4-PRE-OPERATION CHECKSThe condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or loss
of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual inspec-
tion, to check the following points before each ride.

Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking or clutch per-
formance.


The brake or clutch fluid reservoir
diaphragm will lose its shape from
the negative pressure if the fluid
level goes down too far. Be sure to
return the diaphragm to its original
shape before installing it into the
brake or clutch fluid reservoir.


Be careful that water does not en-
ter the brake or clutch fluid reser-
voir when refilling. Water will
significantly lower the boiling point
of the fluid and may result in vapor
lock.


Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.


As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if the
brake fluid level goes down sud-
denly, have a Yamaha dealer
check the cause.
EAU03984
Changing the brake and
clutch fluids Have a Yamaha dealer change the
brake and clutch fluids at the intervals
specified in the NOTE after the periodic
maintenance and lubrication chart. In
addition, have the oil seals of the brake
and clutch master cylinders and cali-
pers as well as the brake and clutch
hoses replaced at the intervals listed
below or whenever they are damaged
or leaking.

Oil seals: Replace every two
years.


Brake and clutch hoses: Replace
every four years.
