CABLE INSPECTION AND LUBRICATION

Cable inspection and lubrication steps:
•   Remove the two screws that secure throttle housing to handlebar.
•   Hold cable end high and apply several drops of lubricant to cable.
•   Coat metal surface of disassembled throttle twist grip with suitable all-purpose grease to minimize friction.

REAR SHOCK ABSORBER ADJUSTMENT

If the spring seat is raised, the spring becomes stiffer, and if lowered, it becomes softer.

Standard Position: B      A. — Softest (1) E. — Stiffest (2)

Always adjust each shock absorber to the same setting. Uneven adjustment can cause poor handling and loss of stability.

The tapered side of ring nuts must face downward.

• Loosen the ring nut (7) completely and retighten it to specification.

Ring Nut (Lower):
6Nm(0.6 m-kg,4.3ft-lb)

•   Check the steering stem by turning it lock to lock. If there is any binding, remove the steering stem assembly and inspect the steering bearings 8 .

(See CHAPTER 5, STEERING HEAD for more details.)

•   Hand-tighten the ring nut (6) , then align the slots of both ring nuts. If not aligned, hold the lower ring nut (7) and tighten the other until they are aligned.

•   Install the lock washer (5) .

WHEEL BEARINGS 

 

Front Wheel Bearings

1. Raise the front end of the motorcycle, and spin the wheel by hand. Touch the axle or front fork while spinning the wheel-Excessive vibration — Replace bearings.

Rear Wheel Bearings

1.      Remove: 
•   Rear wheel

2.      Check:
•   Bearing movement Rotate with the fingers. Roughness/Wear — Replace.

 

 

TUBELESS TIRES AND ALUMINUM WHEELS

•   Always inspect aluminum wheels before a ride.
•   Place the motorcycle on its centerstand and check for cracks, bends, or warpage of the wheels.
•   Do not attempt any repairs to the wheel; replace any defective wheel.
•   Do not attempt to use tubeless tires on a wheel designed for use with tube-type tire only. Tire failure and subsequent personal injury may result from sudden deflation.
•   Be sure to install the proper tube when using tube-type tires.
•   New tires have a relatively poor adhesion on the road surface so do not allow them to be subjected to high speed load from maximum speed until after a break-in run of approx. 100 km (60 mi).
•   Always use the correct tire inflation pressure acording to the operating conditions.

NOTE:
Always balance the wheel when a tire or wheel has been changed or replace.

Ride conservatively after installing a tire to allow it to seat itself properly on the rim.
