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 ofheat.
NOTICE
ECA10701
Use only unleaded gasoline. The use
of leaded gasoline will cause unre-
pairable damage to the catalytic
converter.

NOTICE: Keep the
following points in mind when using
the storage compartment. Since the storage compartment accumulates
heat when exposed to the sun and/
or the engine heat, do not store any-
thing susceptible to heat, consum-
ables or flammable items inside it.
To avoid humidity from spreading
through the storage compartment,
wrap wet articles in a plastic bag be-
fore storing them in the compart-

9characteristics of the vehicle
may be different, which could
lead to an accident.
Always make sure that the valve
caps are securely installed to
prevent air pressure leakage.
Use only the tire valves and
valve cores listed below toavoid tire deflation during a ride.
After extensive tests, only the tires list-
ed below have been approved for this
model by Yamaha Motor Co., Ltd.

Cast wheels To maximize the performance, durabil-
ity, and safe operation of your vehicle,
note the following points regarding the
specified wheels.
The wheel rims should be checked
for cracks, bends, warpage or oth-
er damage before each ride. If any
damage 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.
After repairing or replacing the
front tire, tighten the valve stem nut
and locknut to the specified
torques.

There should be no free play at thebrake lever ends. 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
braking performance, which may re-
sult in loss of control and an acci-dent.

Adjusting the rear brake lock
cable Rear brake lock cable adjustment may
be required if the rear brake lock lever
does not hold properly. When the rear
brake lock lever is not in use, the rear
brake lock cable length should mea-
sure 43 mm–45 mm (1.69 in–1.77 in) at
the rear brake caliper.
Periodically check the rear brake lock
cable length and, if necessary, adjust it
as follows.
To increase the rear brake lock cable
length, turn the adjusting nut at the rear
brake caliper in direction (a). To de-crease the rear brake lock cable length,
turn the adjusting nut in direction (b).
WARNING! If proper adjustment
cannot be obtained as described,
have a Yamaha dealer make this ad-
justment.
[EWA16150]
Check that the rear brake lock is re-
leased, and then make sure that the
rear wheel could rotate smoothly.
EAU52291
Checking the rear brake lock The rear brake lock must be checked at
the intervals specified in the periodic
maintenance and lubrication chart.
1. Adjust the rear brake lock cable.
2. Apply the rear brake lock, and then pushing the vehicle for properly
locks the rear brake lock.
3. The rear brake lock caliper is pro- vided with a wear indicator, which
allows you to check the rear brake
lock pads. To check the rear brake
lock pads, check the position of the
indicator while applying the rear
brake lock lever. If the indicator
has passed the wear indicator
groove, have a Yamaha dealer
check the rear brake lock.
4. Make sure that there is no tears and cracks on the rubber boot.

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.
Front brakeRear brake
WARNING
EWA15990
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 sealsmay 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 vaporlock.
NOTICE
ECA17640
Brake fluid may damage painted sur-
faces or plastic parts. Always cleanup 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.
