sequence.
SS: Apply silicone sealant.
Si: Apply silicone grease (ex. PBC grease).
R: Replacement parts
Lh: Left-hand-threads
St: Stake the fasteners to prevent loosening.
AL: Tighten the two clamp bolts alternately
two times to ensure even tightening torque.
The table below, relating tightening torque to thread diameter, lists the basic torque for the bolts and nuts. Use this table for only the bolts and nuts which do not require a specific torque value. All of the values are for use with dry solvent-cleaned threads.

Steering Play Inspection
Check steering as follows.
Use the jack [A] and jack attachment [B] under the frame
pipe, and a commercially available jack [C] under the en­gine to lift the front wheel off the ground.
Special Tools - Jack: 57001-1238
Jack Attachment: 57001-1571
With the front wheel pointing straight ahead, alternately
tap each end of the handlebar. The front wheel should swing fully right and left from the force of gravity until the fork hits the stop. If the wheel binds or catches before the stop, the steering is too tight.
Feel for steering looseness by pushing and pulling [A] the
fork. If you feel looseness, the steering is too loose.
NOTE
The cables and wiring will have some effect on the mo-
tion of the fork which must be taken into account. Be sure the wires and cables are properly routed. The bearings must be in good condition and properly
lubricated in order for any test to be valid.
Steering Play Adjustment
Adjust the steering, if necessary. Remove:
Nacelle (see Frame chapter) Handlebar (see Steering chapter) Stem Head Nut [A] Washer
Loosen the upper fork clamp bolts on both sides.
Remove:
O-ring [A] Steering Stem Head [B]
Periodic Maintenance Procedures

Run the throttle cables, brake hose, and clutch cable in
accordance with the Cable, Wire, and Hose Routing sec­tion in the Appendix chapter. Check and adjust the steering and throttle cables after
installation.
WARNING
Do not attempt to ride the m otorcycle until a full brake lever is obtained by pumping the brake lever until the pads are against the disc. The brakes will not function on the first application of the lever if this is not done.
PERIODIC MAINTENANCE 2-15
Steering Stem Bearing Lubrication
Remove the steering stem. (see Steering chapter).
Using a high-flash point solvent, wash the upper and
lower tapered roller bearings [A] in the cages, and wipe the upper and lower outer races, which are press-fitted into the frame head pipe, clean of grease and dirt. Visually check the outer races and the rollers.
If the rollers or races are worn, or if either race is dented, replace both races and all the roller bearings as a set (see Steering chapter). Pack the upper and lower tapered roller in the cages with
grease, and apply a light coat of grease to the upper and lower outer races. Install the steering stem, and adjust the steering (see
Steering chapter).
Brake System:

Inspect the brake hose routing.
If any brake hose routing is incorrect, route the brake hose according to Cable, Wire and Hose Routing section in the Appendix chapter.
Brake Operation Inspection
Inspect the operation of the front and rear brake by run-
ning the vehicle on the dry road. If the brake operation is insufficiency, inspect the brake system.
WARNING
When inspecting by running the vehicle, note a surrounding traffic situation enough in the place of safety.
Brake F luid Level Inspection
Check that the brake fluid level in the front brake reservoir
[A] is above the lower level line [B].
NOTE
Hold the reservoir horizontal by turning the handlebar
when checking brake fluid level.
If the fluid level is lower than the lower level line, fill the reservoir to the upper level line [A] in the reservoir [B].
Periodic Maintenance Procedures
Check that the brake fluid level in the rear brake reservoir
[A] is between the upper [B] and the lower [C] level lines. If the fluid level is lower than the lower level line, fill the reservoir to the upper level line. Use extra heavy-duty brake fluid only from a container
marked DOT4. Brake fluid of DOT4 is installed in the brake system when
shipped.
T orque - Front Brake Reservoir Cap Screws: 1.5 N·m (0.15
kgf·m, 13 in·lb)
WARNING
Do not mix two brands of fluid. Change the brake fluid in the brake line completely if the brake fluid must be refilled but the type and brand of the brake fluid that is already in the reservoir are unidentified. After changing the fluid, use only the same type and brand of fluid thereafter.
PERIODIC MAINTENANCE 2-17
Brake Pad Wear Inspection
Check the lining thickness [A] of the pads in each caliper.
If the lining thickness of either pad is less than the service limit [B], replace both pads in the caliper as a set (see Brakes chapter).

Pad Lining Thickness

Standard:
Front: Rear:
Service Limit: 1 mm (0.04 in.)
Brake Light Switch Operation

2-18 PERIODIC MAINTENANCE
Periodic Maintenance Procedures
If it does not go on, inspect or replace the following item.
Battery (see Electrical System chapter) Brake Light Bulb (see Electrical System chapter) Main Fuse 30 A and Taillight Fuse 10 A (see Electrical System chapter) Front Brake Light Switch [A] ( see Electrical System chapter) Rear Brake Light Switch (see Electrical System chapter) Harness (see Wiring Inspection in Electrical System chapter)
Wheel and Tires:
Tire Air Pressure Inspection
Measure the tire air pressure with an air pressure gauge
[A] when the tires are cold (that is, when the motorcycle has not been ridden more than a mile during the past 3 hours.) Adjust the tire air pressure according to the specifications if necessary.

Air Pressure (when cold)

Front Upto186kg(410lb) 250 kPa (2.5 kgf/cm², 36 psi)
Rear
Upto186kg(410lb) 290 kPa (3.0 kgf/cm², 42 psi)
WARNING
To ensure safe handling and stability, use only the recommended standard tires for replacement, in­flated to the standard pressure. Use the same man­ufacture’s tires on both front and rear wheels.
NOTE
Most countries may have their own regulations requiring
a minimum tire tread depth; be sure to follow them. Check and balance the wheel when a tire is replaced
with a new one (see Wheels/Tires chapter).
Wheel/Tire Damage Inspection
Remove any imbedded stones [A] or other foreign parti-
cles [B] from tread. Visually inspect the tire for cracks and cuts replacing the
tire in case of damage. Swelling or high spots indicate internal damage, requiring tire replacement. Visually inspect the wheel for cracks, cuts and dents dam-
age. If any damage is found, replace the wheel if necessary.
Tire Tread Wear Inspection
As the tire tread wears down, the tire becomes more sus­ceptible to puncture and failure. An accepted estimate is that 90% of all tire failures occur during the last 10% of tread life (90% worn). So it is false economy and unsafe to use the tires until they are bald.
Periodic Maintenance Procedures
Measure the tread depth at the center of the tread with a
depth gauge [A]. Since the tire may wear unevenly, take measurement at several places. If any measurement is less than the service limit, replace the tire (see Wheels/Tires chapter).

Tread Depth

Front:
Standard: 4.3 mm (0.17 in.) Service Limit: 1 mm (0.04 in.)
(DE, AT, CH) 1.6 mm (0.063 in.)
Rear:
Standard: 7.0 mm (0.28 in.) Service Limit: 2 mm (0.08 in.):
Up to 130 km/h (80 mph)
3mm(0.1in.):
Over to 130 km/h (80 mph)
Wheel Bearing Damage Inspection
Using a jack and attachment, raise the front wheel off the
ground (see Wheels/Tires chapter). Turn the handlebar all the way to the right or left.
Inspect the roughness of the front wheel bearing by push-
ing and pulling [A] the wheel. Spin [B] the front wheel lightly, and check for smoothly
turn, roughness, binding or noise. If roughness, binding or noise is found, remove the front wheel and inspect the wheel bearing (see Wheels/Tires chapter).
PERIODIC MAINTENANCE 2-19
Using a jack and attachment, raise the rear wheel off the
ground (see Wheels/Tires chapter). Inspect the roughness of the rear wheel bearing by push-
ing and pulling [A] the wheel. Spin [B] the rear wheel lightly, and check for smoothly
turn, roughness, binding or noise. If roughness, binding or noise is found, remove the rear wheel and inspect the wheel bearing (see Wheels/Tires chapter) and coupling (see Final Drive chapter).
Suspensions
Front Forks/Rear Shock Absorber Operation Inspection
Pump the forks down and up [A] 4 or 5 times, and inspect
the smooth stroke. If the forks do not smoothly or noise is found, inspect the fork oil level or fork clamps (see Suspension chapter).
2-20 PERIODIC MAINTENANCE
Periodic Maintenance Procedures
Pump the seat down and up [A] 4 or 5 times, and inspect
the smooth stroke.
If the shock absorber does not smoothly or noise is found,
inspect the oil leak (see Rear Shock Absorber Oil Leak
Inspection) or shock absorber clamps (see Suspension
chapter).
Front Fork Oil Leak Inspection
Visually inspect the front forks [A] for oil leakage.
Replace or repair any defective parts, if necessary.
Rear Shock Absorber Oil Leak Inspection
Remove:
Seats (see Frame chapter) Battery Cover
Visually inspect the shock absorber [A] for oil leakage.

seals.
Install the swingarm (see Suspension chapter).
Periodic Maintenance Procedures
Clutch and Drive Train:
Clutch Operation
Pull the clutch lever just enough to take up the free play
[A]. Measure the gap between the lever and the lever holder.
If the gap is too wide, the clutch may not release fully. If the gap is too narrow, the clutch may not engage fully. In either case, adjust it.

Clutch Lever Free Play

Standard: 2 3mm(0.080.12 in.)
WARNING
To avoid a serious burn, never touch the or exhaust pipe during clutch adjustment.
Loosen the locknut [A] at the clutch lever.
Turn the adjuster [B] until the proper amount of clutch
lever free play is obtained. Tighten the l ocknut securely.
If it cannot be done, use the adjuster at the middle of the cable.
PERIODIC MAINTENANCE 2-21
Loosen the locknut [A] at the middle of the clutch cable.
Turn the adjusting nut [B] until the proper amount of clutch
lever free play is obtained. Tighten the l ocknut securely.
WARNING
Be sure that the outer cable end at the clutch lever is fully seated in the adjuster at the clutch lever, or it could slip into place later, creating enough cable play to prevent clutch disengagement.
After the adjustment, start the engine and check that the
clutch does not slip and that it releases properly.
Belt Deflection Inspection
NOTE
Belt deflection must be checked and adjusted when the
belt is cold (at room temperature). Belt deflection also should be checked at first 1000 km
ride after belt replacement.
Check to see if wheel alignment is properly adjusted.
The left and right notches on the belt adjuster should point
to the same marks or positions on the swingarm. If they do not, adjust wheel alignment (see Wheel Align­ment Inspection/Adjustment).
2-22 PERIODIC MAINTENANCE
Periodic Maintenance Procedures
Using the jack and jack attachment under the frame pipe
ribs, lift the rear wheel off the ground (see Rear Wheel
Removal in the Wheels/Tires chapter).
Visually inspect the belt for damage (see Belt Wear and

If the belt is damaged, replace it with a new one.
Mark the initial belt position [C] on the belt cover window.
Using the tension gauge [A], push up 45 N (4.5 kgf, 10
lb) of force from under and on the center of the belt at the
gauge of the lower belt cover [B].
Measure the deflection (length between mark [D] and [C])
of the belt.
NOTE
Push the belt by the gauge until the top surface [A] of
the stopper comes to the 45 N l oaded scale [B], marked “45N”. Push up on the center of the belt. An inaccurate reading
will occur if the edge of the belt is pushed up. Look parallel to the belt during inspection. An inaccu-
rate reading will occur if looking from any other angle.
Inspect the belt deflection at two positions by rotating the
rear wheel.
Special Tools - Drive Belt Tension Gauge: 57001-1585

Throttle Control System Inspection
Check the throttle grip free play [A].
If the free play is incorrect, adjust the throttle cable (see below).

Throttle Grip Free Play

Standard: 2 ~ 3 mm (0.08 ~ 0.12 in.)
Check that the throttle grip moves smoothly from close to
full open, and the throttle closes quickly and completely in all steering positions by the return spring. If the throttle grip doesn’t return properly, check the throt­tle cable routing, grip free play, and cable damage. Then lubricate the throttle cable. Run the engine at the idle speed, and turn the handlebar
all the way to the right and left to ensure t hat the idle speed doesn’t change. If the idle speed increases, check the throttle grip free play and the cable routing.
If necessary, adjust the throttle cable as follows:
Loosen the locknuts [A] and screw the adjusters [B] all the
way in so as to give the throttle grip plenty of play (rear view). Turn out the adjuster of the decelerator cable [D] until
thereisnoplay. Tighten the locknut against the adjuster.
Turn the adjuster of the accelerator cable [C] until the
proper amount of throttle grip free play is obtained and tighten the locknut against the adjuster.
Periodic Maintenance Procedures
Idle Speed Inspection
Start the engine and warm it up thoroughly.
At first the engine will run fast to decrease warm up time
(fast idle). Gradually the fast idle will lower to a certain RPM auto-
matically. This is the idle speed. Check the idle speed.

Idle Speed

Standard: 900 ± 50 r/min (rpm)
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.
PERIODIC MAINTENANCE 2-33
If the idle speed is out of the specified range, adjust it. Start the engine and warm it up thoroughly.
Wait until fast idle speed lowers to a certain value.
Turn the adjusting screw [A] until the idle speed is correct.
Open and close the throttle a few times to make sure that
the idle speed is within the specified range. Readjust if necessary.
Front [B]
Fuel Hose and Connection Inspection
The fuel hose [ A] is 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 or the hose to burst. Remove the fuel tank (see 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 hose joints are securely connected.
When installing the fuel hoses, avoid sharp bending, kink-
ing, flattening or twisting. Replace the hose if it has been sharply bent or kinked flattening or twisting.
2-34 PERIODIC MAINTENANCE
Periodic Maintenance Procedures
Cooling System
Coolant Level Inspection
NOTE
Check the level when the engine is cold (room or ambi-
ent temperature).
Check the coolant level in the reserve tank with the motor-
cycle held upright. The coolant level should be between the “F” (full) level and the “L” (low) level (In the photo, the mufflers have been removed for clarity).
Front [A]
Reserve Tank [B]
Coolant Level Hose [C]
“F” Level [D]
“L” Level [E] If the coolant level is lower than the “L” level, remove the reserve tank cap, then add coolant to the“F” level.
CAUTION
For refilling, add t he 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 and Connection Inspection
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 i t 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.
