●
In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a high-
er quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.
●
Make sure that no foreign mate-
rial enters the crankcase.
10. Start the engine, and then let it idlefor several minutes while checking
it for oil leakage. If oil is leaking, im-
mediately turn the engine off and
check for the cause.TIPAfter the engine is started, the engine
oil level warning light should go off if the
oil level is sufficient.
NOTICE
ECA10401
If the oil level warning light flickers
or remains on even if the oil level is
correct, immediately turn the engine
off and have a Yamaha dealer check
the vehicle.11. Turn the engine off, and thencheck the oil level and correct it if
necessary.
EAU20016
Final gear oil The final gear case must be checked
for oil leakage before each ride. If any
leakage is found, have a Yamaha deal-
er check and repair the vehicle. In addi-
tion, the final gear oil level must be
checked and the oil changed as follows
at the intervals specified in the periodic
maintenance and lubrication chart.
WARNING
EWA10370
●
Make sure that no foreign mate-
rial enters the final gear case.
●
Make sure that no oil gets on the
tire or wheel.
To check the final gear oil level1. Place the vehicle on the center- stand.TIPMake sure that the vehicle is positioned
straight up when checking the oil level.
A slight tilt to the side can result in a
false reading.2. Remove the final gear oil filler boltand its gasket, and then check the
oil level in the final gear case.

TIPThe oil level should be at the brim of the
filler hole.3. If the oil is below the brim of the fill-er hole, add sufficient oil of the rec-
ommended 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 change the final gear oil
1. Place the vehicle on a level sur- face.
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.

Coolant The coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU54160
To check the coolant level1. Place the vehicle on the center- stand.TIP●
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
●
Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.
2. Remove the left cowling vent pan-el. (See page 3-37.)
3. Check the coolant level in the cool- ant reservoir.TIPThe coolant should be between the
minimum and maximum level marks.
4. If the coolant is at or below theminimum level mark, remove the
coolant reservoir cap.
5. Add coolant or distilled water to raise the coolant to the maximum
level mark, and install the coolant reservoir cap.
WARNING! Re-
move only the coolant reservoir
cap. Never attempt to remove
the radiator cap when the en-
gine is hot.
[EWA15161]
NOTICE: If
coolant is not available, use dis-
tilled water or soft tap water in-
stead. Do not use hard water or
salt water since it is harmful to
the engine. If water has been
used instead of coolant, replace
it with coolant as soon as possi-
ble, otherwise the cooling sys-
tem will not be protected
against frost and corrosion. If
water has been added to the
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possible,
otherwise the effectiveness of
the coolant will be reduced.

Cleaning 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 6-8.)
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.

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 prop-
erly seated in the air filter case.
The engine should never be op-
erated without the air filter ele-
ment installed, otherwise the
piston(s) and/or cylinder(s) may
become excessively worn.

Checking the throttle grip free
play The throttle grip free play should mea-
sure 3.0–5.0 mm (0.12–0.20 in) at the
inner edge of the throttle grip. Periodi-
cally check the throttle grip free play
and, if necessary, have a Yamaha deal-
er adjust it.

Valve clearance The valve clearance changes with use,
resulting in improper air-fuel mixture

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
EWA10503
Operation of this vehicle with im-
proper tire pressure may cause se-
vere injury or death from loss of
control.●
The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the temperature
of the tires equals the ambient
temperature).
●
The tire air pressure must be ad-
justed in accordance with the
riding speed and with the total

WARNING
EWA10511
Never overload your vehicle. Opera-
tion of an overloaded vehicle could
cause an accident.
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 sidewall is
cracked, have a Yamaha dealer re-
place the tire immediately.TIPThe tire tread depth limits may differ
from country to country. Always comply
with the local regulations.
WARNING
EWA10471
●
Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the vehi-
cle with excessively worn tires
decreases riding stability and
can lead to loss of control.
●
The replacement of all wheel
and brake-related parts, includ-
ing the tires, should be left to a
Yamaha dealer, who has the necessary professional knowl-
edge and experience to do so.
●
Ride at moderate speeds after
changing a tire since the tire
surface must first be “broken
in” for it to develop its optimal
characteristics.

6Tire information
This motorcycle is equipped with tube-
less tires, tire air valves and cast
wheels.
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
EWA10481
●
The front and rear tires should
be of the same make and de-
sign, otherwise the handling
characteristics of the motorcy-
cle 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 to
avoid tire deflation during a
high-speed ride.
After extensive tests, only the tires list-
ed below have been approved for this
model by Yamaha Motor Co., Ltd.
WARNING
EWA10600
This motorcycle is fitted with super-
high-speed tires. Note the following
points in order to make the most ef-
ficient use of these tires.●
Use only the specified replace-
ment tires. Other tires may run
the danger of bursting at super
high speeds.
