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 m otor 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 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 R ECOMMEND THAT ALL DEALERS OBSERVE THESE PROVISIONS OF F EDERAL 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 i ncorporated 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 M aintenance 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
Special Tool Catalog or 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.

1-2 G ENERAL 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.
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 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 G ENERAL 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 c an 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. Rem ove 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 G asket 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 removal is necessary. Replace with new ones w henever 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 G ENERAL INFORMATION
Before Servicing
Direction o f 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.

The following tables list the tightening torque
for the major fasteners requiring use of a non
-permanent locking agent or liquid gasket.
Letters used in the “Remarks” column mean:
G: Apply grease to the threads.
EO: Apply engine oil to the threads and the
seating surface.
L: Apply a non-permanent locking agent to
the threads.
Lh: Left-hand threads.
MO: Apply molybdenum disulfide oil to the
threads and the seating surface. The molybdenum disulfide oil is a mixture of engine oil and molybdenum disulfide grease w ith a w eight ratio (10 : 1).
S: Tighten the fasteners following the speci-
fied sequence.
SS: Apply silicone sealant.
St: Stake the fasteners to prevent loosening.
