Adjusting the shift pedal
position
1. Distance between shift pedal and footrest
The top of the shift pedal should be
positioned approximately 65 mm
(2.56 in) below the top of the footrest
as shown. Periodically check the shift
pedal position and, if necessary, have
a Yamaha dealer adjust it.

Adjusting the rear brake light
switch
1. Rear brake light switch adjusting nut
2. Brake light switch
The rear brake light, which is activa-
ted by the brake pedal, should come
on just before braking takes effect. If
necessary, adjust the rear brake light
switch as follows.
Turn the rear brake light switch adjus-
ting nut while holding the rear brake
light switch in place. To make the bra-
ke light come on earlier, turn the
adjusting nut in direction (a). To make
the brake light come on later, turn the
adjusting nut in direction (b).

Rear brake pads
Each rear brake pad is provided with
a wear indicator groove, which allows
you to check the brake pad wear wit-

Check the brake pad wear as follows.
1. Remove the brake caliper bolt,
and then tilt the caliper forward to
inspect the wear indicator groo-
ve. If a brake pad has worn to the
point that the wear indicator gro-
ove has almost disappeared,
have a Yamaha dealer replace
the brake pads as a set.

Insufficient brake fluid may allow air
to enter the brake system, possibly
causing it to become ineffective.
Before riding, check that the brake
fluid is above the minimum level mark
and replenish if necessary. A low bra-
ke fluid level may indicate worn brake
pads and/or brake system leakage. If
the brake fluid level is low, be sure to
check the brake pads for wear and
the brake system for leakage.
Observe these precautions:
●When checking the fluid level,
make sure that the top of the bra-
ke fluid reservoir is level.
●Use only the recommended qua-
lity brake fluid, otherwise the rub-
ber seals may deteriorate, cau-
sing leakage and poor braking
performance.
●Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performan-
ce.
●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 vapor
lock.
●Brake fluid may deteriorate pain-
ted surfaces or plastic parts.
Always clean up spilled fluid
immediately.
●As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if
the brake fluid level goes down
suddenly, have a Yamaha dealer
check the cause.
EAU22731
Changing the brake fluid
Have a Yamaha dealer change the
brake fluid at the intervals specified in
the TIP after the periodic maintenan-
ce and lubrication chart. In addition,
have the oil seals of the master cylin-
ders 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.

Drive chain slack
The drive chain slack should be chec-
ked before each ride and adjusted if
necessary.
EAU22783
To check the drive chain slack
1. Drive chain slack
1. Place the motorcycle on the
sidestand.
TIP
When checking and adjusting the dri-
ve chain slack, there should be no
weight on the motorcycle.
2. Shift the transmission into the
neutral position.3. Move the rear wheel by pushing
the motorcycle to locate the tigh-
test portion of the drive chain,
and then measure the drive chain
slack as shown.
4. If the drive chain slack is inco-
rrect, adjust it as follows.
TIP
When checking the drive chain slack,
the chain tensioner should not be tou-
ching the drive chain.
EAU22921
To adjust the drive chain slack
1. Remove the cotter pin from the
axle nut, and then loosen the axle
nut.
2. Loosen the chain puller locknut
at each end of the swingarm.
3. To tighten the drive chain, turn
the drive chain slack adjusting
bolt on each end side of the
swingarm in direction (a). To loo-
sen the drive chain, turn the
adjusting bolt on each side of theswingarm in direction (b), and
then push the rear wheel forward.
NOTICE: Improper drive chain
slack will overload the engine
as well as other vital parts of
the motorcycle and can lead to
chain slippage or breakage. To
prevent this from occurring,
keep the drive chain slack wit-
hin the specified limits.
[ECA10571]
TIP
Using the alignment marks on each
side of the swingarm, make sure that
both chain pullers are in the same
position for proper wheel alignment.

Cleaning and lubricating the
drive chain
The drive chain must be cleaned and
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.
ECA10581
The drive chain must be lubricated
after washing the motorcycle and
riding in the rain.
1. To prevent damaging the O-rings,
do not clean the drive chain with
steam cleaners, high-pressure
washers or inappropriate sol-
vents. NOTICE: To prevent
damaging the O-rings, do not
clean the drive chain with ste-
am cleaners, high-pressure
washers or inappropriate sol-
vents.

The operation of all control cables
and the condition of the cables
should be checked before each ride,
and the cables and cable ends should
be lubricated if necessary. If a cable is
damaged or does not move smoothly,
have a Yamaha dealer check or repla-
ce it. WARNING! Damage to the
outer sheath may interfere with
proper cable operation and will
cause the inner cable to rust.
Replace a damaged cable as soon
as possible to prevent unsafe con-
ditions.
