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 includes a catalytic converter system.
3. Evaporative Emission Control System
Vapors caused by fuel evaporation in the fuel system are not vented into the atmosphere. Instead, 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 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 exceeded.
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 standards.
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.
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 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 cables from the battery to prevent the engine from accidentally turning over. Disconnect the ground
cable (–) first and then the positive (+). When completed
with the service, first connect the positive (+) cable to the
positive (+) terminal of the battery then the negative (–) cable 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.
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 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 GENERAL INFORMATION
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 the specified sequence to prevent case warpage or deformation which 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.
Force
Use common sense during disassembly and assembly,
excessive force can 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.
Remove old gaskets and clean the sealing surfaces thoroughly so that no gasket material or other material remains.
Install the new gaskets and replace the used O-rings when
re-assembling.
Liquid Gasket, Non-permanent 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
non-permanent locking agent. Do not apply them excessively. Excessive application can clog oil passages 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 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.
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.
Apply specified grease to the lip of seal before installing
the seal.
Circlips, Cotter Pins
Replace the circlips or cotter pins that were removed with
new ones. Take care not to open the clip excessively when
installing to prevent deformation.
1-6 GENERAL INFORMATION
Before Servicing
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.
Direction of 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.
Instrument
Use a meter that has enough accuracy for an accurate
measurement. Read the manufacture’s instructions thoroughly before using the meter. Incorrect values may lead
to improper adjustments.

1-12 GENERAL INFORMATION
Technical Information-KIMS (Kawasaki Ignition Management System)
Overview
This motorcycle is equipped with the Kawasaki ignition management system which was developed
as a rider aid for track riding using technology borrowed from racing machines. Experienced racers
or track riders can deliberately cause wheel spin to occur when exiting mid/high speed corners. However, they rely on precise throttle control to maintain the optimum acceleration level without sacrificing
too much wheel spin. KIMS was designed to aid such riding where precise throttle control is required.
This system has not been developed to eliminate all wheel spin, as there are times when this can
be advantageous for experienced riders, and too much control would lead to a very sterile riding experience.
Operation
In addition to normal DFI activity the ECU’s
complex programme monitors throttle opening,
vehicle speed, gear position, and the rate of
change of engine speed.
When the ECU detects the rear wheel is
slipping by a sudden change in engine speed,
the previously mentioned factors are calculated and within certain parameters the ignition
timing is retarded to reduce excessive engine
speed. The number of degrees that the ECU
retards the ignition is determined by continuous sampling, with the aim being to optimize
the relationship between throttle opening, engine/vehicle speed and ultimately ensuring the
optimum combination of grip/acceleration.
To ensure that this system does not act unnecessarily, the following situations are taken into account.
1. This system does not act at idle speed, small throttle openings, or at full throttle.
2.
In cases of snapping open the throttle with the
clutch half-engaged (example [A]), the system
compares the gear position, engine speed
and the vehicle speed to determine whether
or not to engage. This system does not act
when the clutch is at the partially disengaged
or slipping.
3. This system does not act on sudden throttle openings.

“L”: Low
“F”: Full
CAUTION
For refilling, add the specified mixture of coolant
and soft water. Adding water alone dilutes the
coolant and degrades its anticorrosion properties.
The diluted coolant can attack the aluminum engine parts. In an emergency, soft water alone can
be added. But the diluted coolant must be returned
to the correct mixture ratio within a few days.
If coolant must be added often or the reservoir tank
has run completely dry, there is probably leakage in
the cooling system. Check the system for leaks.
Coolant ruins painted surfaces. Immediately wash
away any coolant that spills on the frame, engine,
wheels or other painted parts.
Radiator Hose and Pipe Inspection (coolant leak,
damage, installation condition)
○The high pressure inside the radiator hose can cause

are noticed.
Check that the hoses are securely connected and clamps
are tightened correctly.

Maintenance Procedure
CAUTION
Be sure to remeasure the clearance after selecting
a shim. The clearance can be out of the specified
range because of the shim tolerance.
○If there is no valve clearance, use a shim that is a few
•
sizes smaller, and remeasure the valve clearance.
When installing the shim, face the marked side toward the
valve lifter. At this time, apply engine oil to the shim or
the valve lifter to keep the shim in place during camshaft
installation.
CAUTION
Do not put shim stock under the shim. This may
cause the shim to pop out at high rpm, causing extensive engine damage.
Do not grind the shim. This may cause it to fracture,
causing extensive engine damage.

Visually inspect the wheel for cracks, cuts and dents damage.
If any damage is found, replace the wheel if necessary.
Tire Tread Wear Inspection
As the tire tread wears down, the tire becomes more susceptible to puncture and failure. An accepted estimate is
that 90% of all tire failures occur during the last 10% of tread
life (90% worn). So it is false economy and unsafe to use
the tires until they are bald.
Measure the tread depth at the center of the tread with a
depth gauge [A]. Since the tire may wear unevenly, take
measurement at several places.
If any measurement is less than the service limit, replace
the tire (see Tire Removal/Installation in the Wheels/Tires
chapter).

DFI Servicing Precautions
DFI Servicing Precautions
There are a number of important precautions that should
be followed servicing the DFI system.
○This DFI system is designed to be used with a 12 V sealed
battery as its power source. Do not use any other battery
except for a 12 V sealed battery as a power source.
○Do not reverse the battery cable connections. This will
damage the ECU.
○To prevent damage to the DFI parts, do not disconnect the
battery cables or any other electrical connections when
the ignition switch is on or while the engine is running.
○Take care not to short the leads that are directly connected to the battery positive (+) terminal to the chassis
ground.
○When charging, remove the battery from the motorcycle.
This is to prevent ECU damage by excessive voltage.
○Whenever the DFI electrical connections are to be dis-
connected, first turn off the ignition switch, and disconnect
the battery (–) terminal. Do not pull the lead, only the connector. Conversely, make sure that all the DFI electrical
connections are firmly reconnected before starting the engine.
○Connect these connectors until they click [A].
○Do not turn the ignition switch ON while any of the DFI
electrical connectors are disconnected. The ECU memorizes service codes.
○Do not spray water on the electrical parts, DFI parts, connectors, leads and wiring.
○If a transceiver is installed on the motorcycle, make sure
that the operation of the DFI system is not influenced by
electric wave radiated from the antenna. Check operation
of the system with the engine at idle. Locate the antenna
as far as possible away from the ECU.
○When any fuel hose is disconnected, do not turn on the
ignition switch. Otherwise, the fuel pump will operate and
fuel will spout from the fuel hose.
○Do not operate the fuel pump if the pump is completely
dry. This is to prevent pump seizure.
○Before removing the fuel system parts, blow the outer surfaces of these parts clean with compressed air.
○When any fuel hose is disconnected, fuel may spout out
by residual pressure in the fuel line. Cover the hose joint
with a piece of clean cloth to prevent fuel spillage.
○When installing the fuel hoses, avoid sharp bending, kinking, flattening or twisting, and route the fuel hoses with a
minimum of bending so that the fuel flow will not be obstructed.
○Run the hoses according to Cable, Wire, and Hose Routing section in the Appendix chapter.
○To prevent corrosion and deposits in the fuel system, do
not add to fuel any fuel antifreeze chemicals.
FUEL SYSTEM (DFI) 3-23
DFI Servicing Precautions
○If the motorcycle is not properly handled, the high pres-
sure inside the fuel line can cause fuel to leak or the hose
to burst. Remove the fuel tank (see Fuel Tank Removal)
and check the fuel hose.
Primary Fuel Hose [A]
Secondary Fuel Hose [B]
Replace the fuel hose if any fraying, cracks or bulges are
noticed.
○To maintain the correct fuel/air mixture (F/A), there must
be no inlet air leaks in the DFI system. Be sure to install
the oil filler plug [A] after filling the engine oil.
Torque - Oil Filler Plug: Hand-tighten
3-24 FUEL SYSTEM (DFI)
Troubleshooting the DFI System
The warning indicator light (LED) [A] is used for the FI
indicator, immobilizer indicator (equipped models) and oil
pressure warning indicator.
Outline
When a problem occurs with DFI system, the warning indicator light (LED) [A] and FI warning symbol [B] blinks to
alert the rider. In addition, the condition of the problem is
stored in the memory of the ECU. For models equipped with
an immobilizer system, the warning indicator light (LED)
and immobilizer warning symbol [C] blinks, when a problem occurs in the system.
With the engine stopped and turned in the self-diagnosis
mode, the service code [A] is displayed on the LCD (Liquid
Crystal Display) by the number of two digits.
If the problem is with the following parts, the ECU can not
recognize these problem. Therefore, the warning indicator
light (LED), FI and/or immobilizer warning symbols do not
blinks, and service code is not displayed.

Primary and Secondary Fuel Injectors
Stick Coil Secondary Wiring and Ground Wiring

FUEL SYSTEM (DFI) 3-25
Troubleshooting the DFI System
When the service code [A] is displayed, for first ask the
rider about the conditions [B] of trouble, and then start to
determine the cause [C] of problem.
As a pre-diagnosis inspection, check the ECU for ground
and power supply, the fuel line for no fuel leaks, and for
correct pressure. The pre-diagnosis items are not indicated
by the warning indicator light (LED) and FI warning symbol.
Don’t rely solely on the DFI self-diagnosis function, use
common sense.
Even when the DFI system is operating normally, the
warning indicator light (LED) and FI warning symbol may
blink under strong electrical interference. Additional measures are not required. Turn the ignition switch OFF to stop
the indicator light and symbol.
If the warning indicator light (LED) and FI warning symbol
of the motorcycle brought in for repair still blinks, check the
service code.
When the repair has been done, the FI warning symbol
goes off. But the service codes stored in memory of the
ECU are not erased to preserve the problem history. The
problem history can be referred using the KDS (Kawasaki
Diagnostic System) when solving unstable problems.
When the motorcycle is down, the vehicle-down sensor
operates and the ECU shuts off the fuel pump relay, fuel
injectors (primary and secondary) and ignition system. The
ignition switch is left ON. If the starter button is pushed, the
electric starter turns but the engine does not start. When the
starter button is pushed, the warning indicator light (LED)
and FI warning symbol blink but the service code is not
displayed. To start the engine again, raise the motorcycle,
turn the ignition switch OFF, and then ON.
Much of the DFI system troubleshooting work consists
of confirming continuity of the wiring. The DFI parts are
assembled and adjusted with precision, and it is impossible
to disassemble or repair them.
3-26 FUEL SYSTEM (DFI)
Troubleshooting the DFI System
checking the DFI parts, use a digital meter which
• When
can be read two decimal place voltage or resistance.
○The DFI part connectors [A] have seals [B], including the
ECU. When measuring the input or output voltage with the
connector joined, use the needle adapter set [C]. Insert
the needle adapter inside the seal until the needle adapter
reaches the terminal.

of a digital meter.
Be careful not to short-circuit the leads of the DFI or electrical system parts by contact between adapters.
Turn the ignition switch ON and measure the voltage with
the connector joined.
CAUTION
Incorrect, reverse connection or short circuit by
needle adapters could damage the DFI or electrical
system parts.
○After measurement, remove the needle adapters and ap-
ply silicone sealant to the seals [A] of the connector [B]
for waterproofing.

Trouble may involve one or in some cases all items.
Never replace a defective part without determining what
CAUSED the problem. If the problem was caused by
some other item or items, they too must be repaired or
replaced, or the new replacement part will soon fail again.
Measure coil winding resistance when the DFI part is cold
(at room temperature).
Make sure all connectors in the circuit are clean and tight,
and examine wires for signs of burning, fraying, short,
etc. Deteriorated wires and bad connections can cause
reappearance of problems and unstable operation of the
DFI system.
If any wiring is deteriorated, replace the wiring.

Check the wiring for continuity.
○Use the wiring diagram to find the ends of the lead which
is suspected of being a problem.
○Connect the hand tester between the ends of the leads.

Special Tool - Hand Tester: 57001-1394
○Set the tester to the × 1 Ω range, and read the tester.
If the tester does not read 0 Ω, the lead is defective. Replace the lead or the main harness or the subharness.
○If both ends of a harness [A] are far apart, ground [B] the
one end [C], using a jumper lead [D] and check the continuity between the end [E] and the ground [F]. This enables to check a long harness for continuity. If the harness
is open, repair or replace the harness.
○When checking a harness [A] for short circuit, open one
end [B] and check the continuity between the other end
[C] and ground [D]. If there is continuity, the harness has
a short circuit to ground, and it must be repaired or replaced.

tinuity tests from the ECU connectors.
If no abnormality is found in the wiring or connectors, the
DFI parts are the next likely suspects. Check the part,
starting with input and output voltages. However, there is
no way to check the ECU itself.
If an abnormality is found, replace the affected DFI part.
If no abnormality is found in the wiring, connectors, and
DFI parts, replace the ECU.

Note:
(1) α-N Method: the DFI control method from medium to heavy engine load. When the engine load
is light like at idling or low speed, the ECU determines the injection quantity by calculating from the
throttle vacuum (inlet air pressure sensor output voltage) and engine speed (crankshaft sensor output
voltage). This method is called D-J method. As the engine speed increases, and the engine load turns
middle to heavy, the ECU determines the injection quantity by calculating from the throttle opening
(main throttle sensor output voltage) and the engine speed. This method is called α-N method.
*: This depends on the number of stopped cylinders.

then
Pv = Pl – Pg
For example, suppose the following data is obtained:
Pg = 8 cmHg (Vacuum Gauge Reading)
Pl = 70 cmHg (Barometer Reading)
Vv = 3.2 V (Digital Meter Reading)
then
Pv = 70 – 8 = 62 cmHg (Absolute)
Plot this Pv (62 cmHg) at a point [1] on the chart and draw a
vertical line through the point. Then, you can get the usable
range [2] of the sensor output voltage.

This sensor has a weight [A] with two magnets inside,
and sends a signal to the ECU. But when the motorcycle
banks 60 ∼ 70° or more to either side (in fact falls down),
the weight turns and the signal changes. The ECU senses
this change, and stops the fuel pump relay, the fuel injectors
(primary and secondary) and the ignition system.

Permanent type antifreeze is used as a coolant to protect the cooling system from rust and corrosion.
When the engine starts, the water pump turns and the coolant circulates.
The thermostat is a wax pellet type which opens or closes with coolant temperature changes. The
thermostat continuously changes its valve opening to keep the coolant temperature at the proper level.
When coolant temperature is less than 55°C (131°F), the thermostat closes so that the coolant flow
is restricted through the air bleeder hole, causing the engine to warm up more quickly. When coolant
temperature is more than 58 ∼ 62°C (136 ∼ 144°F), the thermostat opens and the coolant flows.
When the coolant temperature goes up beyond 95°C (203°F), the radiator fan relay conducts to operate the radiator fan. The radiator fan draws air through the radiator core when there is not sufficient
air flow such as at low speeds. This increases up the cooling action of the radiator. When the coolant
temperature is below 90°C (194°F), the fan relay opens and the radiator fan stops.
In this way, this system controls the engine temperature within narrow limits where the engine operates most efficiently even if the engine load varies.
The system is pressurized by the radiator cap to suppress boiling and the resultant air bubbles
which can cause engine overheating. As the engine warms up, the coolant in the radiator and the
water jacket expands. The excess coolant flows through the radiator cap and hose to the reserve tank
to be stored there temporarily. Conversely, as the engine cools down, the coolant in the radiator and
the water jacket contracts, and the stored coolant flows back to the radiator from the reserve tank.
The radiator cap has two valves. One is a pressure valve which holds the pressure in the system
when the engine is running. When the pressure exceeds 93 ∼ 123 kPa (0.95 ∼ 1.25 kgf/cm², 13 ∼ 18
psi), the pressure valve opens and releases the pressure to the reserve tank. As soon as pressure
escapes, the valve closes, and keeps the pressure at 93 ∼ 123 kPa (0.95 ∼ 1.25 kgf/cm², 13 ∼ 18 psi).
When the engine cools down, another small valve (vacuum valve) in the cap opens. As the coolant
cools, the coolant contracts to form a vacuum in the system. The vacuum valve opens and allows the
coolant from the reserve tank to enter the radiator.

• Visually
If whitish cotton-like wafts are observed, aluminum parts
in the cooling system are corroded. If the coolant is
brown, iron or steel parts are rusting. In either case, flush
the cooling system.
If the coolant gives off an abnormal smell, check for a
cooling system leak. It may be caused by exhaust gas
leaking into the cooling system.

• Watch
If the pressure holds steady, the system is all right.
•
If the pressure drops and no external source is found,
check for internal leaks. Droplets in the engine oil indicate
internal leakage. Check the cylinder head gasket and the
water pump.
Remove the pressure tester, replenish the coolant, and

Cooling System Flushing
Over a period of time, the cooling system accumulates
rust, scale, and lime in the water jacket and radiator. When
this accumulation is suspected or observed, flush the cooling system. If this accumulation is not removed, it will clog
up the water passage and considerable reduce the efficiency of the cooling system.
Drain the cooling system (see Coolant Change in the Periodic Maintenance chapter).
Fill the cooling system with fresh water mixed with a flushing compound.

Do not use a flushing compound which is harmful to

CAUTION
This is a non-return type camshaft chain tensioner.
The push rod does not return to its original position
once it moves out to take up camshaft chain slack.
Observe all the rules listed below:
When removing the tensioner, do not take out the
mounting bolts only halfway. Retightening the
mounting bolts from this position could damage
the tensioner and the camshaft chain. Once the
bolts are loosened, the tensioner must be removed
and reset as described in "Camshaft Chain Tensioner Installation."

1. This valve seat cutter is developed to grind the valve for
repair. Therefore the cutter must not be used for other
purposes than seat repair.
2. Do not drop or shock the valve seat cutter, or the diamond particles may fall off.
3. Do not fail to apply engine oil to the valve seat cutter
before grinding the seat surface. Also wash off ground
particles sticking to the cutter with washing oil.
NOTE
○Do not use a wire brush to remove the metal particles
from the cutter. It will take off the diamond particles.
4. Setting the valve seat cutter holder in position, operate
the cutter in one hand. Do not apply too much force to
the diamond portion.
NOTE
○Prior to grinding, apply engine oil to the cutter and dur-
ing the operation, wash off any ground particles sticking
to the cutter with washing oil.
5. After use, wash it with washing oil and apply thin layer
of engine oil before storing.
Marks Stamped on the Cutter
The marks stamped on the back of the cutter [A] represent
the following.
60° ........................... Cutter angle [B]
37.5 ....................... Outer diameter of cutter [C]
Operating Procedures
Clean the seat area carefully.
Coat the seat with machinist’s dye.
Fit a 45° cutter into the holder and slide it into the valve
guide.
Press down lightly on the handle and turn it right or left.
Grind the seating surface only until it is smooth.
•
•
•
•
CAUTION
Do not grind the seat too much. Overgrinding will
reduce valve clearance by sinking the valve into the
head. If the valve sinks too far into the head, it will
be impossible to adjust the clearance, and the cylinder head must be replaced.

Original Seating Surface [B]
NOTE
○Remove all pittings of flaws from 45° ground surface.
○After grinding with 45° cutter, apply thin coat of machin-
ist’s dye to seating surface. This makes seating surface
distinct and 32° and 60° grinding operation easier.
○When the valve guide is replaced, be sure to grind with
45° cutter for centering and good contact.
If the outside diameter [A] of the seating surface is too
large, make the 32° grind described below.
If the outside diameter of the seating surface is within the
specified range, measure the seat width as described below.
Grind the seat at a 32° angle [B] until the seat O.D. is
within the specified range.
○To make the 32° grind, fit a 32° cutter into the holder, and
slide it into the valve guide.
○Turn the holder one turn at a time while pressing down
very lightly. Check the seat after each turn.
•
CAUTION
The 32° cutter removes material very quickly.
Check the seat outside diameter frequently to prevent overgrinding.
○After making the 32° grind, return to the seat O.D. mea-
•
surement step above.
To measure the seat width, use a vernier caliper to measure the width of the 45° angle portion of the seat at several places around the seat.
If the seat width is too narrow, repeat the 45° grind until
the seat is slightly too wide, and then return to the seat
O.D. measurement step above.

If the seat width is too wide, make the 60° [A] grind described below.
If the seat width is within the specified range, lap the valve

the specified range.
○To make the 60° grind, fit 60° cutter into the holder, and
slide it into the valve guide.
○Turn the holder, while pressing down lightly.
○After making the 60° grind, return to the seat width measurement step above.

Engine Oil and Oil Filter
WARNING
Motorcycle operation with insufficient, deteriorated, or contaminated engine oil will cause
accelerated wear and may result in engine or transmission seizure, accident, and injury.
Oil Level Inspection
that the engine oil level is between the upper [A]
• Check
and lower [B] levels in the gauge.
NOTE
○Situate the motorcycle so that it is perpendicular to the
ground.
○If the motorcycle has just been used, wait several minutes for all the oil to drain down.
○If the oil has just been changed, start the engine and
run it for several minutes at idle speed. This fills the oil
filter with oil. Stop the engine, then wait several minutes
until the oil settles.
CAUTION
Racing the engine before the oil reaches every part
can cause engine seizure.
If the engine oil gets extremely low or if the oil pump
or oil passages clog up or otherwise do not function
properly, the warning indicator light and oil pressure warning symbol will blink. If this blink stays on
when the engine is running above idle speed, stop
the engine immediately and find the cause.
If the oil level is too high, remove the excess oil, using a
syring or some other suitable device.
If the oil level is too low, add the correct amount of oil
through the oil filler opening. Use the same type and
make of oil that is already in the engine.
NOTE
○If the engine oil type and make are unknown, use any
brand of the specified oil to top off the level in preference
to running the engine with the oil level low. Then at your
earliest convenience, change the oil completely.

The connecting rod big end is bolted using the “plastic
region fastening method”.
○This method precisely achieves the needed clamping
force without exceeding it unnecessarily, allowing the
use of thinner, lighter bolts further decreasing connecting
rod weight.
○There are two types of the plastic region fastening. One is
a bolt length measurement method and other is a rotation
angle method. Observe one of the following two, but the
bolt length measurement method is preferable because
this is a more reliable way to tighten the big end nuts.
CAUTION
The connecting rod bolts are designed to stretch
when tightened. Never reuse the connecting rod
bolts. See the table below for correct bolt and nut
usage.
CAUTION
Be careful not to overtighten the nuts.
The bolts must be positioned on the seating surface
correctly to prevent the bolt heads from hitting the
crankcase.
(1) Bolt Length Measurement Method
Be sure to clean the bolts, nuts, and connecting rods
thoroughly with a high-flash point solvent, because the
new connecting rods, bolts, and nuts are treated with an
anti-rust solution.
•
WARNING
Clean the bolts, nuts, and connecting rods in a well
-ventilated area, and take care that there is no spark
or flame anywhere near the working area. This includes any appliance with a pilot light. Because of
the danger of highly flammable liquids, do not use
gasoline or low-flash point solvents to clean them.
CAUTION
Immediately dry the bolts and nuts with compressed air after cleaning.
Clean and dry the bolts and nuts completely.

(2) Rotation Angle Method
If you do not have a point micrometer, you may tighten
the nuts using the “Rotation Angle Method”.
Be sure to clean the bolts, nuts and connecting rods thoroughly with a high-flash point solvent, because the new
connecting rods, bolts and nuts are treated with an anti

Tire Repair
Currently two types of repair for tubeless tires have come
into wide use. One type is called a temporary (external) repair which can be carried out without removing the tire from
the rim, and the other type is called permanent (internal)
repair which requires tire removal. It is generally understood that higher running durability is obtained by permanent (internal) repairs than by temporary (external) ones.
Also, permanent (internal) repairs have the advantage of
permitting a thorough examination for secondary damage
not visible from external inspection of the tire. For these
reasons, Kawasaki does not recommend temporary (external) repair. Only appropriate permanent (internal) repairs
are recommended. Repair methods may vary slightly from
make to make. Follow the repair methods indicated by the
manufacturer of the repair tools and materials so that safe
results can be obtained.

Caliper Fluid Seal Damage
The fluid seal (piston seal) [A] is placed around the piston to maintain clearance between the pad and the disc. If
the seal is in a poor condition, it could lead the pad to wear
excessively or the brake to drag, which may cause the temperature of the discs or the brake fluid to increase.
Replace the fluid seal if it exhibits any of the conditions
listed below.
○Brake fluid leakage around the pad.
○Brakes overheat.
○Considerable difference in inner and outer pad wear.
○Seal and piston are stuck together.
If the fluid seal is replaced, replace the dust seal [B] as
well. Also, replace all seals every other time the pads are
changed.

Rear Caliper Holder Shaft Wear
The caliper body must slide smoothly on the caliper holder
shafts [A]. If the body does not slide smoothly, one pad will
wear more than the other, pad wear will increase, and constant drag on the disc will raise brake and brake fluid temperature.
Check to see that the caliper holder shafts are not badly
worn or stepped, and that the rubber friction boots are not
damaged.
If the rubber friction boot is damaged, replace the rubber
friction boot. To replace the friction boot, remove the pads
and the caliper bracket.
If the caliper holder shaft is damage, replace the caliper

Brake Line Bleeding
The brake fluid has a very low compression coefficient so
that almost all the movement of the brake lever or pedal
is transmitted directly to the caliper for braking action. Air,
however, is easily compressed. When air enters the brake
lines, brake lever or pedal movement will be partially used
in compressing the air. This will make the lever or pedal feel
spongy, and there will be a loss in braking power.
WARNING
Be sure to bleed the air from the brake line whenever brake lever or pedal action feels soft or
spongy after the brake fluid is changed, or whenever a brake line fitting has been loosened for any
reason.
NOTE
○The procedure to bleed the front brake line is as follows.

brake.

WARNING
When working with the disc brake, observe the precautions listed below.
1. Never reuse old brake fluid.
2. Do not use fluid from a container that has been left
unsealed or that has been open for a long time.
3. Do not mix two types and brands of fluid for use in
the brake. This lowers the brake fluid boiling point
and could cause the brake to be ineffective. It may
also cause the rubber brake parts to deteriorate.
4. Don’t leave the reservoir cap off for any length of
time to avoid moisture contamination of the fluid.
5. Don’t change the fluid in the rain or when a strong
wind is blowing.
6. Except for the disc pads and disc, use only disc
brake fluid, isopropyl alcohol, or ethyl alcohol for
cleaning of the brake parts. Do not use any other
fluid for cleaning these parts. Gasoline, engine oil,
or any other petroleum distillate will cause deterioration of the rubber parts. Oil spilled on any part will
be difficult to wash off completely and will eventually
deteriorate the rubber used in the disc brake.
7. When handling the disc pads or disc, be careful that
no disc brake fluid or any oil gets on them. Clean off
any fluid or oil that inadvertently gets on the pads or
disc with a high-flash point solvent. Do not use one
which will leave an oily residue. Replace the pads
with new ones if they cannot be cleaned satisfactorily.
8. Brake fluid quickly ruins painted surfaces; any
spilled fluid should be completely wiped up immediately.
9. If any of the brake line fittings or the bleed valve is
opened at any time, the AIR MUST BE BLED FROM
THE BRAKE LINE.

Precautions
There are a number of important precautions that are
musts when servicing electrical systems. Learn and observe all the rules below.
○Do not reverse the battery cable connections. This will
burn out the diodes on the electrical parts.
○Always check battery condition before condemning other
parts of an electrical system. A fully charged battery is a
must for conducting accurate electrical system tests.
○The electrical parts should never be struck sharply, as
with a hammer, or allowed to fall on a hard surface. Such
a shock to the parts can damage them.
○To prevent damage to electrical parts, do not disconnect
the battery cables or any other electrical connections
when the ignition switch is on, or while the engine is
running.
○Because of the large amount of current, never keep the
starter button pushed when the starter motor will not turn
over, or the current may burn out the starter motor windings.
○Take care not to short the cables that are directly connected to the battery positive (+) terminal to the chassis
ground.
○Troubles may involve one or in some cases all items.
Never replace a defective part without determining what
CAUSED the failure. If the failure was caused by some
other item or items, they must be repaired or replaced, or
the new replacement will soon fail again.
○Make sure all connectors in the circuit are clean and tight,
and examine leads for signs of burning, fraying, etc. Poor
leads and bad connections will affect electrical system
operation.
○Measure coil and winding resistance when the part is cold
(at room temperature).

If any wiring is poor, replace the damaged wiring.
Pull each connector [A] apart and inspect it for corrosion,
dirt, and damage.
If the connector is corroded or dirty, clean it carefully. If it
is damaged, replace it.
Check the wiring for continuity.
○Use the wiring diagram to find the ends of the lead which
is suspected of being a problem.
○Connect the hand tester between the ends of the leads.

or connected, sparks can arise at electrical connections, causing damage to electrical and DFI parts.
Battery Activation
Electrolyte Filling
Make sure that the model name [A] of the electrolyte container matches the model name [B] of the battery. These
names must be the same.
•
Battery Model Name for ZX1000E: YT12B-BS
CAUTION
Be sure to use the electrolyte container with the
same model name as the battery since the electrolyte volume and specific gravity vary with the
battery type. This is to prevent overfilling of the
electrolyte, shorting the battery life, and deterioration of the battery performance.

proper operation.
CAUTION
Removal of the container before it is completely
empty can shorten the service life of the battery. Do
not remove the electrolyte container until it is completely empty and 20 minutes have elapsed.

battery, never remove the caps, nor add water or
electrolyte to the battery.
ELECTRICAL SYSTEM 16-25
Battery
NOTE
○To ensure maximum battery life and customer satisfac-
tion, it is recommended the battery be load tested at
three times its amp-hour rating for 15 seconds.
Re-check voltage and if less than 12.8 volts repeat the
charging cycle and load test. If still below 12.8 volts the
battery is defective.
Precautions
1) No need of topping-up
No topping-up is necessary in this battery until it ends its life under normal use. Forcibly prying off the
seal cap to add water is very dangerous. Never do that.
2) Refreshing charge
If an engine will not start, a horn sounds weak, or lamps are dim, it indicates the battery has been
discharged. Give refresh charge for 5 to 10 hours with charge current shown in the specification
(see this chapter).
When a fast charge is inevitably required, do it following precisely the maximum charge current
and time conditions indicated on the battery.
CAUTION
This battery is designed to sustain no unusual deterioration if refresh-charged according
to the method specified above. However, the battery’s performance may be reduced noticeably if charged under conditions other than given above. Never remove the seal cap
during refresh charge.
If by chance an excessive amount of gas is generated due to overcharging, the relief valve
releases the gas to keep the battery normal.
3) When you do not use the motorcycle for months:
Give a refresh charge before you store the motorcycle and store it with the negative cable removed. Give a refresh charge once a month during storage.
4) Battery life:
If the battery will not start the engine even after several refresh charges, the battery has exceeded its useful life. Replace it (Provided, however, the vehicle’s starting system has no problem).
WARNING
Keep the battery away from sparks and open flames during charging, since the battery
gives off an explosive gas mixture of hydrogen and oxygen. When using a battery charger,
connect the battery to the charger before turning on the charger.
This procedure prevents sparks at the battery terminals which could ignite any battery
gases.
No fire should be drawn near the battery, or no terminals should have the tightening loosened.
The electrolyte contains sulfuric acid. Be careful not to have it touch your skin or eyes. If
touched, wash it off with liberal amount of water. Get medial attention if severe.
Interchange
A sealed battery can fully display its performance only when combined with a proper vehicle electric
system. Therefore, replace a sealed battery only on a motorcycle which was originally equipped with
a sealed battery.
Be careful, if a sealed battery is installed on a motorcycle which had an ordinary battery as original
equipment, the sealed battery’s life will be shortened.

Alternator Inspection
There are three types of alternator failures: short, open
(wire burned out), or loss in rotor magnetism. A short or
open in one of the coil wires will result in either a low output,
or no output at all. A loss in rotor magnetism, which may be
caused by dropping or hitting the alternator, by leaving it
near an electromagnetic field, or just by aging, will result in
low output.

If there is more resistance than shown in the table, or
no tester reading (infinity) for any two leads, the stator
has an open lead and must be replaced. Much less than
this resistance means the stator is shorted, and must be
replaced.
Using the highest resistance range of the hand tester,
measure the resistance between each of the white leads
and chassis ground.
Any hand tester reading less than infinity (∞) indicates a
short, necessitating stator replacement.
If the stator coil has normal resistance, but the voltage
check showed the alternator to be defective; then the rotor
magnets have probably weakened, and the rotor must be
replaced.

ELECTRICAL SYSTEM 16-79
Immobilizer System (Equipped Models)
This motorcycle is equipped with an immobilizer system to protect the motorcycle from theft. This
system provides a theft proof device by means of matching a code between the inbuilt key transponder and ECU. If the code does not match, ignition system, injectors, sub-throttle valve actuator and
exhaust butterfly valve actuator will not operate and the engine will not start.
Abstract
Do not keep more than one immobilizer key of any system on a key ring. Jamming of the key code
signal may occur and the operation of the system may be affected.
The warning indicator light (LED) will flash for a period of 24 hours once the ignition switch has been
switched off and the key removed. This flashing can be set to on or off as desired by holding the
MODE and RESET buttons down for 2 seconds within 20 seconds of switching the ignition off.
If all coded keys (master key and user keys) are lost the ECU and ignition switch will have to be
replaced.
The immobilizer system can not function until the master key code is registered in the ECU.
A total of six keys can be registered in the ECU at any one time (one master key and five user keys).
If the master key is lost it is not possible to register new user keys.

Your Motorcycle has been designed and manufactured to provide you optimum safety and convenience. However, in order to fully benefit from Kawasaki’s safety engineering and craftsmanship, it is essential that you, the owner and operator, properly maintain your motorcycle and become thoroughly familiar with its operation. Improper maintenance can create a dangerous situation known as throttle failure. Two of the most common causes of throttle failure are:

1. An improperly serviced or clogged air cleaner may allow dirt and dust to enter the throttle body and stick the throttle open. 2. During removal of the air cleaner, dirt is allowed to enter and jam the fuel injection system. In an emergency situation such as throttle failure, your vehicle may be stopped by applying the brakes and disengaging the clutch. Once this stopping procedure is initiated, the engine stop switch may be used to stop the engine.

If the engine stop switch is used, turn off the ignition switch after stopping the motorcycle.
