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 cranckcase vapors into the atmosphere. Instead, the

vapors are routed through an oil separator to the inlet side of the engine. W hile 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 f leet of m otor 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 a s follows :

1. Tampering does not include the temporary removal or rendering inoperative of de­vices or elements of design in o rder 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 RECOMMEND THAT ALL DEALERS OBSERVE THESE PROVISIONS OF FEDERAL 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 incorporated 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.

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 descrip­tions 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 f rom 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 m ay 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 com­monly 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 seri­ous 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.

GENERAL INFORMATION 1-3

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 dam­ages 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 w ith 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 (MoS
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 lubri­cants.

(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 .

2) and molybdenum disulfide

(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.

1-4 GENERAL INFORMATION

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 SYS TEM

Since the emission regulations become more severe, Kawasaki has adopted a type of simplified
KAWASAKI LOW EX HAUST EMISSION SYSTEM (KLEEN), which have no catalyst protection sys­tem, 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 silencer.

Generally, the temperature of t he 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 NO

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.

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 conven­tional 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, re­sulting 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 perfor­mance.

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, s uper 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-B1 is equipped with the Kawasaki recommended
spark plug (NGK CR9EKPA). By using the Kawasaki recom­mended spark plug, the i dling stability, the fuel consump­tion 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 t o 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

GENERAL INFORMATION 1-13

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.

1-14 GENERAL INFORMATION

Technical Information – Immobilizer System (ZX1200-B3)

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 t his code does not match, the fuel pump, injec­tors, ignition system and sub-throttle valve actuator will not operate and the engine will not start.

Related Parts and Function

1. Transponder (Inside Keys)

2. Master Key

3. User Keys

4. FI Indicator Light

5. Immobilizer Antenna

6. Ignition Switch

7. Immobilizer Amplifier

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

Technical Information – Immobilizer System (ZX1200-B3)

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 c ode.

Antenna

The antenna transmits a radio wave to excite the transponder, receives the code from the t ranspon­der 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 indi­cator light blinking.

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 com pares 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 Lo cking 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.
