9Owners are personally responsible for their vehicleÕs condition. Your motorcycleÕs vital functions can start to deteriorate
quickly and unexpectedly, even if it remains unused (for instance, if it is exposed to the elements). Any damage, fluid
leak or loss of tire pressure could have serious consequences. Therefore, it is very important that, in addition to a thor-
ough visual inspection, you check the following points before each ride.

up, check for oil leakage. If oil
leakage is found, stop the engine
immediately and check for the
cause.

Start the engine and keep it
idling until oil flows out of the
bleed hole. If no oil comes out
after one minute, turn off the
engine immediately so it will
not seize. In such a case go to
the nearest Yamaha dealer for
repairs.

After checking, tighten the air
bleed screw securely.

Drive chain lubricationThe 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 regularly.
This service is especially necessary
when riding in dusty areas. This
motorcycle is equipped with a sealed
type chain. Steam cleaning, high-
pressure washers, and solvents can
damage the drive chain, so do not
use these for cleaning it. Use only
kerosene to clean the drive chain.
Wipe it dry, and thoroughly lubricate it
with SAE 30 ~ 50W motor oil. Do not
use any other lubricants on the drive
chain. They may contain solvents
that could damage the sealed chain. Tightening torque:
Axle nut:
105 Nm (10.5 m
0kg)
Caliper bracket bolt:
48 Nm (4.8 m
0kg)

2.Turn both left and right chain
adjusting plates the same

in the same position for proper
wheel alignment. To tighten the
