Read OWNER'S MANUAL before operating

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 mechan-
ics, 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 adjust-
ments, 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, thor-
oughly 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 your warranty period,
especially, we recommend that all repairs and
scheduled maintenance be performed in accord-
ance 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 vehicle
parts. Special tools, gauges, and testers
that are necessary when servicing Kawasaki
vehicles are introduced by the Special Tool
Manual. Genuine parts provided as spare parts
are listed in t he Parts Catalog.
-Follow the procedures in this manual carefully.
Don't take shortcuts.
_ Remember to keep complete records of main-
tenance and repair with dates and any new
parts installed.
How to Use this Manual
In preparing this manual, we divided the
product into its major systems. These systems
became the manual's chapters. All information
for a particular system from adjustment
through disassembly and inspection is located in
a single chapter.
The Quick Reference Guide shows you all of
the product's systems and assists in locating
their chapters. Each chapter in turn has its own
comprehensive Table of Contents.
The Periodic Maintenance Chart is located in
the General Information chapter. The chart
gives a time schedule for required maintenance
operations.
If you want spark plug information, for
example, go to the Periodic Maintenance Chart
first. The chart tells you how frequently to
clean and gap the plug. Next, use the Quick
Reference Guide to locate the Electrical System
chapter. Then, use the Table of Contents on the
first page of the chapter to find the Spark Plug
section.
Whenever you see these WARNING and
CAUTION symbols, heed their instructions!
Always follow safe operating and maintenance
practices.
I WARNING.
oThis warning symbol identifies special instruc-
tions or procedures which, if not correctly
followed, could result in personal injury, or
loss of life.
oThis caution symbol identifies special instruc-
tions or procedures which, if not strictly
observed, could result in damage to or destruc-
tion of equipment.
This manual contains five more symbols (in
addition to WARNING and CAUTION) which
will help you distinguish different types of
information.
NOTE
o This note symbol indicates points of particular
interest for more efficient and convenient
operation.

elndicates a procedural step or work to be done.
o lndicates a procedural sub-step or how to do
the work of the procedural step it follows.
It also precedes the text of a WARNING,
CAUTION, or NOTE.
*Indicates a conditional step or what action to
take based on the results of the test or inspec-
tion in the procedural step or sub-step it
follows.
<r Indicates a conditional sub-step or what action
to take based upon the results of the condi-
tional step it follows.
In most chapters an exploded view illustration
of the system components follows the Table of
Contents. In these illustrations you will find
the instructions indicating which parts require
specified tightening torque, oil, grease or a
locking agent during assembly.

'-2 GENERAL INFORMATION
Before Servicing
Before starting to service a vehicle, careful reading of the applicable section is recommended to
eliminate unnecessary work. Photographs, diagrams, notes, cautions, warnings, and detailed des-
criptions have been included wherever necessary. Nevertheless, even a detailed account has limi-
tations, a certain amount of basic knowledge is also required for successful work.
Especially note the following:
(1) Dirt
Before removal and disassembly, clean the vehicle. Any dirt entering the engine or - other
parts will work as an abrasive and shorten the life of the vehicle. For the same reason, before
installing a new part, clean off any dust or metal filings.
(2) Battery Ground
Remove the ground (-) lead from the battery before performing any disassembly operations
on the vehicle. This prevents:
(a) the possibility of accidentally turning the engine over while partially disassembled.
(b) sparks at electrical connections which will occur when they are disconnected.
(c) damage to electrical parts.
(3) Tighten ing 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 evenly in a cross pattern. This is to avoid
distortion of the part and/or causing gas or oil leakage. Conversely when .loosening the bolts,
nuts, or screws, first loosen all of them by about a quarter of turn and then remove them.
Where there is a tightening sequence indication in this Service Manual, the bolts, nuts, or
screws must be tightened in the order and method indicated.
(4) Torque
When torque values are given in this Service Manual, use them. Either too little or too much
torque may lead to serious damage. Use a good quality, reliable torque wrench.
(5) Force
Common sense should dictate how much force is necessary in assembly and disassembly. If a
part seems especially difficult to remove or install, stop and examine what may be causing the
problem. Whenever tapping is necessary, tap lightly using a wooden or plastic-faced mallet. Use
an impact driver for screws (particularly for the removal of screws held by a locking agent) in
order to avoid damaging the screw heads.
(6) Edges
Watch for sharp edges, especially during major engine disassembly and assembly. Protect your
hands with gloves or a piece of thick cloth when lifting the engine or turning it over.
(7) High-Flash Point Solvent
A high-flash point solvent is recommended to reduce fire danger. A commercial solvent com-
monly available in North America is Stoddard solvent (generic name). Always follow manufac-
turer and container directions regarding the use of any solvent.
(B) Gasket, O-Ring
Do not reuse a gasket or O-ring once it has been in service. The mating surfaces around the
gasket should be free of foreign matter and perfectly smooth to avoid oil or compression leaks.
(9) Liquid Gasket, Non-Permanent Locking Agent
Follow manufacturer's directions for cleaning and preparing surfaces where these compounds
will be used. Apply sparingly. Excessive amounts may block engine oil passages and cause
serious damage. An example of a non-permanent locking agent commonly available in North
America is Loctite Lock'n Seal (Blue) .
(10) Press
A part installed using a press or driver, such as a wheel bearing, should first be coated with oil
on its outer or inner circumference so that it w ill go into place smoothly .
(11) Ball Bearing
When installing a ball bearing, the bearing race which is affected by friction should be pushed
by a su itable driver. This prevents severe stress on the balls and races, and prevents races and
balls from being dented . Press a ball bearing until it stops at the stop in the hole or on the shaft.

GENERAL INFORMATION 1-3
(12) Oil Seal and Grease Seal
Replace any oil or grease seals that were removed with new ones, as removal generally damages
seals.
When pressing in a seal which has manufacturer's marks, press it in with the marks facing out.
Seals should be pressed into place using a suitable driver, which contacts evenly with the side of
seal, until the face of the seal is even with the end of the hole.
(13) Seal Guide
A seal guide is required for certain oil or grease seals during installation to avoid damage to the
seal lips. Before a shaft passes through a seal, apply a little high temperature grease on the lips to
reduce rubber to metal friction.
(14) Circlip, Retaining Ring
Replace any circlips and retaining rings that were removed with new ones, as removal weakens
and deforms them. When installing circlips and retaining rings, take care to compress or expand
them only enough to install them and no more.
(15) Lubrication
Engine wear is generally at its maximum wh il e the engine is warming up and before all the
rubbing surfaces have an adequate lubricative film. During assembly, oil or grease (whichever is
more suitable) should be applied to any rubbing surface which has lost its lubricative film. Old
grease and dirty oil should be cleaned off . Deteriorated grease has lost its lubricative quality and
may contain abrasive foreign particles.
Don't use just any oil or grease. Some oils and greases in particular should be used only in
certain applications and may be harmful if used in an application for which they are not intended.
This manual makes reference to molybdenum disulfide grease (MoS,) in the assembly of certain
engine and chassis parts. Always check manufacturer recommendations before using such special
lubricants.
(16) Electrical Wires
All the electrical wires are either single- color or two-color and, with only a few exceptions,
must be connected to wires of the same color. On any of the two - color wires there is a greater
amount of one color and a lesser amount of a second color, so a two·color wire is identified by
first the primary color and then the secondary color. For example, a yellow wire with thin red
stripes is referred to as a "yellow/red" wire; it would be a "red/yellow" wire if the colors were
reversed to make red the main color.

(17) Replacement Parts
When there is a replacement instruction, replace these parts with new ones every time they are
removed. These replacement parts will be damaged or lose their original function once removed.
(18) Inspection
When parts have been disassembled, visually inspect these parts for the following conditions or
other damage. If there is any doubt as to the condition of them, replace them with new ones.
Abrasion Crack Hardening Warp
Bent Dent Scratch Wear
Color change Deterioration Seizure
(19) Specifications
Specification terms are defined as follows.
"Standards" show dimensions or performances which brand-new parts or systems have.
"Service limits" indicate the usable limits. If the measurement shows excessive wear or dete-
riorated performance, replace the damaged parts.
