Storage compartment This storage compartment is designed
to hold an optional genuine Yamaha
U-LOCK. (Other locks may not fit.)
When placing a U-LOCK in the stor-
age compartment, securely fasten it
with the straps. When the U-LOCK is
not in the storage compartment, be
sure to secure the straps to prevent
losing them.When storing the owner’s manual or
other documents in the storage com-
partment, be sure to wrap them in a
plastic bag so that they will not get
wet. When washing the motorcycle,
be careful not to let any water enter
the storage compartment.

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.

out, especially when riding in dusty or
wet areas. Service the drive chain as
follows.
EC000097
CAUTION:_ The drive chain must be lubricated
after washing the motorcycle or
riding in the rain. _1. Clean the drive chain with kero-
