checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart.
EAU36891
Front brake pad s
Each front brake pad is provided with
wear indicators, which allows you to
check the brake pad wear without hav-
ing to disassemble the brake. To check
the brake pad wear, check the position
of the wear indicators while applying
the brake. If a brake pad has worn to
the point that a wear indicator almost touches the brake disc, have a
Yamaha dealer replace the brake pads
as a set.
EAU46292
Rear
brake pa ds
Each rear brake pad is provided with
wear indicator grooves, which allow
you to check the brake pad wear with-
out having to disassemble the brake.
To check the brake pad wear, check
the wear indicator grooves. If a brake
pad has worn to the point that a wear
indicator groove almost appears, have
a Yamaha dealer replace the brake
pads as a set.

Drive chain slackThe drive chain slack should be
checked before each ride and adjusted
if necessary.

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. Measure the drive chain slack as shown.Drive chain slack:5.0–15.0 mm (0.20–0.59 in)

adjust it as follows.
EAU57970
To a djust the d rive chain slack
Consult a Yamaha dealer before ad-
justing the drive chain slack. 1. Loosen the axle nut and the lock- nut on each side of the swingarm. 2. To tighten the drive chain, turn the
drive chain slack adjusting bolt on
each side of the swingarm in di-
rection (a). To loosen the drive
chain, turn the adjusting bolt on
each side of the swingarm in di-
rection (b), and then push the rear
wheel forward. NOTICE: Improp-
er drive chain slack will over-
loa d the en gine as well as other
vital parts of the motorcycle an d
can lead to chain slippa ge or
b reakag e. If the drive chain
slack is more than 25.0 mm
(0.98 in), the chain can d amage
the frame, swin garm, an d other
parts. To prevent this from oc- currin
g, keep the drive chain
slack within the specified limits.

TIPUsing the alignment marks and notch
on each side of the swingarm, make
sure that both drive chain pullers are in
the same position for proper wheel
alignment.

The throttle cable is equipped with a
rubber cover. Make sure that the cover
is securely installed. Even though the
cover is installed correctly, it does not

pour water directly onto the cover or
cable when washing the vehicle. If the
cable or cover becomes dirty, wipe
clean with a moist cloth.
