Engine oil and oil filter
element The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter ele-
ment replaced at the intervals specified
in the periodic maintenance and lubri-
cation chart.
To check the engine oil level
1. Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:_ Make sure that the motorcycle is posi-
tioned straight up when checking the oil
level. A slight tilt to the side can result in
a false reading. _2. Start the engine, warm it up for
15 minutes, and then turn it off.3. Wait a few minutes until the oil set-
tles, remove the oil filler cap, wipe
the dipstick clean, insert it back
into the oil filler hole (without
screwing it in and with the arrow
mark pointing upward as shown),
and then remove it again to check
the oil level.
NOTE:_ The engine oil should be between the
minimum and maximum level marks. _
EC000000
CAUTION:_ Do not operate the motorcycle until
you know that the engine oil level is
sufficient. _
EW000065
WARNING
_ Never remove the engine oil tank
cap after high-speed operation, oth-
erwise hot engine oil could spout
out and cause damage or injury. Al-
ways let the engine oil cool down
sufficiently before removing the oil
tank cap. _

CAUTION:_
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 of
the coolant will be reduced.

WARNING
_ Never attempt to remove the radia-
tor cap when the engine is hot. _
NOTE:_
The radiator fan is automatically
switched on or off according to the
coolant temperature in the radia-
tor.
If the engine overheats, see page
6-44 for further instructions.

EAU04461
To change the coolant
1. Place the motorcycle on a level
surface and let the engine cool if
necessary.
2. Remove the seat. (See page 3-11
for seat removal and installation
procedures.)
3. Remove cowling B and panel B.
(See pages 6-5 and 6-6 for cowl-
ing and panel removal and instal-
lation procedures.)
4. Remove the fuel tank bolts, and
then lift the fuel tank to position it
away from the coolant reservoir.
(Do not disconnect the fuel hos-
es!)
5. Place a container under the en-
gine to collect the used coolant.

WARNING
_
Before installing the fuel tank,
make sure that the fuel hoses
are not damaged. If any fuel
hose is damaged, do not start
the engine but have a Yamaha
dealer replace the hose, other-
wise fuel may leak.
Make sure that the fuel hoses
are properly connected and
routed, and not pinched.
Be sure to place the fuel tank
breather hose in the original po-
sition.
_19. Install the panel, the cowling, and
the seat.
20. Start the engine, and then check
the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system.

for seat removal and installation
procedures.)
2. Remove cowlings A and B as well
as panels A and B. (See pages 6-5
and 6-6 for cowling and panel re-
moval and installation proce-
dures.)3. Remove the fuel tank bolts, and
then lift the fuel tank away from the

CAUTION:_
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
pistons and/or cylinders may
become excessively worn.

Adjusting the engine idling
speed The engine idling speed must be
checked and, if necessary, adjusted as
follows at the intervals specified in the
periodic maintenance and lubrication
chart.
1. Start the engine and warm it up for
several minutes at 1,000–
2,000 r/min while occasionally rev-
ving it to 4,000–5,000 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.
EW000082
WARNING
_
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
adjusted in accordance with the
riding speed and with the total
weight of rider, passenger, car-
go, and accessories approved
for this model.

CE-01E
CE-07EEWA00012
WARNING
_ Because loading has an enormous
impact on the handling, braking, per-
formance and safety characteristics
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, pas-
senger, cargo, and accessories
does not exceed the specified
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 air
pressure before each ride.

6 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.
CE-08ENOTE:_ The tire tread depth limits may differ
from country to country. Always comply
with the local regulations. _
EW000079
WARNING
_
Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the
motorcycle with excessively
worn tires decreases riding sta-
bility 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.

WARNING
_
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 a
high-speed ride.

WARNING
@ 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.
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 conserva-
tively for approximately 100 km
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 operating
conditions.
