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 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 cranckcase 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 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 repairing, servicing, selling, leasing, or trading
motor vehicles or motor vehicle engines, or who operates a fleet of motor vehicles know-
ingly 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 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.

1-2 GENERAL INFORMATION
Before Servicing
Before starting to service a motorcycle, careful reading of the applicable section is recommended to
eliminate unnecessary work. Photographs, diagrams, notes, cautions, warnings, and detailed descrip-
tions have been included wherever necessary. Nevertheless, even a detailed account has limitations,
a certain amount of basic knowledge is also required for successful work.
Especially note the following:
(1) Dirt
Before removal and disassembly, clean the motorcycle. Any dirt entering the engine or other
parts will work as an abrasive and shorten the life of the motorcycle. For the same reason, before
installing a new part, clean off any dust or metal filings.
(2) Battery Cables
Disconnect the ground (–) cable from the battery before performing any disassembly operations
on the motorcycle. This prevents the engine from accidentally turning over while work is being
carried out, sparks from being generated while disconnecting the leads from electrical parts, as
well as damage to the electrical parts themselves. For reinstallation, first connect the positive
cable to the positive (+) terminal of the battery.
(3) Installation, Assembly
Generally, installation or assembly is the reverse of removal or disassembly. But if this Service
Manual has installation or assembly procedures, follow them. Note parts locations and cable,
lead, and hose routing during removal or disassembly so they can be installed or assembled in
the same way. It is preferable to mark and record the locations and routing as much as possible.
(4) 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 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 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.
(5) 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.
(6) 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.
(7) 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.
(8) 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 manufacturer
and container directions regarding the use of any solvent.
(9) 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 leakage.
(10)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 seri-
ous damage. An example of non-permanent locking agent commonly available in North America
is Loctite Lock’n Seal (Blue).
(11)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 will go into place smoothly.

Before Servicing
(12)Ball Bearing and Needle Bearing
Do not remove a ball bearing or a needle bearing unless it is absolutely necessary. Replace
any ball or needle bearings that were removed with new ones, as removal generally damages
bearings. Install bearings with the marked side facing out applying pressure evenly with a suitable
driver. Only press on the race that forms the press fit with the base component to avoid damaging
the bearings. This prevents severe stress on the balls or needles and races, and prevent races
and balls or needles from being dented. Press a ball bearing until it stops at the stopper in the
hole or on the shaft.
(13)Oil Seal and Grease Seal
Replace any oil or grease seals that were removed with new ones, as removal generally dam-
ages 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. Before a shaft passes
through a seal, apply little high temperature grease on the lips to reduce rubber to metal friction.
(14)Circlip, Retaining Ring, and Cotter Pin
Replace any circlips and retaining rings, and cotter pins 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 while 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 (MoS2) and molybdenum disulfide
oil in the assembly of certain engine and chassis parts. The molybdenum disulfide oil is a mixture
of engine oil and molybdenum disulfide grease with a weight ratio (10 : 1), which can be made in
your work shop. Always check manufacturer recommendations before using such special lubri-
cants.
(16)Electrical Leads
All the electrical leads are either single-color or two-color and, with only a few exceptions, must
be connected to leads of the same color. On any of the two-color leads there is a greater amount
of one color and a lesser amount of a second color, so a two-color lead is identified by first the
primary color and then the secondary color. For example, a yellow lead with thin red stripes is
referred to as a "yellow/red" lead; it would be a "red/yellow" lead 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.

Before Servicing
(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.
(20)Instrument
Use a meter that has enough accuracy for an accurate measurement.
Read the manufacturer’s instructions thoroughly before using the meter.
Incorrect values may lead to improper adjustments.

Technical Information - KAWASAKI LOW EXHAUST EMISSION SYSTEM
Since the emission regulations become more severe, Kawasaki has adopted a type of simplified
KAWASAKI LOW EXHAUST EMISSION SYSTEM (KLEEN), which have no catalyst protection sys-
tem, according to each regulation of different countries.
The muffler with built-in catalyst has the same durability as the conventional muffler, however, do
not use leaded gasoline and do not coast with the ignition system OFF. Running the engine without
ignition damages catalyst.
Refer to 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 muffler body.
○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 the exhaust gas is diluted with the secondary air injection, the catalytic converter works well
because of rich oxygen to reduce CO, HC, and NOx. Accordingly, 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 NOx than the pipe type catalytic converter because of its more and denser catalysts.

Technical Information - Monocoque Frame
Why a monocoque? Like all breakthrough innovations, the choice appears quite obvious after the
fact. When large-section aluminium spars are wrapped around an already wide, large-displacement
in-line Four engine, the resulting package must of necessity be wide. The ZX-12R’s all-aluminium box
-section monocoque chassis eliminates these perimeter spars in favor of a large box section running
over the top of the engine.
This frame design surpasses the levels of chassis stiffness and strength associated with conven-
tional aluminium twin-beam frames, but with considerably less breadth. Without the twin beams or
other frame elements running around the side of the engine, the fairing can be much narrower, re-
sulting in a much slimmer overall package and significantly better aerodynamics. Further, in a radical
departure, the hollow structure also doubles as an airbox for the Ram Air system, eliminating the need
for a space-consuming, conventional airbox.
And ultimately, it is the synergy of combining a compact, massively powerful engine with this super
stiff and slim chassis structure that explains much of the ZX-12R’s superlative high-speed perfor-
mance.
•All-new frame-integrated Ram Air system adds consider-
able horsepower in the higher speed ranges.
•Monocoque frame allows for the use of perfectly straight,
highly efficient inlet ports.
•Using the frame backbone as an airbox saves space and
creates a very efficient airbox.
•Battery mounts inside the frame and the battery cover is
a structural element.
•Revolutionary new all-aluminum monocoque frame for
high rigidity and lightweight.
•Huge box section and heat-freated cast steering
head/swingarm pivot areas realize an extremely
stiff structure and contribute to the ZX-12R’s superb
high-speed stability and nimble, super sport handling
performance.
•By eliminating the dual large-section beams of conven-
tional aluminum frames, this frame design makes possi-
ble a much narrower and more compact overall package
and greatly improves aerodynamics.

Technical Information - Spark Plug
ZX1200-B is equipped with the Kawasaki recommended
spark plug (NGK CR9EKPA). By using the Kawasaki rec-
ommended spark plug, the idling stability, the fuel consump-
tion improvement, and the maintenance free spark plug is
planed.
This spark plug is calculated 3 or 4 times as durable as
the usual one (NGK CR9EK).
Feature
1. This spark plug is more superior to the usual one with
the ignition for the ignition point protruding.
2. Further, this spark plug is superior to the usual one with
the endurance for the Pt alloy [A] covering around the
center electrode and for the opposed area improvement
of the side electrodes.
Specification
1. Standard Spark Plug CR9EKPA, two side electrodes,
M10 threads
2. Hotter Spark Plug CR8EKPA, two side electrodes, M10
threads
CAUTION
Use only the recommender spark plug. Do not use
other spark plug, even though it may fit, because it
could cause the engine failure of the idling stability,
etc.

Technical Information - Immobilizer System (ZX1200-B3 ∼: Equipped Model)
Overview
This system provides a theft proof device by means of matching a code between the inbuilt key
transponder and the ECU (Electronic Control Unit). If this code does not match, the fuel pump, injec-
tors, ignition system and sub-throttle valve actuator will not operate and the engine will not start.

Connector
Master Key (1 piece)
The master key (colored red) has an inbuilt transponder, containing a master key code. These
codes are unique to each key. This code and an additional two user key codes must be registered
in the ECU for the system to operate. The master key is necessary when registering user keys and
should not be used as the main key to start the motorcycle except in emergencies (loss or damage of
user keys). It should be kept in a safe place.

Transponder (in Keys)
The transponder (made by Texas Instruments, Inc.) has an integrated circuit with a unique code
that also calculates data sent by the ECU. When the ignition switch is turned ON, the transponder
is excited by the radio wave transmitted from the antenna and then transmits a unique code to the
antenna.
User Key (2 pieces)
The user keys (colored black) should be used when riding the motorcycle. These keys have unique
codes which differ from the master key. Up to a maximum of five user key codes can be stored by
the ECU at any one time. These codes can not be registered to the ECU without firstly registering the
master key code.
Antenna
The antenna transmits a radio wave to excite the transponder, receives the code from the transpon-
der and then transmits the code to the ECU through the amplifier.
Ignition Switch
The ignition switch turns the main circuit ON and OFF.
Amplifier
The amplifier (which is approximately the same size as a match box), amplifies signals from the
antenna and the ECU.
ECU
The ECU has the capacity to store a maximum of six key code memories (one master and five user
keys). The owner can have a total of five user keys at any one time. The master key memory can not
be rewritten after initial registration, whereas the user key memories can be rewritten as necessary.
When the ECU communicates with the transponder, a cipher generator changes the code every time
it is used to avoid cloning.
FI Indicator Light
The condition or the failure of the immobilizer system is indicated by various patterns of the FI indi-
cator light blinking.
1. Immobilizer Amplifier
2. Immobilizer Antenna
3. Ignition Switch
4. Meter Unit
5. FI Indicator Light
6. Ignition Fuse 10 A
7. ECU Fuse 15 A
8. Junction Box
9. ECU Main Relay
10. Starter Relay
11. Main Fuse 30 A
12. Battery 12 V 12 Ah
13. Immobilizer/Kawasaki Diagnostic System
Connector
14. Electronic Control Unit (ECU)

Sequence of Operation
1. Turn ON the ignition switch, the ECU, amplifier and antenna start working, and the meter assembly
FI indicator lights up.
2. The transponder excited by radio waves transmitted from the antenna receives the ciphered code
from the ECU.
3. The transponder transmits the calculated result from the key’s unique code to the ECU.
4. The ECU compares this with its memorized code, and if they match the engine can start. At this
time, the FI indicator in the meter assembly is switched off.

Torque and Locking Agent
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:
L: Apply a non-permanent locking agent to the threads.
M: Apply molybdenum disulfide grease.
MO: Apply molybdenum disulfide oil solution.
O: Apply oil to the threads and seating surface.
S: Tighten the fasteners following the specified sequence.
SS: Apply silicone sealant.
St: Stake the fasteners to prevent loosening.
R: Replacement Parts
The table below, relating tightening torque to thread diameter, lists the basic torque for the bolts and
nuts. Use this table for only the bolts and nuts which do not require a specific torque value. All of the
values are for use with dry solvent-cleaned threads.
