F. Steering Head Adjustment
The steering assembly should be checked periodically for looseness.
1. Raise the front end of the motorcycle so that there is no weight on the front wheel.
2. Grasp the bottom of the forks and gently rock the fork assembly backward and forward, checking for looseness in the steering assembly bearings.
3. If there is looseness in the steering head, loosen the steering stem and front fork pinch bolts and steering fitting bolt.
4. Use a steering nut wrench to loosen top steering fitting nut. The top nut serves as a lock nut.
5. Tighten the lower steering fitting nut until the steering head is tight, but does not bind when forks are turned.
6. Retighten the top steering fitting nut, steering fitting bolt and steering stem and front fork pinch bolts, in that order.
7. Recheck steering adjustment to make sure there is no binding when the forks are moved from lock to lock. If necessary, repeat adjustment procedure.
G. Cable Inspection and Lubrication
—WARNING:--
Damage to the outer housing of the various cables, may cause corrosion and often free movement will be obstructed. An unsafe condition may result so replace such cables as soon as possible.
1. If the inner cables do not operate smoothly, lubricate or replace them.
Recommended lubricant:
Yamaha Chain and Cable Lube or SAE 10W/30 motor oil
H. Throttle Cable and Grip Lubrication
The throttle twist grip assembly should be greased when the cable is lubricated, since the grip must be removed to get at the end of the throttle cable. Two screws clamp the throttle housing to the handlebar. Once these two are removed, the end of the cable can be held high to pour in several drops of lubricant. With the throttle grip disassembled, coat the metal surface of the grip assembly with a suitable all-purpose grease to cut down friction.
I. Rear Arm Pivot Bearings
The swing arm must pivot freely on its bearings but not have any excess play. Check and adjust pivot bearings if necessary. (Refer to CHAPTER 5. SWING ARM).
J. Brake and Change Pedals/Brake and Clutch Levers
Lubricate the pivoting parts of each lever and pedal.
Recommended lubricant: Yamaha Chain and Cable Lube or SAE 10W/30 motor oil
K.Center and Side Stand Pivots
Lubricate the center and side stands at their pivot points.
Recommended lubricants: Yamaha Chain and Cable Lube or SAE 10W/30 motor oil
