SERVICE INFORMATION

GENERAL

Never ride on the rim.
When using a lock nut wrench, use a 20 inch long deflection bea type torque wrench. The lock nut wrench increases the torque wrenche's leverage, so the torque wrench reading will be less than the torque actually applied tothe lock nut.

WARNING

A contaminated brake disk or pad reduces stopping power. Discard contaminated pads and clean a contaminated disk with a high quality brake degreasing agent.
Inhaled asbestos fibers have been found to cause respiratory disease and cancer. Never use adn air hose or dry brush to clean brake assemblies. Use an OSHA-approved vacuum cleaner or alternate method abroved OSHA designed to minimize the hazard caused by airborne asbestos fibers.
The shock absorber contains nitrogen gas under high pressure. Do not allow fire or heat near the shock abosrber.
Before disposal of the shock absorber, release the nitrogen. (see page 13-16)

REAR WHEEL

REMOVAL

WARNING

Do not service the rear wheel (removal/installation) while exhaust system is hot.

CAUTION

Cover the left rim edge, spindle edge and brake caliper with tape to avoid damaging the wheel.

NOTE

The sprocket and driven flange dampers can be removed without removing the wheel (see page 13-6).

Place the motorcycle on its center stand.
Remove the center cap and cotter pin. Loosen the wheel nut, but do not remove it.

Loosen the eccentric bearing carrier pinch bolt and turn the carrier counterclockwise until it stops to obtain maximum chain slack.
Remove the chain from the rear sprocket and place it on the outside of the sprocket.
Rotate the eccentric bearing carrier to its rearward most (maximum chain slack) position.

Remove the wheel nut, shim and axle center collar.

Tap the axle with soft hammer and push the axle in until it clears the wheel.

Attach tape to the wheel rim, edge of the spindle and brake caliper to avoid damaging the wheel.

Remove the wheel from the drive pins, then angle it to the right and pull it backward to go between the brake disc and muffler.

CAUTION

Be careful not to damage the wheel rim and brake disc when removing the wheel.

Then, as the wheel reaches the hub, angle it to the left and pull it out backward as shown.

CAUTION

Be careful not to damage the wheel rim and brake caliper when removing the wheel.

Page 13-4

INSPECTION

Wheel rim runout
Check the rim runout by placing the wheel in a truing stand.
Spin the wheel slowly and read the runout using a dial indicator.

SERVICE LIMITS:
RADIAL RUNOUT: 2.0 mm (0.08 in) AXIAL RUNOUT: 2.0 mm (0.08 in)

NOTE

The wheel cannot be repaired and must be replaced with a new one if the service limits are exceeded.

Wheel Balance CAUTION

Wheel balance directly affects the stability, handling and overall safety of the motorcycle. Always check balance when the tire has been removed from the rim.

NOTE

For optimum balance, the tire balance mark (a paint dot on the side wall) must be located next to the valve stem. Remount the tire if necessary.

Remove the dust seal from the wheel.
Mount the wheel and tire assembly in an inspection stand.
Spin the wheel, allow it to stop, and mark the lowest (heaviest) part of the wheel with chalk.
Do this two or three times to verify the heaviest area. If the wheel is balanced, it will not stop consistently in the same position.

To balance the wheel, install wheel weights on the highest side of the rim, the side opposite the chalk marks. Add just enough weight so the wheel will no longer stop in the same position when it's spun.
Do not add more than 60 grams to the rear wheel.

Drive pin hole
Check the drive pin holes for the damage.

Inspection and replacement of the drive pin: turn to page 13-11.

Page 13-5

INSTALLATION

WARNING

SHOCK ABSORBER

WARNING

The rear shock absorber contains nitrogen under high pressure. Do not allow fire or heat near the shock absorber.
Before disposal of the shock absorber, release the nitrogen.

NOTE

If you plan to disassemble the shock absorber, set the spring adjuster to the softest position at this time.

REMOVAL

Raise the rear wheel off the ground by placing the motorcycle on its center stand.

Remove the seat (page 13-25).
Remove the shock absorber lower mounting bolt while supporting the wheel.

Remove the following:

sub-frame upper mounting bolts

Page 13-15

DISASSEMBLY

Make sure the spring adjuster is set to the softest position before disassembly.

TOOL: Shock absorber compressor attachement 07967-KE10000

Compress the spring until the stop ring can be removed, and remove the stop ring from the shock absorber. Remove the following:

upper spring seat
spring
lower spring seat
spring adjuster
dust seal
lock nut and lower joint
stop rubber
seat

INSPECTION

Inspect the following parts:

damper unit for oil leaks
damper rod for bends or damage
stop rubber for wear or damage

Inspect all the other parts for wear or damage.

Measure the spring free length.

SERVICE LIMIT: 148.3 mm (5.84 in)

Page 13-16

Mark the 10 mm position on the damper rod as shown.
Place the damper rod on a scale and measure the force required to compress the damper to the 10 mm (0.4 in) mark.

COMPRESSION FORCE: 15 - 20 kg (33.1 - 44.1 lb)

If the force required is less than 14.9 kg (32.8 lb), gas is leaking.
Examine the damper rod and replace the damper unit if it is bent or scored.

SHOCK ABSORBER DISPOSAL PROCEDURE

Center punch the damper case to mark the drilling point, approximately 15 mm (0.59 in) from the top surface.
Wrap the damper unit inside a plastic bag.
Support the damper unit upright in a vise as shown.
Through the open end of the bag, insert a drill motor with a sharp 2 - 3 mm (5/64 - 1/8 in) drill bit.

WARNING

Do not use a dull drill bit which could cause a build-up of excessive heat and pressure inside the damper, leading to explosion and severe personal injury.
The shock absorber contains nitrogen gas and oil under high pressure. Do not drill any farther down the damper case than the measurement given above, or you may drill into the oil chamber; oil escaping under high pressure may cause serious personal injury.
Always wear eye protection to avoid getting metal shavings in your eyes when the gas pressure is released.
The plastic bag is only intended to shield you from the escaping gas.

Hold the bag around the drill motor and briefly run the drill motor inside the bag; this will inflate the bag with air from the motor and help keep the bag from getting caught in the bit when you start.

ASSEMBLY

Apply locking agent to the rod threads and install the lock nut.
Screw in the lock nut fully.
Install the seat.
Screw the lower joint onto the damper rod fully, hold it and tighten the lock nut.
