for a few minutes. While
warming up, check for oil leak-
age. If oil leakage is found,
stop the engine immediately
and check for the cause.
10. Stop the engine and check the

98Use only the designated quali-
ty brake fluid. Otherwise, the
rubber seals may deteriorate,
causing leakage and poor
brake performance.
NOTE:
If DOT 4 is not available, DOT 3 can
be used.
8Refill with the same type of
brake 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 significant-
ly lower the boiling point of
the fluid and may result in
vapor lock. Recommended brake fluid:

EAU00732Inspecting the brake fluid
level
Insufficient brake fluid may let air
enter the brake system, possibly
causing the brakes to become inef-

Before riding, check that the brake
fluid is above the minimum level
and fill when necessary.
Observe these precautions:
8When checking the fluid level,
make sure the top of the mas-
ter cylinder is level by turning
the handlebars.

The brake fluid should be replaced
only by trained Yamaha service

EAU00744Drive chain slack check
NOTE:
Spin the wheel several times and
find the tightest position of the
chain. Check and/or adjust the
chain slack while it’s in this tightest
position.
To check the chain slack the motor-
cycle must be held straight up with
both wheels on the ground and
without rider. Check the slack at
the position shown in the illustra-
tion. Normal slack is approximately
30 ~ 40 mm. If the slack exceeds
40 mm, adjust.

EAU00769Drive 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.
This motorcycle is equipped with a
sealed type chain. Steam cleaning,
high-pressure washes, and sol-
vents can damage chain so do not
use these for cleaning it. Use only
kerosene to clean the drive chain.
Wipe it dry, and thoroughly lubri-
cate it with SAE 30 ~ 50W motor
oil. Do not use any other lubricants
on the drive chain. They may con-
tain solvents that could damage
the sealed chain.

EAU00773Throttle 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.

Damage to the outer housing of
cables may lead to internal rusting

If a cable does not operate smooth-
ly, ask a Yamaha dealer to replace it.
