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

not seize. In such a case go to
the nearest Yamaha dealer for
repairs.

fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor brake performance.
8Be careful that water does not
enter the master cylinder when
refilling. Water will significantly
lower the boiling point of the fluid
and may result in vapor lock.
8Brake fluid may deteriorate paint-
ed surfaces or plastic parts.
Always clean up spilled fluid
immediately.

Drive chain slack checkNOTE:
Spin the wheel several times and find
the tightest position of the chain.
Check and/or adjust the chain slack
while itÕs in this tightest position.To check the chain slack the motor-
cycle must be held straight up with
both wheels on the ground and with-
out rider. Check the slack at the posi-
tion shown in the illustration. Normal
slack is approximately 30 ~ 40 mm. If
the slack exceeds 40 mm, adjust.

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

Throttle cable and grip
lubricationThe 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 disas-
sembled, coat the metal surface of
the grip assembly with a suitable all-
purpose grease.

If the battery seems to have dis-
charged, consult a Yamaha deal-
er.

If the motorcycle is equipped
with optional electrical acces-
sories, the battery tends to dis-
charge more quickly, so be sure
to recharge it periodically.

Completely recharge the bat-
tery before storing. Storing a
discharged battery can cause
permanent battery damage.

Use a battery charger
designed for a sealed-type
(MF) battery. Using a conven-
tional battery charger will
cause battery damage. If you
do not have a sealed-type bat-
tery charger, contact your
Yamaha dealer.

Always make sure the connec-
tions are correct when rein-
stalling the battery.
