GENERAL INFORMATION 1-1

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:

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.

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.

GENERAL INFORMATION 1-3

Before Servicing

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.

Tightening Sequence

Bolts, nuts, or screws must be tightened according to the specified sequence to prevent case warpage or deformation which can lead to malfunction. If the specified tightening sequence is not indicated, tighten the fasteners alternating diagonally.

1-4 GENERAL INFORMATION

Before Servicing

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 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, Oring

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 new gaskets and replace used O-rings 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 before applying liquid gasket or locking agent. Do not apply them excessively. Excessive application can clog oil passages and cause serious damage.

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.

GENERAL INFORMATION 1-5

Before Servicing

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 that 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. 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).

1-6 GENERAL INFORMATION

Before Servicing

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.

Periodic Maintenance Procedures

Fuel System

Fuel Hose and Connection Inspection

○The fuel hoses are designed to be used throughout the motorcycle’s life without any maintenance, however, if the motorcycle is not properly handled, the inside the fuel line

•can cause fuel to leak [A] or the hose to burst. Check the fuel hose.

Replace the fuel hose if any fraying, cracks [B] or bulges [C] are noticed.

•Check that the hose [A] are securely connected and

•clamps [B] are tightened correctly.

When installing, route the hose according to Cable, Wire,

•and Hose Routing section in the Appendix chapter. When installing the fuel hose, avoid sharp bending, kinking, flattening or twisting, and route the fuel hose with a minimum of bending so that the fuel flow will not be obstructed.

Replace the hose if it has been sharply bent or kinked.

Throttle• Grip Free Play Inspection

Check throttle grip free play [B] by lightly turning the throttle grip [A] back and forth.

If the free play is improper, adjust the throttle cable.

•Check that the throttle grip moves smoothly from full open to close, and the throttle closes quickly and completely in all steering positions by the return spring.

If the throttle grip does not return properly, check the throttle cable routing, grip free play, and cable damage. Then

•lubricate the throttle cable.

Run the engine at the idle speed, and turn the handlebar all the way to the right and left to ensure that the idle speed does not change.

If the idle speed increase, check the throttle cable free play and the cable routing.

•Start the engine and warm it up thoroughly.

•Turn the idle adjusting screw [B] until the idle speed is correct.

To increase idle speed [C]

• To decrease idle speed [D]

Open and close the throttle a few times to make sure that the idle speed is with in the specified range. Readjust if necessary.

Air Cleaner Element Cleaning and Inspection

NOTE

○In dusty areas, the element should be cleaned more frequently than recommended interval.

○After riding through rain or on muddy roads, the element should be cleaned immediately.

○Since repeated cleaning opens the pores of the element, replace it with a new one in accordance with the Periodic Maintenance Chart. Also, if there is a break in the element material or any other damage to the element, replace the element with a new one.

WARNING

Clean the element in a well-ventilated area, and take care that there are no sparks 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 a low flash-point solvent to clean the element.

2-14 PERIODIC MAINTENANCE

Periodic Maintenance Procedures

•Remove:

•Tighten the wing bolt [D] Install the seat.

Cooling System

WARNING

To avoid burns, do not remove the radiator cap or try to change the coolant when the engine is still hot. Wait until it cools down.

Coolant on tires will make them slippery and can cause an accident and injury. Immediately wash away any coolant that spills on the wheels.

Since coolant is harmful to the human body, do not use for drinking.

Coolant Level Inspection

NOTE

○Check the level when the engine is cold (room or ambi-

•Lean the motorcycle slightly to the right until the radiator cap is level to the ground so that the radiator cap is located uppermost in order to exhaust the air accumulated in the

•radiator.

Remove the radiator cap [A].ent temperature).

2-16 PERIODIC MAINTENANCE

Periodic Maintenance Procedures

•Check the coolant level. The coolant level [A] should be at the bottom of the filler neck [B].

If the coolant level is low, add coolant through the filler opening to the bottom of the filler neck. Install the cap.

Recommended coolant:

Permanent type of antifreeze (soft water and ethylene glycol plus corrosion and rust inhibitor chemicals for aluminum engines and radiators)

Water and coolant mixture ratio: 1:1 (water 50 %, Coolant 50 %)

Total amount:

1.2 L (1.27 US qt.)

Coolant• Deterioration Inspection

Visually inspect the coolant.

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.

Radiator Hoses and Connections Inspection

○The high pressure inside the radiator hose [A] can cause coolant to leak [B] or the hose to burst if the line is not properly maintained. Visually inspect the hoses for signs of deterioration. Squeeze the hoses. A hose should not be hard and brittle, nor should it be soft or swollen.

Replace the hose if any fraying, cracks [C] or bulges [D]

•are noticed.

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