Spoke wheels
To maximize the performance, durabil-
ity, and safe operation of your motorcy-
cle, note the following points regarding
the specified wheels.

The wheel rims should be checked
for cracks, bends or warpage, and
the spokes for looseness or dam-
age before each ride. If any dam-
age is found, have a Yamaha
dealer replace the wheel. Do not
attempt even the smallest repair to
the wheel. A deformed or cracked
wheel must be replaced.

The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced. An
unbalanced wheel can result in
poor performance, adverse han-
dling characteristics, and a short-
ened tire life.

Ride at moderate speeds after
changing a tire since the tire sur-
face must first be “broken in” for it
to develop its optimal characteris-
tics.

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.
1. Slide the rubber cover back at the
clutch lever.
2. Loosen the locknut.
3. To increase the clutch lever free
play, turn the clutch lever free play
adjusting bolt in direction (a). Todecrease the clutch lever free play,
turn the adjusting bolt in direction
(b).
TIP

If the specified clutch lever free play
could be obtained as described above,
skip steps 4–7.
4. Fully turn the adjusting bolt in di-
rection (a) to loosen the clutch ca-
ble.
5. Loosen the locknut further down
the clutch cable.

Adjusting the brake lever free
play
The brake lever free play should mea-
sure 5.0–8.0 mm (0.20–0.31 in) as
shown. Periodically check the brake le-
ver free play and, if necessary, adjust it
as follows.
1. Loosen the locknut at the brake le-
ver.
2. To increase the brake lever free
play, turn the brake lever free play

decrease the brake lever free play,
turn the adjusting screw in direc-tion (b).
3. Tighten the locknut.
WARNING

EWA10630

After adjusting the brake lever
free play, check the free play
and make sure that the brake is
working properly.

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 hy-
draulic system, have a Yamaha
dealer bleed the system before
operating the motorcycle. Air in
the hydraulic system will dimin-
ish the braking performance,
which may result in loss of con-
trol and an accident.

Checking the brake fluid level
Front brake
Rear brake
Insufficient brake fluid may allow air to
enter the brake system, possibly caus-
ing it to become ineffective.
Before riding, check that the brake fluid
is above the minimum level mark and
replenish if necessary. A low brake 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 brake
fluid reservoir is level.

Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking perfor-
mance.

Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performance.

Be careful that water does not en-ter the brake fluid reservoir when
refilling. Water will significantly
lower the boiling point of the fluid
and may result in vapor lock.

Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.

As the brake pads wear, it is nor-
mal for the brake fluid level to grad-
ually go down. However, if the
brake fluid level goes down sud-
denly, have a Yamaha dealer
check the cause.

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.
EAU47221
To check the drive chain slack
1. Place the motorcycle on the side-
stand.
TIP

When checking and adjusting the drive
chain slack, there should be no weight
on the motorcycle.
2. Shift the transmission into the neu-
tral position.
3. Push on the drive chain at the cen-
ter point between the chain ten-
sioner and the chain support
mounting bolt with a force of 50 N
(5.0 kgf, 36 lbf).
4. Measure drive chain slack be-
tween the swingarm and the top of
the chain link closest to the swing-
arm as shown.5. If the drive chain slack is incorrect,
adjust it as follows.
EAU22943
To adjust 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 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.

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

ECA10581
The drive chain must be lubricated
after washing the motorcycle and
riding in the rain.
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.
