Adjusting the throttle cable
free play The throttle cable free play should
measure 3–7 mm at the throttle grip.
Periodically check the throttle cable
free play and, if necessary, have a
Yamaha dealer adjust it.
EAU00637
Adjusting the valve clearance The valve clearance changes with use,
resulting in improper air-fuel mixture
and/or engine noise. To prevent this
from occurring, the valve clearance
must be adjusted by a Yamaha dealer
at the intervals specified in the periodic
maintenance and lubrication chart.
EAU00658
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
_ l
The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the temperature
of the tires equals the ambient
temperature).
l
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.

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. l
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.
l
Do not carry along loosely
packed items, which can shift
during a ride.
l
Securely pack the heaviest
items close to the center of the
motorcycle and distribute the
weight evenly on both sides.
l
Adjust the suspension and tire
air pressure with regard to the
load.
l
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. _
EW000079
WARNING
_ l
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.
l
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
_ l
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.
l
After extensive tests, only the
tires listed below have been ap-
proved for this model by
Yamaha Motor Co., Ltd.
l
Always make sure that the valve
caps are securely installed to
prevent air pressure leakage.
l
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.l
Use only the specified replace-
ment tires. Other tires may run
the danger of bursting at super
high speeds.
l
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.
l
The tires must be warmed up
before a high-speed run.
l
Always adjust the tire air pres-
sure according to the operating
conditions.

MOTORCYCLE CARE AND STORAGE
7-3
7After cleaning
1. Dry the motorcycle with a chamois
or an absorbing cloth.
2. Immediately dry the drive chain
and lubricate it to prevent it from
rusting.
3. Use a chrome polish to shine
chrome, aluminum and stainless-
steel parts, including the exhaust
system. (Even the thermally in-
duced discoloring of stainless-
steel exhaust systems can be re-
moved through polishing.)
4. To prevent corrosion, it is recom-
mended to apply a corrosion pro-
tection spray on all metal,
including chrome- and nickel-plat-
ed, surfaces.
5. Use spray oil as a universal clean-
er to remove any remaining dirt.
6. Touch up minor paint damage
caused by stones, etc.
7. Wax all painted surfaces.
8. Let the motorcycle dry completely
before storing or covering it.
EWA00001
WARNING
_ l
Make sure that there is no oil or
wax on the brakes or tires. If
necessary, clean the brake
discs and brake linings with a
regular brake disc cleaner or ac-
etone, and wash the tires with
warm water and a mild deter-
gent.
l
Before operating the motor-
cycle test its braking perfor-
mance and cornering behavior.
_
ECA00013
CAUTION:_ l
Apply spray oil and wax spar-
ingly and make sure to wipe off
any excess.
l
Never apply oil or wax to any
rubber and plastic parts, but
treat them with a suitable care
product.
l
Avoid using abrasive polishing
compounds as they will wear
away the paint.
_NOTE:_ Consult a Yamaha dealer for advice on
what products to use. _

76. Lubricate all control cables and
the pivoting points of all levers and
pedals as well as of the sidestand/
centerstand.
7. Check and, if necessary, correct
the tire air pressure, and then lift
the motorcycle so that both of its
wheels are off the ground. Alterna-
tively, turn the wheels a little every
month in order to prevent the tires
from becoming degraded in one
spot.
8. Cover the muffler outlet with a
plastic bag to prevent moisture
from entering it.
9. Remove the battery and fully
charge it. Store it in a cool, dry
place and charge it once a month.
Do not store the battery in an ex-
cessively cold or warm place [less
than 0 °C or more than 30 °C]. For
more information on storing the
battery, see page 6-31.
NOTE:_ Make any necessary repairs before
storing the motorcycle. _
