Foreword
This manual is designed primarily for use by
trained mechanics in a properly equipped shop.
However, it contains enough detail and basic in-
formation to make it useful to the owner who de-
sires to perform his own basic maintenance and
repair work. A basic knowledge of mechanics,
the proper use of tools, and workshop proce-
dures must be understood in order to carry out
maintenance and repair satisfactorily. When-
ever the owner has insufficient experience or
doubts his ability to do the work, all adjust-
ments, maintenance, and repair should be car-
ried 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 care-
fully 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 ad-
versely affect safe operation.
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 Mo-
torcycle parts. Special tools, gauges, and
testers that are necessary when servicing
Kawasaki motorcycles are introduced by the
Service Manual. Genuine parts provided as
spare parts are listed in the Parts Catalog.
•
Follow the procedures in this manual care-
fully. 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 this manual, the product is divided into

ble of Contents.
For example, if you want ignition coil informa-
tion, use the Quick Reference Guide to locate
the Electrical System chapter. Then, use the
Table of Contents on the first page of the chap-
ter to find the Ignition Coil section.
Whenever you see symbols, heed their in-
structions! Always follow safe operating and
maintenance practices.

ticular interest for more efficient and con-
venient operation.

ified tightening torque, oil, grease or a locking
agent during assembly.

1-2 GENERAL INFORMATION
Before Servicing
Before starting to perform an inspection service or carry out a disassembly and reassembly opera-
tion on a motorcycle, read the precautions given below. To facilitate actual operations, notes, illustra-
tions, 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:
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 ve-
hicle disassembly can cause excessive wear and decrease
performance of the vehicle.
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.
