EMISSION CONTROL INFORMATION
To protect the environment in which we all live, Kawasaki has incorporated crankcase emis-
sion (1
) and exhaust emission (2) control systems in compliance with applicable regulations of
the United States Environmental Protection Agency and California Air Resources Board. Addi-
tionally, Kawasaki has incorporated an evaporative emission control system (3) in compliance
with a
pplicable regulations of the California Air Resources Board on vehicles sold in California
only.
1. Crankcase Emission Control System
This s
ystem eliminates the release of crankcase vapors into the atmosphere. Instead, the vapors
are routed through an oil separator to the intake side of the engine. While the engine is operating,
the vapors are drawn into combustion chamber, where they are burned along with the f uel and air
suppl
ied 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 th
is 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 m otorcycle manufactured primarily for sale in California includes
acat
alytic converter system.
3. Evaporative Em ission Control System
Vapors caused by fuel evaporation in the fuel system are not vented into the atmosphere. In-
ste
ad, 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
com
monly 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 o
r 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 m anufacturer or dealer
knowingly to remove or render inoperative any such device or element of design after such
sal
e 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 know-
ing
ly 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 follow-
ing 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 de-
vices 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 dura bility 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 RECO MMEND 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 i ts 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.

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.
Espec
ially note the following:
Battery Ground
Before completing any service on the motorcycle, discon-
nect t
he 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
servi
ce, first connect the positive (+) wire to the positive (+)
terminal of the battery then the negative (−) wire to the neg-
ative 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 ve-
hicle disassembly can cause excessive wear and decrease
performance of the vehicle.
GENERAL INFORMATION 1-3
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.
Inspection
Reuse of worn or damaged parts may lead to serious ac-
cident. Visually inspect removed parts for corrosion, discol-
oration, 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 be-
yond its service limit.
Replacement Parts
Replacement Parts must be KAWASAKI genuine or rec-
ommended 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 disassem-
bly, however, if assembly order is provided in this Service
Manual, follow the procedures given.
1-4 GENERAL INFORMATION
Before Servicing
Tightening Sequence
Bolts, nuts, or screws must be tightened according to the
specif
ied sequence to prevent case warpage or deformation
which can lead to malfunction. If the specified tightening
sequence is not indicated, tighten the fasteners alternating
diago
nally.
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 or hard to repair dam-
age. 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, Oring
Hardening, shrinkage, or damage of both gaskets and
grease seals after disassembly can reduce sealing perfor-
mance. Remove old gaskets and clean the sealing surfaces
thoroughly so that no gasket material or other material re-
mains. Install new gaskets and replace used grease seal
when re-assembling
Liquid Gasket, Locking Agent
For applications that require Liquid Gasket or a Locking
agent, clean the surfaces so that no oil residue remains be-
fore applying liquid gasket or locking agent. Do not apply
them excessively. Excessive application can clog oil pas-
sages and cause serious damage.
GENERAL INFORMATION 1-5
Before Servicing
Press
For items such as bearings or oil seals that must be
pressed into place, apply small amount of oil to the con-
tact 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.
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.
Circlips, Cotter Pins
Replace circlips or cotter pins t hat 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. Lubri-
cation points are called out throughout this manual, apply
the specific oil or grease as specified.
1-6 GENERAL INFORMATION
Before Servicing
Direction of Engine Rotation
When rotating the crankshaft by hand, the free play
amount
of rotating direction will affect the adjustment. Ro-
tate 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.

Technical Information – Air Inlet System
Subthrottle Control System
The ZR 1000–A1 ∼ employs large bore throttle bodies to increase power output. However, sudden
changes in throttle opening can cause hesitation and jerky throttle response with a single butterfly
valve in a large bore. Therefore two throttle valves are placed in each i nlet tract, the main throttle
valve located closest to the cylinder and a subthrottle valve placed further up the inlet tract. The main
throttle valve is operated by the rider when the throttle grip is turned clockwise or counterclockwise,
while the subthrottle valve is operated by a stepping motor controlled by the ECU. The subthrottle
valve automatically adjusts air inlet to more precisely match engine demand, so that when the main
throttle is opened quickly there is no hesitation or j erky response.
The subthrottle valves allow the fuel injection system to provide smooth t hrottle response, similar to
that of a constant velocity carburetor, no matter how quickly the throttle is opened.

Technical Information – Air Inlet System
Operation
The subthrottle control system consists of the subthrottle valve, subthrottle valve actuator with a
steppi
ng motor built in it, ECU, and subthrottle sensor. The subthrottle valve is built in the each throttle
body.
The subthrottle control system operates on the signal supplied from the ECU. The open/close oper-
ation o
f the subthrottle valve is performed by the subthrottle actuator which is controlled by the ECU
to change the current direction into the motor of the subthrottle valve actuator.
The subthrottle sensor detects the subthrottle valve actuator movement by measuring voltage and
the EC
U determines the subthrottle valve angle based on the operation map.
When turning the ignition switch ON, every time the ECU automatically drives the subthrottle valve
from fully closed position to fully opened position. The ECU memorizes these positions and turns
back t
he subthrottle valve to the original point to confirm the subthrottle valve idling voltage.

Technical Information – Tail/Brake Lights Employing LED
Outline
This model employs a tail/brake light containing 21 Light Emitting Diodes (LED). The LED emits
lumino
us beams over a longer life span than those emitted from a traditional electric heated bulb
(more than 5 times longer), uses lower voltage, expends lower wattage (approx.1/5), and is quicker
responsing.
Due Position of LED Installation
The r
esistors, the diodes, and the Zener diodes are
mounted in the electronic circuits [A] of the LED, which
supplies the steady current and voltage to the light.
Light Emitting Diode (LED)
The Light Emitting Diode (LED) [A] is an element of semi-
conductor diode that converts applied voltage to light.
The LED emits luminous beams by the collision of nega-
tive charge electrons [A] and positive charge holes [B] when
applied the forward voltage and current to the PN junction
diode [C].

Technical Information - KLEEN (KAWASAKI LOW EXHAUST EMISSION SYSTEM)
Since the emission regulations become more severe, Kawasaki has adopted a type of simplified
KLEEN, which have no catalyst protection system, according to each regulation of different countries.
The muf
fler with built-in catalyst has the same durability as the conventional muffller, however, do
not use leaded gasoline and do not coast with the ignition system OFF. Running the engine without
ignition damages catalyst.
Refer t
o the ZX900E Service Manual (Part No. 99924-1255) for more information about the KLEEN
(theory, maintenance, and handling precautions), including the secondary air injection system.
Honeycomb Type Catalytic Converter
○
The converter is a three-way catalytic converter, and its surface is covered with alumina upon which
platinum and rhodium are applied, and has a cylindrical metalic honeycomb structure made by bend-
ing a corrugated sheet and a flat sheet of stainless steel into a spiral of increasing diameter. The
honeycomb structure is convenient for the catalytic converter because it has a large surface area
but small size to react effectively and has low exhaust resistance. In addition, its inherent strength
helps resist vibration, and has simple structure welded directly on the silencer.
○
Generally, the temperature of the exhaust gas must be higher than activation temperature, so the
converters are installed in the exhaust manifold rear end where the temperature of exhaust gas is
still high. And, the converters will be activated even under low load conditions.
○
After t he exhasut gas is diluted with the secondary air injection, the catalytic converter works well
because of rich oxygen to reduce CO, HC, and NO
x. A ccordingly, we can keep the exhaust gas
emission within regulation.
○
This type of converter works more efficiently as a three-way catalytic converter to reduce CO, HC,
and NO
x than the pipe type catalytic converter because of its more and denser catalysts.
