may deteriorate, causing leak-
age.
Refill with the same type of
brake fluid. Adding a brake fluid
other than DOT 4 may result in a
harmful chemical reaction.
Be careful that water does not
enter the brake fluid reservoir
when refilling. Water will signifi-
cantly lower the boiling point of
the fluid and may result in vaporlock.
NOTICE
ECA17641
Brake fluid may damage painted sur-
faces or plastic parts. Always cleanup spilled fluid immediately.
As the brake pads wear, it is normal for
the brake fluid level to gradually go
down. A low brake fluid level may indi-
cate worn brake pads and/or brake sys-
tem leakage; therefore, be sure to
check the brake pads for wear and the
brake system for leakage. If the brake
fluid level goes down suddenly, have a
Yamaha dealer check the cause before
further riding.

Changing the brake fluidHave a Yamaha dealer change the
brake fluid at the intervals specified in
the periodic maintenance and lubrica-
tion chart. In addition, have the oil seals
of the master cylinders and calipers as
well as the brake hoses replaced at the
intervals listed below or whenever they
are damaged or leaking.
Oil seals: Replace every two
years.
Brake hoses: Replace every four
years.

To check the drive chain slack
1. Place the motorcycle on the sides- tand.TIPWhen checking and adjusting the drive
chain slack, ther e should be no weighton the motorcycle.
2. Shift the transmission into the neu- tral position.
3. Push on the drive chain at the cen- ter point between the chain ten-
sioner and the chain support
mounting bolt with a force of 50 N
(5.0 kgf, 11 lbf).
4. Measure drive chain slack be- tween the swingarm and the top of
the chain link closest to the swing-
arm as shown.
Drive chain slack:8.0–13.0 mm (0.31–0.51 in)
