Engine oil and oil filter car-
tridgeThe engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter car-
tridge replaced at the intervals speci-
fied in the periodic maintenance and
lubrication chart.
To check the engine oil level
1. Place the vehicle on a level surfa- ce and hold it in an upright posi-
tion. A slight tilt to the side can
result in a false reading.
2. Start the engine, warm it up for several minutes, and then turn it
off.
3. Wait a few minutes for the oil level to settle for an accurate reading,
and then check the oil level
through the check window locat-
ed at the bottom-left side of the
crankcase.TIPThe engine oil should be between the
minimum and maximum level marks.
4. If the engine oil is at or below theminimum level mark, add suffi-
cient oil of the recommended type
to raise it to the correct level.TIPCheck the oil filler cap O-ring for dam-
age, and replace it if necessary.To change the engine oil1. Start the engine, warm it up for several minutes, and then turn it
off.
2. Place an oil pan under the engine to collect the used oil.

playMeasure the clutch lever free play as
shown.
Periodically check the clutch lever free
play and, if necessary, adjust it as fol-
lows.
To increase the clutch lever free play,
turn the clutch lever free play adjusting
bolt at the clutch lever in direction (a).
To decrease the clutch lever free play,
turn the adjusting bolt in direction (b).
TIPIf the specified clutch lever free play
cannot be obtained as described
above, proceed as follows.1. Fully turn the adjusting bolt at the
clutch lever in direction (a) to loos-
en the clutch cable.
2. Remove cowling B. (See page 7-9.)
3. Loosen the locknut further down the clutch cable.
4. To increase the clutch lever free play, turn the clutch lever free play
adjusting nut in direction (a). To
decrease the clutch lever free
play, turn the adjusting nut in di-
rection (b).

Checking the brake lever free
playThere should be no free play at the
brake lever end. If there is free play,
have a Yamaha dealer inspect the
brake system.
WARNING
EWA14212
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 braking performance, which may re-
sult in loss of control and an acci-
dent.

Brake light switchesThe brake light should come on just
before braking takes effect. The brake
light is activated by switches connect-
ed to the brake lever and brake pedal.
Since the brake light switches are
components of the anti-lock brake sys-
tem, they should only be serviced by a
Yamaha dealer.

Checking the front and rear
brake padsThe front and rear brake pads must be
checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart.
EAU36891
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 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 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.

Checking the brake fluid levelBefore riding, check that the brake fluid
is above the minimum level mark.TIPMake sure the reservoir is parallel to
the ground when checking.NOTICE
ECA17641
Brake fluid may damage painted
surfaces or plastic parts. Always
clean up spilled fluid immediately.Front brakeRear brake
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 or brake
system 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 rid-
ing.
WARNING
EWA15991
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 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.

Changing the brake fluidHave a Yamaha dealer change the
brake fluid every 2 years. In addition,
have the seals of the master cylinders
and brake calipers, as well as the brake
hoses replaced at the intervals listed
below or sooner if they are damaged or
leaking. Brake seals: every 2 years
 Brake hoses: every 4 years

Drive chain slackThe drive chain slack should be
checked before each ride and adjusted
if necessary.
EAU2277G
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. 4. If the drive chain slack is incorrect,
adjust it as follows. NOTICE: Im-
proper drive chain slack will
overload the engine as well as
other vital parts of the motorcy-
cle and can lead to chain slip-
page or breakage. If the drive
chain slack is more than 35.0
mm (1.38 in), the chain can dam-
age the frame, swingarm, and
other parts. To prevent this from
occurring, keep the drive chain
slack within the specified limits.
[ECA17791]
EAU74260
To adjust the drive 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.

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.3. Tighten the axle nut, then the lock-nuts to their specified torques. 4. Make sure that the drive chain
pullers are in the same position,
the drive chain slack is correct,
and the drive chain moves
smoothly.
