1. If the inner cables do not operate smooth-
ly, lubricate them. If necessary, have your
Yamaha dealer replace them.
Recommended lubricant:
YAMAHA Chain and Cable Spray
Throttle cable and grip lubrication
The throttle twist grip assembly should be
greased at the time that the cable is lubri-
cated, 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 disassem-
bled coat the metal surfaces of the grip
assembly with a suitable all-purpose grease to
cut down friction. (See lubrication chart)
After the installation, check to see that the
throttle grip moves smothly.
Lubrication of levers, pedals, etc.
1. Lubricate the pivoting parts of the brake
and clutch levers with spray lubricant.
2. Lubricate the shaft of the brake pedal
with lithium soap grease.
Steering inspection
Periodically inspect the condition of the
steering. Worn out or loose steering bearings
may be dangerous.
Place a block under the engine to raise the
front wheel of the motorcycle off the ground;
then hold the lower end of the front fork and
try to move forward and backward. If any
freeplay can be felt, as a Yamaha dealer to
inspect and adjust.
Inspection is easier if the front wheel is
removed. Ask a dealer to lubricate the
steering bearings every 6,400 km (4,000 mi.).
More often in case of off road operation.
