Adjusting the clutch lever free
play The clutch lever free play should mea-
sure 10.0–15.0 mm (0.39–0.59 in) as
shown. Periodically check the clutch le-
ver free play and, if necessary, adjust it
as follows.
To increase the clutch lever free play,
turn the clutch lever free play adjusting
bolt in direction (a). To decrease the
clutch lever free play, turn the adjusting
bolt in direction (b).
TIPIf the specified free play cannot be ob-
tained as described above or if the
clutch does not operate correctly, have
a Yamaha dealer check the internal
clutch mechanism.
EAU37913
Checking the brake lever free
play There should be no free play at the
brake lever end. If there is free play,
have a Yamaha dealer inspect the
brake system.
WARNING
EWA14211
A soft or spongy feeling in the brake
lever can indicate the presence of air
in the hydraulic system. If there is air
in the hydraulic system, have a
Yamaha dealer bleed the system be-
fore operating the vehicle. Air in the
hydraulic system will diminish the

Brake light switches (for ABS
models) The brake light, which is activated by
the brake pedal and brake lever, should
come on just before braking takes ef-
fect. If necessary, have a Yamaha deal-
er adjust the brake light switches.
EAU50760
Brake light switches (for non-
ABS models) The brake light, which is activated by
the brake pedal and brake lever, should
come on just before braking takes ef-
fect. If necessary, adjust the rear brake
light switch as follows, but the front
brake light switch should be adjusted
by a Yamaha dealer.
Turn the rear brake light switch adjust-
ing nut while holding the rear brake light
switch in place. To make the brake 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).1. Rear brake light switch

Checking the front and rear
brake pads The front and rear brake pads must be
checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart.
EAU36890
Front brake pads
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 tothe point that a wear indicator almost
touches the brake disc, have a Yamaha
dealer replace the brake pads as a set.
EAU46291
Rear brake pads
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.
EAU43112
Checking the brake fluid level Before riding, check that the brake fluid
is above the minimum level mark.
Check the brake fluid level with the top
of the reservoir level. Replenish the
brake fluid if necessary.

TIPThe rear brake fluid reservoir is located
behind panel C. (See page 6-8.)
WARNING
EWA16010
Improper maintenance can result in
loss of braking ability. Observe
these precautions:●
Insufficient brake fluid may al-
low air to enter the brake sys-
tem, reducing braking
performance.
●
Clean the filler cap before re-
moving. Use only DOT 4 brake
fluid from a sealed container.
●
Use only the specified brake flu-
id; otherwise, the rubber seals
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 or dust
does not enter the brake fluid
reservoir when refilling. Water
will significantly lower the boil-
ing point of the fluid and may re- sult in vapor lock, and dirt may
clog the ABS hydraulic unit
valves.
NOTICE
ECA17640
Brake fluid may damage painted sur-
faces or plastic parts. Always clean
up 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 fluid Have a Yamaha dealer change the
brake fluid at the intervals specified in
the TIP after the periodic maintenance
and lubrication chart. In addition, have
the oil seals of the master cylinders and
calipers as well as the brake hoses re-
placed at the intervals listed below or
whenever they are damaged or leak-
ing.●
Oil seals: Replace every two
years.
●
Brake hoses: Replace every four
years.

Drive chain slack The drive chain slack should be
checked before each ride and adjusted
if necessary.
EAU22794
To check the drive chain slack1. Place the motorcycle on the cen- terstand.
2. Shift the transmission into the neu- tral position.
3. Measure the drive chain slack as shown.
4. If the drive chain slack is incorrect, adjust it as follows.
EAU49312
To adjust the drive chain slack
Consult a Yamaha dealer before ad-
justing the drive chain slack.1. Take the motorcycle off the center- stand, and then put the sidestand
down.
2. Loosen the axle nut and the lock- nut on each side of the swingarm.
3. Place the motorcycle on the cen- terstand.
4. To tighten the drive chain, turn the drive chain slack adjusting bolt on
each side of the swingarm in direc-
tion (a). To loosen the drive chain,
turn the adjusting bolt on each side
of the swingarm in direction (b),
and then push the rear wheel for-
ward. NOTICE: Improper drive
chain slack will overload the en-
gine 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 with-
in the specified limits.

TIPUsing the alignment marks on each
side of the swingarm, make sure that
both drive chain pullers are in the same
position for proper wheel alignment.5. Take the motorcycle off the center-stand, and then put the sidestand
down.
6. Tighten the axle nut, then the lock- nuts to the specified torques. 7. Make sure that the drive chain pull-
ers are in the same position, the
drive chain slack is correct, and
the drive chain moves smoothly.

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.NOTICE
ECA10583
The drive chain must be lubricated
after washing the motorcycle, riding
in the rain or riding in wet areas.1. Clean the drive chain with kero-sene and a small soft brush.
NOTICE: To prevent damaging
the O-rings, do not clean the
drive chain with steam cleaners,
high-pressure washers or inap-
propriate solvents.
[ECA11121]
2. Wipe the drive chain dry.
3. Thoroughly lubricate the drive chain with a special O-ring chain
lubricant. NOTICE: Do not use

cants for the drive chain, as they

Checking and lubricating the
cables The operation of all control cables and
the condition of the cables should be
checked before each ride, and the ca-
bles and cable ends should be lubricat-
ed if necessary. If a cable is damaged
or does not move smoothly, have a
Yamaha dealer check or replace it.
WARNING! Damage to the outer
housing of cables may result in in-
ternal rusting and cause interfer-
ence with cable movement. Replace
damaged cables as soon as possi-
ble to prevent unsafe conditions.[EWA10711] EAU23114
Checking and lubricating the
throttle grip and cable The operation of the throttle grip should
be checked before each ride. In addi-
tion, the cable should be lubricated by a
Yamaha dealer at the intervals speci-
fied in the periodic maintenance chart.
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
completely protect the cable from water
entry. Therefore, use care not to 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.
Recommended lubricant:
Yamaha Chain and Cable Lube or
engine oil
