To check the engine oil level 1. After warming up the engine, wait a few minutes for the oil to settle.
2. With the vehicle on a level surface, hold it upright for an accurate read-
ing.
3. Check the oil level through the check window located at the bot-
tom of the left-side of the crank-
case.
TIPThe engine oil should be between theminimum and maximum level marks. 4. If the engine oil is at or below the
minimum level mark, remove the
oil filler cap and add oil 5. Check the O-ring for damage, and
replace if necessary.
6. Install the engine oil filler cap.
To change the engine oil (and filter) 1. Start the engine, warm it up for several minutes, and then turn it
off.
2. Place an oil pan under the engine to collect the used oil.
3. Remove the engine oil filler cap, the engine oil drain bolt and its
gasket to drain the oil from the
crankcase.

8. Refill with the specified amount of the recommended engine oil.
TIPWipe off any spilled oil before startingthe engine.
9. Check the O-ring for damage, and then install the oil filler cap. 10. Start the engine and let it idle for
several minutes while checking for
oil leakage. If any leakage is
found, immediately stop the en-
gine and check for the cause.
TIPAfter the engine is started, the oil pres-
sure warning light should go off if the oillevel is sufficient.NOTICE

If the oil pressure warning light flick-
ers or remains on even if the oil level
is correct, immediately turn the en-
gine off and have a Yamaha dealer
check the vehicle.
11. Turn the engine off, wait a few min- utes until the oil settles, and then
check the oil level one last time.

CoolantThe 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.
EAU20096
Checking the coolant level 1. Place the vehicle on a level sur- face and hold it in an upright posi-
tion.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 theside can result in a false reading.
2. Check the coolant level in the cool- ant reservoir.
TIPThe 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. WARNING! Re-
move only the coolant reservoir
cap. Never attempt to remove
the radiator cap when the en-
gine is hot.
[EWA15162]
4. Add coolant to the maximum level mark, and then install the reservoir
cap. NOTICE: 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 cooling system will not
be protected against frost and
corrosion. If water has been
added to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant as
soon as possible, otherwise the

shown.
Periodically check the throttle grip free
play and, if necessary, have a Yamaha
dealer adjust it.
EAU21403
Valve clearanceThe 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 pre-
vent this from occurring, have your
Yamaha dealer check and adjust the
valve clearance at regular intervals.TIPThis service must be performed whenthe engine is cold.
EAU64410
TiresTires 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 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

for this model.WARNING
EWA10512
Never overload your vehicle. Opera-
tion of an overloaded vehicle couldcause 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 complywith the local regulations.
WARNING
EWA10472
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 optimalcharacteristics.

12 Tire information
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
EWA10902
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 toavoid tire deflation during a ride.
After extensive tests, only the tires list-
ed below have been approved for this
model by Yamaha.
WARNING
EWA10601
This motorcycle is fitted with su-
per-high-speed tires. Note the fol-
lowing points in order to make the
most efficient use of these tires.
Use only the specified replace-
ment tires. Other tires may run
the danger of bursting at super
high speeds.
Brand-new tires can have a rela-
tively poor grip on certain road
surfaces until they have been
“broken in”. Therefore, it is ad-
visable before doing any
high-speed riding to ride con-
servatively for approximately
100 km (60 mi) after installing a
new tire.
The tires must be warmed up
before a high-speed run.
Always adjust the tire air pres-
sure according to the operatingconditions.
