EAU01106Drive chain lubrication
The chain consists of many parts
which work with each other. If the
chain is not maintained properly, it
will wear out quickly. Therefore,
the chain must be serviced regular-
ly. This service is especially neces-
sary when riding in dusty areas.
1. The drive chain should be
lubricated every 500 km. First,
remove all dirt and mud from
the chain with a brush or cloth.
Then, spray any of the many
brands of spray-type chain
lubricant between both rows
of side plates and on all center
rollers.
2. To clean the chain thoroughly,
remove it from the motorcycle,
dip it in solvent, and clean out
as much dirt as possible. Then,
take the chain out of the sol-
vent to dry it, and immediately
lubricate it to prevent it from
rusting.

Cable inspection and
lubrication
EW000112
w
Damage to the outer housing of
cables may lead to internal rusting
and interfere with the cable move-
ment. Replace damaged cables as
soon as possible to prevent unsafe
conditions.
Lubricate the cables and cable
ends. If a cable does not operate
smoothly, ask a Yamaha dealer to
replace it.
Recommended lubricant:
Same as engine oil
EAU00773
Throttle cable and grip
lubrication
The throttle twist grip assembly
should be greased at the time that
the cable is lubricated, since the
grip must be removed to get at the
end of the throttle cable. After
removing the screws, hold the end
of the cable up in the air and put in
several drops of lubricant. With the
throttle grip disassembled, coat the
metal surface of the grip assembly
with a suitable all-purpose grease.
EAU00776
Brake and shift pedal
lubrication

EAU00793Front fork inspection
EW000115
w
Securely support the motorcycle
so there is no danger of it falling
over.
1. Visual check
Check for scratches or damage
on the inner tube and exces-
sive oil leakage from the front
fork.2. Operation check
Place the motorcycle on a level
place.
a. Hold the motorcycle in an
upright position and apply the
front brake.
b. Push down hard on the han-
dlebars several times and
check if the fork rebounds
smoothly.
EC000098
cC
If any damage or unsmooth move-
ment is found with the front fork,
consult a Yamaha dealer.
EAU00794Steering inspection
Periodically inspect the condition
of the steering. Worn out or loose
steering bearings may be danger-
ous. Place a stand under the
engine to raise the front wheel off
the ground. Hold the lower end of
the front forks and try to move
them forward and backward. If any
free play can be felt, ask a Yamaha
dealer to inspect and adjust the
steering. Inspection is easier if the
front wheel is removed.
