If the oil level warning light flickers
or remains on, immediately turn the
engine off and have a Yamaha dealercheck the vehicle.
10. Turn the engine off, and then
check the oil level and correct it if
necessary.
EAU20011
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 must be changed
as follows at the intervals specified in
the periodic maintenance and lubrica-
tion chart.
WARNING
EWA10370
Make sure that no foreign mate-
rial enters the final gear case.
Make sure that no oil gets on thetire or wheel.
To check the final gear oil level
1. Place the vehicle on the center-
stand.
NOTE:
The final gear oil level must be
checked on a cold engine.
Make sure that the vehicle is posi-
tioned straight up when checking
the oil level. A slight tilt to the sidecan result in a false reading.2. Remove the oil filler bolt, and then
check the oil level in the final gear
case.
NOTE:The oil level should be at the brim of thefiller 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. Install the oil filler bolt, and then
tighten it to the specified torque.1. Final gear oil filler bolt

6To change the final gear oil
1. Place an oil pan under the final
gear case to collect the used oil.
2. Remove the oil filler bolt and drain
bolt to drain the oil from the final
gear case.
3. Install the final gear oil drain bolt,
and then tighten it to the specified
torque.
4. Add the recommended final gear
oil to the brim of the filler hole.
5. Install the oil filler bolt, and then
tighten it to the specified torque.6. Check the final gear case for oil
leakage. If oil is leaking, check for
the cause.

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.
EAU39510
To check the coolant level
The coolant level should be checked as
follows before each ride. In addition,
the coolant must be changed at the in-
tervals specified in the periodic mainte-
nance and lubrication chart.
1. Place the vehicle on the center-
stand.NOTE:
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 theside can result in a false reading.
2. Check the coolant level in the cool-
ant reservoir.

NOTE:The coolant should be between theminimum and maximum level marks.
3. If the coolant is at or below the
minimum level mark, remove the
reservoir cap.4. Add coolant or distilled water to
raise the coolant to the maximum
level mark, install the coolant res-
ervoir cap.
CAUTION:
ECA10470
If coolant is not available, use
distilled water or soft tap water
instead. 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 cool-
ant as soon as possible, other-wise the engine may not be
sufficiently cooled and the cool-
ing system 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 ofthe coolant will be reduced.WARNING
EWA10380
Never attempt to remove the radiatorcap when the engine is hot.NOTE:
The radiator fans are automatically
switched on or off according to the
coolant temperature in the radia-
tor.
If the engine overheats, see page6-35 for further instructions.

Cleaning the air filter element The air filter element should be cleaned
at the intervals specified in the periodic
maintenance and lubrication chart.
Clean the air filter element more fre-
quently if you are riding in unusually
wet or dusty areas.
1. Remove panel E. (See page 6-5.)
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.

Make sure that the air filter ele-
ment is properly 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) maybecome excessively worn.

Checking the engine idling
speed The engine idling speed must be
checked as follows and, if necessary,
adjusted by a Yamaha dealer at the in-
tervals specified in the periodic mainte-
nance and lubrication chart.
Start the engine and warm it up for sev-
eral minutes at 1000–2000 r/min while
occasionally revving it to 4000–5000
r/min.NOTE:
The engine is warm when it quickly re-sponds to the throttle.

Tires To maximize the performance, durabil-
ity, and safe operation of your motor-
cycle, note the following points
regarding the specified tires.
Tire air pressure
The tire air pressure should be checked
and, if necessary, adjusted before each
ride.
WARNING
EWA10500
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
weight of rider, passenger, car-
go, and accessories approvedfor this model.

WARNING
EWA11020
Because loading has an enormous
impact on the handling, braking,
performance and safety characteris-
tics of your motorcycle, you should
keep the following precautions in
mind.
NEVER OVERLOAD THE
MOTORCYCLE! Operation of an
overloaded motorcycle may re-
sult in tire damage, loss of con-
trol, or severe injury. Make sure
that the total weight of rider,
passenger, cargo, and accesso-
ries does not exceed the speci-
fied maximum load for the
vehicle.
Do not carry along loosely
packed items, which can shift
during a ride.
Securely pack the heaviest
items close to the center of the
motorcycle and distribute the
weight evenly on both sides.
Adjust the suspension and tire
air pressure with regard to the
load.
Check the tire condition and airpressure before each ride.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.
NOTE:The tire tread depth limits may differ
from country to country. Always complywith the local regulations.

WARNING
EWA10470
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.
Tire informationThis motorcycle is equipped with cast
wheels and tubeless tires with valves.
WARNING
EWA10480
The front and rear tires should
be of the same make and de-
sign, otherwise the handling
characteristics of the motor-
cycle cannot be guaranteed.
After extensive tests, only the
tires listed below have been ap-
proved for this model by
Yamaha Motor Co., Ltd.
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 ahigh-speed ride.
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.
