Clutch
Insufficient brake or clutch fluid may al-
low air to enter the brake or clutch sys-
tems, possibly causing them to become
ineffective.
NOTE:
The rear brake fluid reservoir is located
under the rider seat. (See page 3-11.)
Before riding, check that the brake and
clutch fluids are above the minimum
level marks and replenish if necessary.
A low brake or clutch fluid level may in-
dicate brake or clutch system leakage
and/or worn brake pads. If the brake or
clutch levels are low, be sure to check
the brake or clutch systems for leakage
and the brake pads for wear.
Observe these precautions:
● When checking the brake and
clutch fluid levels, make sure that
the top of each reservoir is level.
● Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking or clutch
performance.
● 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.
● 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 grad-
ually go down. However, if the
brake fluid level goes down sud-
denly, have a Yamaha dealer
check the cause.
