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

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 them remove them. 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, 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 new gaskets and replace 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.

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.

Apply specified grease to the lip of seal before installing the seal.

Circlips, Cotter Pins

Replace circlips or cotter pins that were removed with new ones. 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.

1-6 GENERAL INFORMATION

Before Servicing

Direction of Engine Rotation

When rotating the crankshaft by hand, the free play amount of rotating direction will affect the adjustment. 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.

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.

2-18 PERIODIC MAINTENANCE

Periodic Maintenance Procedures

Coolant Level Inspection

NOTE

○Check the level when the engine is cold (room or ambient temperature).

•Lean the motorcycle slightly to the left 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].

NOTE

○Remove the radiator cap in two steps. First turn the cap counterclockwise to the first stop and wait there for a few seconds. Then push down and turn it further in the same direction and remove the cap.

•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:

1.05 L (1.11 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.

PERIODIC MAINTENANCE 2-19

Periodic Maintenance Procedures

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.

Torque — Radiator Hose Clamp Screws: 1.5 N·m (0.15 kgf·m, 13 in·lb)

○Valve clearance must be checked and adjusted when the engine is cold (at room temperature).

•Remove:Cylinder Head Cover (see Cylinder Head Cover Removal in the Engine Top End chapter)

Balancer Shaft Cap [A] Timing Inspection Cap [B]

Special Tool — Filler Cap Driver: 57001-1454

•First, bring the piston to the top-dead-center of its compression stroke to inspect the valve clearance (the position at the end of the compression stroke), when the cam lobe faces outside of the camshaft.

○Place a wrench over the balancer weight nut and turn it counterclockwise to align the TDC mark [A] with the center of the groove [B] of the inspection hole.

Don’t use the shims for another models. This could cause wear of the valve stem end, and valve stem damage.

PERIODIC MAINTENANCE 2-21

Periodic Maintenance Procedures

Adjustment shims

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 [A] toward the valve lifter [B]. 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.

•Applylifter. engine oil to the valve lifter surface and install the

•Install the camshaft (see Camshaft Installation in the Engine Top End chapter).

2-22 PERIODIC MAINTENANCE

Periodic Maintenance Procedures

Cylinder Head Warp Inspection

•Remove the cylinder head (see Cylinder Head Removal in the Engine Top End chapter).

•Lay a straightedge [A] across the lower surface of the head at several different points, and measure warp by inserting a thickness gauge between the straightedge and

the head.

If warp exceeds the service limit, repair the mating surface. Replace the cylinder head if the mating surface is badly damaged.

Cylinder Head Warp

Service Limit: 0.05 mm (0.002 in.)

•Remove the valves (see Valve Removal in the Engine Top End chapter).

•Scrape the carbon out of the combustion chamber and exhaust port with a scraper [A] or a suitable tool.

•Clean the cylinder head, using high-flash point solvent.

•Blow out any particles which may obstruct the oil passage in the cylinder head using compressed air.

•Install the valves (see Valve Installation in the Engine Top End chapter).

Cylinder Wear Inspection

NOTE

○Measure the cylinder inside diameter when the cylinder is cold (room or ambient temperature).

•Visually Inspect the inside of the cylinder for scratches and abnormal wear.

If the cylinder is damaged or badly worn, replace it with a new one.

•Since there is a difference in cylinder wear in different directions, take a side-to-side and a front-to back measurement shown in the figure.

If any of the cylinder inside diameter measurements exceeds the service limit, the cylinder must be replaced with a new one since the PLATING cylinder cannot be bored or honed.

[A]10 mm (0.39 in.)

[B]30 mm (1.2 in.)

[C]50 mm (2.0 in.)

Cylinder Inside Diameter

Standard: 96.000 96.012 mm (3.7795 3.7800 in.), and less than 0.01 mm (0.0004 in.) difference between any two measurements.

Service Limit: 96.10 mm (3.783 in.), or more than 0.05 mm (0.020 in.) difference between any two measurements.

PERIODIC MAINTENANCE 2-23

Periodic Maintenance Procedures

Piston/Cylinder Clearance

The piston-to-cylinder clearance is measured whenever a piston or cylinder is replaced with a new one. The standard piston-to-cylinder clearance must be adhered to whenever the cylinder is replaced.

If only a piston is replaced, the clearance may exceed the standard slightly. But it must not be less than the minimum, in order to avoid piston seizure.

The most accurate way to find the piston clearance is by making separate piston and cylinder diameter measurements and then computing the difference between the two values. Measure the piston diameter as just described, and measure the cylinder diameter at the very bottom of the cylinder.

Piston/Cylinder Clearance

Standard: 0.020 0.042 mm (0.00079 0.0016 in.)

Piston, Piston Ring and Piston Pin Replacement

•Refer to the Cylinder and Piston Section in Engine Top End chapter.

Exhaust System Inspection

•The exhaust system, in particular the silencer, is designed to reduce exhaust noise and conduct the exhaust gases away from the rider while minimizing power loss. If carbon has built up inside the silencer, exhaust efficiency is

reduced, causing engine performance to drop.

If the silencer is badly damaged, dented, cracked or rusted, replace it. Replace the silencer packing if the exhaust noise becomes too loud or engine performance drops.

Muffler Baffle Change

•Remove the muffler (see Muffler Removal in the Engine Top End chapter).

•Remove the muffler pipe bolts [A].

•Tap the bracket [A] of the muffler body with a plastic mallet [B] to separate from the inner pipe.

If it does not, adjust the lever play.

Clutch Lever Free Play Adjustment

•Slide the clutch lever dust cover out of place.

•Turn the adjuster [A] so that the clutch lever will have 8 13 mm (0.3 0.5 in.) of play.

NOTE

○Be sure that the outer cable end at the clutch lever is fully seated in the adjusting bolt at the clutch lever, or it could slip into the place later, creating enough cable play to prevent clutch disengagement.

•If it cannot be done, loosen the locknut [A] at the middle of the clutch cable, and turn the adjusting nut [B] so that clutch lever has 8 13 mm (0.3 0.5 in.) of play.

•After the adjustment is made, tighten the locknut, and start the engine and check that the clutch does not slip and that it release properly.

Friction and Steel Plates Inspection

•Remove the clutch plates (see Clutch Removal in the Engine Right Side chapter).

•Visually inspect the friction and steel plates to see if they show any signs of seizure, or uneven wear.

If any plates show signs of damage, replace the friction plates and steel plates as a set.

•Measurecalipers. the thickness [A] of the friction plates with vernier If they have worn past the service limit, replace them with new ones.

Friction Plate Thickness

Standard: 2.92 3.08 mm (0.115 0.121 in.)

Service Limit: 2.6 mm (0.10 in.)

2-26 PERIODIC MAINTENANCE

Periodic Maintenance Procedures

•Place each friction plate or steel plate on a surface plate, and measure the gap between the surface plate [A] and each friction plate or steel plate [B] with a thickness gauge

[C]. The gap is the amount of friction or steel plate warp. If any plate is warped over the service limit, replace it with

a new one.
