8 mm at the throttle grip. If the free play
is incorrect, ask a Yamaha dealer to
make this adjustment.

Valve clearance adjustmentThe correct valve clearance changes
with use, resulting in improper fuel/air
supply or engine noise. To prevent this,
the valve clearance must be adjusted
regularly. This adjustment however,
should be left to a professional
Yamaha service technician.

checked and adjusted when the
temperature of the tire equals the
ambient air temperature. Tire infla-

cording to total weight of cargo,
rider, passenger, and accessories
(fairing, saddlebags, etc. if approved
for this model), and vehicle speed. @

WARNING
@ Operating the motorcycle with ex-
cessively worn tires decrease riding
stability and can lead to loss of con-
trol. Have excessively worn tires re-
placed by a Yamaha dealer
immediately. Brakes, tires, and relat-
ed wheel parts replacement should
be left to a Yamaha Service Techni-
cian. @CE-26ENOTE:@ These limits may be different by regula-
tion from country to country. If so, con-
form to the limits specified by the
regulations of your own country. @Tire information
This motorcycle is equipped with tube-
less tires, tire valves and cast wheels.

WARNING
@ l
After extensive tests, the tires
mentioned below have been ap-
proved by Yamaha Motor Co.,
Ltd. for this model. No guaran-
tee for handling characteristics
can be given if tire combina-
tions other than what is ap-
proved are used on this
motorcycle. The front and rear
tires should be of the same
manufacture and design.
l
The use of tire valves and valve
cores other than listed below
could cause tire deflation dur-
ing extreme high speed riding.
Always use genuine parts or
their equivalent for replace-
ment.
l
Be sure to install the valve caps
securely, as these are important
to prevent air pressure leakage
during extreme high speed
riding.

WARNING
@ This motorcycle is fitted with super
high-speed running tires. The fol-
lowing points must be observed in
order for you to make fully effective
use of these tires.l
Never fail to use the specified
tires in tire replacement. Other
tires may have a danger of
bursting at super high-speeds.
l
New tires have a relatively low
grip on the road surface until
they have been slightly worn.
Therefore, approximately
100 km should be traveled at
normal speed before any high-
speed riding is done.
l
Before any high-speed runs, the
tires should be warmed-up suf-
ficiently.
l
Always inflate to the correct tire
pressure according to the oper-
ating conditions.

WheelsTo ensure maximum performance,
long service, and safe operation, note
the following:l
Always inspect the wheels before
a ride. Check for cracks, bends, or
warpage of the wheels. If any ab-
normal condition exists in a wheel,
consult a Yamaha dealer. Do not
attempt even small repairs to the
wheel. If a wheel is deformed or
cracked, it must be replaced.
l
Tires and wheels should be bal-
anced whenever either one is
changed or replaced. Failure to
have a wheel balanced can result
in poor performance, adverse han-
dling characteristics, and short-
ened tire life.
l
Ride at moderate speeds after
changing a tire since the tire sur-
face must first be broken in for it to
develop its optimal characteristics.
