Observe these precautions:
8When checking the fluid level, make
sure that the top of the master cylin-
der is level by turning the handlebars.
8Use only the recommended quality
brake fluid, otherwise the rubber seals
may deteriorate, causing leakage and
poor braking 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 braking performance.8Be careful that water does not enter
the master cylinder when refilling.
Water will significantly lower the boil-
ing point of the fluid and may result in
vapor lock.
8Brake fluid may deteriorate painted
surfaces or plastic parts. Always clean
up spilled fluid immediately.
8As the brake pads wear, it is normal
for the brake fluid level to gradually
go down. However, if the brake fluid
level goes down suddenly, have a
Yamaha dealer check the cause. Recommended brake fluid: DOT 4

Drive chain slack adjustment
1. Loosen the rear brake adjuster.
2. Loosen the axle nut.
3. Loosen the sprocket shaft nut and the
axle nut.
4. To tighten the chain, turn the chain ad-
juster clockwise. To loosen the chain,
turn the adjuster counterclockwise and
push the wheel forward. Turn each ad-
juster exactly the same amount to main-
tain correct axle alignment. There are
marks on each side of the swingarm and
a match mark on each chain puller. Use
these marks to align the rear wheel.

Too little chain slack will overload the en-
gine and other vital parts. Keep the slack
within the specified limits.

3. Remove the drive chain. Thoroughly
clean the chain with solvent and lubri-
cate it. Reinstall the chain or store it in
a plastic bag (tied to frame for safe-
keeping).
4. Lubricate all control cables.
5. Block up the frame to raise both
wheels off the ground.
6. Tie a plastic bag over the exhaust pipe
outlet to prevent moisture from enter-
ing.
7. If storing in a humid or salt-air atmos-
phere, coat all exposed metal surfaces
with a light film of oil. Do not apply oil
to any rubber parts or the seat cover.
8. Remove the battery and charge it.
Store it in a dry place and recharge it
once a month. Do not store the bat-
tery in an excessively warm or cold
place (less than 0°C (32°F) or more
than 30°C (86°)).
