CAUTION:

ECA11620

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.
9. 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.
10. Turn the engine off, and then
check the oil level and correct it if
necessary.
EAU20070
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.
EAU20101
To check the coolant level
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 the
side can result in a false reading.
2. Check the coolant level in the cool-
ant reservoir.
NOTE:

The coolant should be between the
minimum and maximum level marks. Recommended engine oil:
See page 8-1.
Oil quantity:
Without oil filter element replace-
ment:
3.80 L (4.02 US qt)
(3.34 Imp.qt)
With oil filter element replace-
ment:
3.90 L (4.12 US qt)
(3.43 Imp.qt)

3. If the coolant is at or below the
minimum level mark, remove pan-
el B (See page 6-5.), remove the
reservoir cap, add coolant to the
maximum level mark, and then in-
stall the reservoir cap and the pan-
el.
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 of
the coolant will be reduced.
WARNING

WARNING

EWA11020
Because loading has an enormous
impact on the handling, braking,
performance and safety characteris-
tics of your motorcycle, you shouldkeep the following precautions in
mind.

NEVER OVERLOAD THE MO-
TORCYCLE! 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 air
pressure 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 comply

with 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 information
This motorcycle is equipped with cast
wheels and tubeless tires with valves.
WARNING

EWA10900

The front and rear tires should
be of the same make and de-
sign, otherwise the handling
characteristics of the motorcy-
cle cannot be guaranteed.

After extensive tests, only the
tires listed below have been ap-
proved for this model by Yama-
ha Motor Co., Ltd.

Always make sure that the valvecaps are securely installed to
prevent air pressure leakage.

Use only the tire valves and
valve cores listed below to
avoid tire deflation during a ride.

WARNING

EWA10600
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 operating
conditions.
EAU21960
Cast wheels
To maximize the performance, durabil-
ity, and safe operation of your vehicle,
note the following points regarding the
specified wheels.

The wheel rims should be checked
for cracks, bends or warpage be-
fore each ride. If any damage is
found, have a Yamaha dealer re-
place the wheel. Do not attempt
even the smallest repair to the
wheel. A deformed or cracked
wheel must be replaced.

The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced. An
unbalanced wheel can result in
poor performance, adverse han-
dling characteristics, and a short-
ened tire life.

Ride at moderate speeds after
changing a tire since the tire sur-
face must first be “broken in” for it
to develop its optimal characteris-
tics.
