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 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 “remo ve 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 ex-

ceeded.

b.Use of replacement p arts 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,

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.

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.

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.

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 cables from the battery to prevent the en­gine from accidentally turning over. Disconnect the ground
cable (–) first and then the positive (+). When completed
with the service, first connect the positive (+) cable to the
positive (+) terminal of the battery then the negative (–) ca­ble 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.

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 Remov ed 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 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 the old gaskets and clean the sealing surfaces
thoroughly so that no gasket material or other material re­mains. Install the new gaskets and replace the 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.

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 i nner 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 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 the 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.

Instrument

Use a meter that has enough accuracy for an accurate
measurement. Read the manufacture’s instructions thor­oughly before using the meter. Incorrect values may lead
to improper adjustments.

Torque and Locking Agent

Use a torque wrench to tighten bolts and nuts to their specified torque values. If too little torque is
applied, the bolts and nuts could loosen and fall out. If too much torque is applied, the threads could
be sheared off.

To tighten a bolt or a nut, or to check their torque, loosen the bolt or nut one-half turn before tight­ening it to the specified torque.

Letters used in the “Remarks” column mean:

EO: Apply engine oil.

G: Apply grease.

L: Apply a non-permanent locking agent to the threads.

M: Apply molybdenum disulfide grease.

MO: Apply molybdenum disulfide oil solution.

R: Replacement Parts

S: Tighten the fasteners following the specified sequence.

Si: Apply silicone grease.

SS: Apply silicone sealant.
