EAU00683
Operating the motorcycle with ex-
cessively worn tires decrease riding
stability and can lead to loss of con-
trol. Have excessively worn tires re-
placed by a Yamaha dealer
immediately. Brakes, tires, and re-
lated wheel parts replacement
should be left to a Yamaha Service
Technician.
EAU00687
Wheels
To ensure maximum performance,
long service, and safe operation, note
the following:
lAlways inspect the wheels before
a ride. Check for cracks, bends, or
warpage of the wheels. If any ab-
normal condition exists in a wheel,
consult a Yamaha dealer. Do not
attempt even small repairs to the
wheel. If a wheel is deformed or
cracked, it must be replaced.
lTires and wheels should be bal-
anced whenever either one is
changed or replaced. Failure to
have a wheel balanced can result
in poor performance, adverse han-
dling characteristics, and short-
ened tire life.
lRide at moderate speeds after
changing a tire since the tire sur-
face must first be broken in for it to
develop its optimal characteristics.
1. Locknut
2. Adjusting bolt
c. Free play
EAU00694
Clutch lever free play
adjustment
The clutch lever free play should be ad-
justed to 2 ~ 3 mm.
1. Loosen the locknut at the clutch le-
ver.
2. Turn the adjusting bolt at the
clutch lever in direction a
to in-
crease free play or in direction b
to decrease free play.
3. Tighten the locknut at the clutch
lever.

a. Pedal height
EAU00712
Rear brake pedal height
adjustment
The top of the brake pedal should be
positioned 40 mm below the top of the
footrest. If not, ask a Yamaha dealer to
adjust it.
EW000109
A soft or spongy feeling in the brake
pedal can indicate the presence of
air in the brake system. This air
must be removed by bleeding the
brake system before the motorcycle
is operated. Air in the system will
cause greatly diminished braking
capability and can result in loss of
control and an accident. Have a
Yamaha dealer inspect and bleed
the system if necessary.
1. Brake light switch
2. Adjusting nut
EAU00713
Brake light switch adjustment
The rear brake light switch is activated
by the brake pedal and is properly ad-
justed when the brake light comes on
just before braking takes effect. To ad-
just the rear brake light switch, hold the
switch body so it does not rotate while
turning the adjusting nut. Turn the ad-
justing nut in direction a
to make the
brake light come on earlier. Turn the
adjusting nut in direction b
to make the
brake light come on later.

Front brake
A wear indicator groove is provided on
each brake pad. This indicator allows
checking of brake pad wear without
disassembling the brake. Inspect the
groove. If the groove has almost disap-
peared, ask a Yamaha dealer to re-
place the pads.

Apply the brake and inspect the wear

ALMOST in contact with the disc plate,
ask a Yamaha dealer to replace the

1. Minimum level mark
EAU00732
Inspecting the brake fluid
level
Insufficient brake fluid may let air enter
the brake system, possibly causing the
brakes to become ineffective.
Before riding, check that the brake fluid
is above the minimum level and fill
when necessary.
Observe these precautions:
lWhen checking the fluid level,
make sure the top of the master
cylinder is level by turning the han-
dlebars.
1. Minimum level mark
l
Use only the designated quality
brake fluid. Otherwise, the rubber
seals may deteriorate, causing
leakage and poor brake perfor-
mance.
NOTE:
If DOT 4 is not available, DOT 3 can be
used.Recommended brake fluid: DOT 4
lRefill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor brake performance.
lBe careful that water does not en-
ter the master cylinder when refill-
ing. Water will significantly lower
the boiling point of the fluid and
may result in vapor lock.
lBrake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.
lHave a Yamaha dealer check the
cause if the brake fluid level goes
down.

Brake fluid replacement
The brake fluid should be replaced only
by trained Yamaha service personnel.
Have the Yamaha dealer replace the
following components during periodic
maintenance or when they are dam-
aged or leaking:
loil seals (every two years)
lbrake hoses (every four years)a. Chain slack
EAU00745
Drive chain slack check
NOTE:
Spin the wheel several times and find
the tightest position of the chain. Check
and/or adjust the chain slack while itÕs
in this tightest position.
Inspect the drive chain when the motor-
cycle is on the centerstand. Check the
slack at the position shown in the illus-
tration. Normal slack is approximately
30 ~ 40 mm. If the slack exceeds
40 mm, adjust.
