EAU00373
WARNING
_

Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer re-
garding any control or function
that you do not thoroughly
understand.


Never start the engine or operate
it in a closed area for any length
of time. Exhaust fumes are poi-
sonous, and inhaling them can
cause loss of consciousness
and death within a short time. Al-
ways make sure that there is ad-
equate ventilation.


Before starting out, make sure
that the sidestand is up. If the
sidestand is not raised com-
pletely, it could contact the
ground and distract the opera-
tor, resulting in a possible loss
of control.

brication will keep your vehicle in the
safest and most efficient condition pos-
sible. The most important points of in-
spection, adjustment, and lubrication
are explained on the following pages.
The intervals given in the periodic main-
tenance and lubrication chart should be
simply considered as a general guide
under normal riding conditions. Howev-
er, DEPENDING ON THE WEATHER,
TERRAIN, GEOGRAPHICAL LOCA-
TION, AND INDIVIDUAL USE, THE
MAINTENANCE INTERVALS MAY
NEED TO BE SHORTENED.

WARNING
_ 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 air
pressure before each ride.

6Tire 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. _
Tire information
This motorcycle is equipped with tube
tires.
EW000078
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.
_CE-10EEAU00681
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.


It is not recommended to patch
a punctured tube. If unavoid-
able, however, patch the tube
very carefully and replace it as
soon as possible with a high-
quality product.

WARNING
_

After adjusting the brake lever
free play, check the free play

presence of air in the hydraulic
system. If there is air in the hy-
draulic system, have a Yamaha
dealer bleed the system before
operating the motorcycle. Air in
the hydraulic system will dimin-
ish the braking performance,
which may result in loss of con-
trol and an accident.
