CanisterThis model is equipped with a canister
to prevent the discharging of fuel vapor
into the atmosphere. Before operating
this vehicle, make sure to check the

Check each hose connection.
Check each hose and canister for
cracks or damage. Replace if
damaged.
Make sure that the canister
breather is not blocked, and if
necessary, clean it.

Engine oil an d oil filter car-
tri dgeThe 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 en gine 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 engine oil level check
window located 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 below the mini-mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.TIPCheck the O-ring for damage, and re-
place it if necessary.

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. Loosen the locknut at the crank- case.
3. 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).
4. Tighten the locknut.

Brake li ght 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.

Brake fluid may damag e painted

clean up spille d flui d imme diately.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
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 riding.
EAU22734
Chan gin g the brake flui dHave 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.
EAU60046
To check the d rive 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. Push down on the drive chain un- der the end of the drive chain
guard.
4. Measure distance A between the drive chain guard and the center
of the chain as shown. 5. If distance A is incorrect, adjust it
as follows. NOTICE: Improper
d rive chain slack will overloa d
the en gine as well as other vital
parts of the motorcycle an d can
lea d to chain slippa ge or b reak-
a g e. If d istance A is more than
40.0 mm (1.57 in), the chain can
d amag e the frame, swin garm,
an d other parts. To prevent this
from occurrin g, keep the drive
chain slack within the specified
limits.

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.
2. To tighten the drive chain, turn the drive chain slack adjusting bolt on
each side of the swingarm in di-
rection (a). To loosen the drive
chain, turn the adjusting bolt on
each side of the swingarm in di-
rection (b), and then push the rear

Cleanin g an d lu bricatin g the
d rive chainThe 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
ECA10584
The drive chain must be lu bricated
after washin g the motorcycle, ri din g
in the rain or ri din g in wet areas.1. Clean the drive chain with kero-
sene and a small soft brush.
NOTICE: To prevent d amaging
