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.

CLEANING AND
STORAGE
EAK01302*A. CLEANING
Frequent, thorough cleaning of your mo-
torcycle will not only enhance its appear-
ance but will improve its general perfor-
mance and extend the useful life of many
components.
1. Rinse the dirt and degreaser off with a
garden hose.EUU34602cCExcessive hose pressure may cause water
seepage and deterioration of wheel bear-
ings, front fork, brakes, transmission seals
and electrical parts.2. After cleaning the motorcycle, dry all
surfaces with a chamois, clean towel,
or soft absorbent cloth.3. Dry the chain and lubricate it to pre-
vent rust.
4. Automotive-type wax may be applied
to all painted and chrome-plated sur-
faces. When finished, start the engine
and let it idle for several minutes.
EAK00700B. STORAGE
Long term storage (60 days or more) of
your motorcycle will require some preven-
tive procedures to guard against deteriora-
tion. After thoroughly cleaning the motor-
cycle, prepare for storage as follows:
1. Drain the fuel tank, fuel lines, and car-
buretor float bowl(s).
2. Remove the empty fuel tank, pour a
cup of SAE 10W30 or 20W40 motor oil
in the tank, shake the tank to coat the
inner surfaces thoroughly and drain
off the excess oil. Reinstall the tank.
