Brake li ght switchesThe brake light should come on just
before braking takes effect. The brake
light is activated by switches connect-
ed to the brake lever and brake pedal.
Since the brake light switches are
components of the anti-lock brake sys-
tem, they should only be serviced by a
Yamaha dealer.

Brake flui d may damag e painted
surfaces or plastic parts. Always
clean up spille d flui d imme diately.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
system 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.
EAU22734
Chan gin g the brake flui dHave a Yamaha dealer change the
brake fluid every 2 years. In addition,
have the seals of the master cylinders
and brake calipers, as well as the brake
hoses replaced at the intervals listed
below or sooner if they are damaged or
leaking.
Brake seals: every 2 years
Brake hoses: every 4 years

Drive chain slackThe drive chain slack should be
checked before each ride and adjusted
if necessary.
EAU60046
To check the drive chain slack
1. Place the motorcycle on the side- stand.TIPWhen checking and adjusting the drive
chain slack, there should be no weight
on the motorcycle.2. Shift the transmission into the neutral position.
3. Push down on the drive chain un- der the end of the drive chain
guard.
4. Measure distance A between the drive chain guard and the center
of the chain as shown. 5. If distance A is incorrect, adjust it
as follows. NOTICE: Improper
d rive chain slack will overloa d
the en gine as well as other vital
parts of the motorcycle an d can
lea d to chain slippa ge or b reak-
a g e. If d istance A is more than
58.0 mm (2.28 in), the chain can
d amag e the frame, swin garm,
an d other parts. To prevent this
from occurrin g, keep the drive
chain slack within the specifie d
limits.

Consult a Yamaha dealer before ad-
justing the drive chain slack. 1. Loosen the locknut at each end of the swingarm, and then loosen the
axle nut.
2. To tighten the drive chain, turn the drive chain slack adjusting nut at
each end of the swingarm in direc-
tion (a). To loosen the drive chain,
turn the adjusting nut at each end
of the swingarm in direction (b),
and then push the rear wheel for-
ward.

TIPUsing the alignment marks on each
side of the swingarm, make sure that
both drive chain slack adjusting plates
are in the same position for proper
wheel alignment.
3. Tighten the axle nut, and then
tighten the locknuts to the speci-
fied torques.
4. Make sure that the drive chain slack adjusting plates are in the
same position, the drive chain
slack is correct, and the drive
chain moves smoothly.

lubricated at the intervals specified in
the periodic maintenance and lubrica-
tion chart, otherwise it will quickly wear
out, especially when riding in dusty or
wet areas. Service the drive chain as
follows.NOTICE

The drive chain must be lu bricated
after washin g the motorcycle, ri din g
