3. If the oil is below the brim of the
filler hole, add sufficient oil of the
recommended type to raise it to
the correct level.
4. Check the gasket for damage, and replace it if necessary.
5. Install the final gear oil filler bolt and its gasket, and then tighten
the bolt to the specified torque.
To chan ge the final gear oil
1. Place the vehicle on a level surfa- ce.
2. Place an oil pan under the final gear case to collect the used oil.
3. Remove the final gear oil filler bolt, the final gear oil drain bolt and
their gasket to drain the oil from
the final gear case. 4. Install the final gear oil drain bolt
and its new gasket, and then tight-
en the bolt to the specified torque.
5. Refill with the recommended final gear oil to the brim of the filler
hole.
6. Check the oil filler bolt gasket for damage, and replace it if neces-
sary.
7. Install the oil filler bolt and its gas- ket, and then tighten the bolt to
the specified torque.
8. Check the final gear case for oil leakage. If oil is leaking, check for
the cause.

Coolant
The coolant level should be checked
regularly. In addition, the coolant must
be changed at the intervals specified in
the periodic maintenance chart.
TIP
If genuine Yamaha coolant is not avail-
able, use an ethylene glycol antifreeze
containing corrosion inhibitors for alu-
minum engines and mix with distilled
water at a 1:1 ratio.
EAU54164To check the coolant level
1. Wait for the engine to cool. The coolant level will vary with engine
temperature.
2. Place the vehicle on the center- stand.
3. Remove the left cowling vent pan- el. (See page 3-37.)
4. Look at the coolant reservoir. 5. If the coolant is at or below the mi-
nimum level mark, remove the
coolant reservoir cap. WARNING!
Remove only the coolant reser-
voir cap. Never attempt to re-
move the ra diator cap when the
en gine is hot.
[EWA15162]
6. Add coolant or distilled water to
raise the coolant to the maximum
level mark, and install the coolant
reservoir cap. NOTICE: If coolant
is not availab le, use distille d wa-
ter or soft tap water instea d. Do
not use har d water or salt water
since it is harmful to the en gine.
If water has been used instead
of coolant, replace it with cool-
ant as soon as possi ble, other-
wise the coolin g system will not
b e protecte d a gainst frost an d
corrosion. If water has b een
a dde d to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant as
soon as possi ble, otherwise the
effectiveness of the coolant will
b e red uced.

Cleanin
g the air filter element
The air filter element should be cleaned
or replaced at the intervals specified in
the periodic maintenance and lubrica-
tion chart. Clean or, if necessary, re-
place the air filter element more
frequently if you are riding in unusually
wet or dusty areas.
1. Remove panel B. (See page 6-7.)
2. Remove the intake air shroud by removing the screw and the quick
fastener screws.
3. Remove the air filter case cover by removing the screws.
4. Pull the air filter element out.

remove most of the dust and dirt,
and then blow the remaining dirt
out with compressed air as
shown. If the air filter element is
damaged, replace it.
6. Insert the air filter element into the air filter case. NOTICE: Make
sure that the air filter element is
properly seate d in the air filter
case. The en gine shoul d never

installing the screws. NOTICE:
Make sure that the fuel tank

Valve clearance
The valves are an important engine
component, and since valve clearance
changes with use, they must be
checked and adjusted at the intervals
specified in the periodic maintenance
chart. Unadjusted valves can result in
improper air-fuel mixture, engine
noise, and eventually engine damage.
To prevent this from occurring, have
your Yamaha dealer check and adjust
the valve clearance at regular intervals.
TIP
This service must be performed when
the engine is cold.
EAU64410
Tires
Tires are the only contact between the
vehicle and the road. Safety in all con-
ditions of riding depends on a relatively
small area of road contact. Therefore, it
is essential to maintain the tires in good
condition at all times and replace them
at the appropriate time with the speci-
fied tires.
Tire air pressure
The tire air pressure should be
checked and, if necessary, adjusted
before each ride.
WARNING
EWA10504
Operation of this vehicle with im-
proper tire pressure may cause se-
vere injury or d eath from loss of
control. The tire air pressure must be
checked and a djuste d on col d
tires (i.e., when the temperature
of the tires equals the am bient
temperature).
The tire air pressure must be
a d juste d in accor dance with the
ri din g speed and with the total
wei ght of ri der, passen ger, car-
g o, an d accessories approve d
for this mo del.

WARNING
EWA10512
Never overloa d your vehicle. Opera-
tion of an overloa ded vehicle coul d
cause an acci dent.
Tire inspection
The tires must be checked before each
ride. If the center tread depth reaches
the specified limit, if the tire has a nail
or glass fragments in it, or if the side-
wall is cracked, have a Yamaha dealer
replace the tire immediately.
TIP
The tire tread depth limits may differ
from country to country. Always com-
ply with the local regulations.
WARNING
EWA10472
Have a Yamaha dealer replace
excessively worn tires. Besi des
b ein g ille gal, operatin g the vehi-
cle with excessively worn tires
d ecreases ri din g sta bility an d
can lead to loss of control.
The replacement of all wheel
and b rake-relate d parts, inclu d-
in g the tires, shoul d b e left to a
Yamaha dealer, who has the
necessary professional knowl-
e dg e an d experience to d o so.
Ride at mo derate spee ds after
chan gin g a tire since the tire
surface must first b e “broken

characteristics.

6 This model is equipped with tubeless
tires and tire air valves.
Tires age, even if they have not been
used or have only been used occasion-
ally. Cracking of the tread and sidewall
rubber, sometimes accompanied by
carcass deformation, is an evidence of
ageing. Old and aged tires shall be
checked by tire specialists to ascertain
their suitability for further use.
WARNING
