EMISSION CONTROL INFORMATION
Property of www.SmallEngineDiscount.com - Not for Resale
Toprotect the environment in which we all live, Kawasaki hasincorporated crankcaseemission
(1) and exhaust emission (2) control systems in compliance with applicable regulations of the
United States Environmental Protection Agency and California Air Resources Board.
1. Crankcase Emission Control System
A sealed-type crankcase emission control system isused to eliminateblow-by gases. The blow
-by gases are led to the breather chamber through the crankcase. Then, it is led to the air cleaner.
Oil is separated from the gases while passing through the inside of the breather chamber from
the crankcase, and then returned back to the bottom of the crankcase.
2. Exhaust Emission Control System
The exhaust emission control system applied to this engine family is engine modifications that
consist of a modifiedcarburetor andignition system having optimum ignitiontiming characteristics.
The carburetor has been calibrated to provide lean air/fuel mixture characteristics and optimum
fuel economy with a suitable air cleaner and exhaust system.
A maintenance free ignition system provides the most favorable ignition timing and helps main-
tain a thorough combustion process within the engine whichcontributes to a reduction of exhaust
pollutants entering the atmosphere.
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 repairi ng, servicing, selling, leasing, or trading
motor v ehicles or motor vehicle engines, or who operates a fleet of motor v ehicles 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..."
(Continued on next page.)
NOTE
Property of www.SmallEngineDiscount.com - Not for Resale
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 vehicle.
c.Addition ofcomponents or accessories thatresult in the vehicleexceeding 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.
PLEASE DO NOT TAMPER WITH NOISE CONTROL SYSTEM
(US Model only)
To minimize the noise emissions from this product, Kawasaki has equipped it with effective
intake and exhaust silencing systems. They are designed to give optimum performance while
maintaining a low noise level. Please do not remove these systems, or alter them in any way
which results in an increase in noise level.

Before Servicing
Before starting to perform an inspection service or carry out a disassembly and reassembly operation on a vehicle, 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 vehicle, disconnect
thebattery wires from thebattery 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
otherforeign materialsentering intosealed areasduring vehicle 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.
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 partsmay lead toserious accident. Visuallyinspect removed parts for corrosion, discoloration, or other damage. Refer to the appropriate sections
of this manual for s ervice limits on individualparts. Replace
the parts if any damage has been found or if the part is beyond its service limit.

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 thespecified sequence to prevent case warpage or deformationwhich 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.
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 orhard 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 old gaskets and c lean 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
Non-Permanent 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
Property of www.SmallEngineDiscount.com - Not for Resale
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
Donot remove pressedoil or greaseseals unless removal
is necessary. Replace with new ones whenever removed.
Press new oil sealswith manufacture andsize marks facing
out. Make sure the seal is aligned properlywhen installing.
Apply specified grease to the lip of seal before installing
the seal.
Circlips, Cotter Pins
Replacecirclips or cotterpins that wereremoved with new
ones. Take care not to open the clip excessively when installing to prevent deformation.
