Catalytic converter This model is equipped with a catalytic
converter in the exhaust system.
WARNING
EWA10862
The exhaust system is hot after op-
eration. To prevent a fire hazard or
burns:

Do not park the vehicle near
possible fire hazards such as
grass or other materials that
easily burn.


Park the vehicle in a place
where pedestrians or children
are not likely to touch the hot
exhaust system.


Make sure that the exhaust sys-
tem has cooled down before do-
ing any maintenance work.


Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up of
heat.
NOTICE
ECA10701
Use only unleaded gasoline. The use
of leaded gasoline will cause unre-
pairable damage to the catalytic
converter.

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 direction
(b).4. Tighten the locknut.

Brake light switches 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).

6Before 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.
EAU22731
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.
Recommended brake fluid:

Drive chain slack The drive chain slack should be
checked before each ride and adjusted
if necessary.
EAU22773
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 neu-
tral position.
3. Move the rear wheel by pushing
the motorcycle to locate the tight-
est portion of the drive chain, and
then measure the drive chain slack
as shown.4. If the drive chain slack is incorrect,
adjust it as follows.
EAU34315
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. NOTICE: Improper drive
chain slack will overload the en-
gine as well as other vital parts
of the motorcycle and can leadto chain slippage or breakage.
To prevent this from occurring,
keep the drive chain slack with-
in the specified limits.
[ECA10571]
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.

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
engine oil or any other lubri-
cants for the drive chain, as theymay contain substances that
could damage the O-rings.
