Compression damping force
To increase the compression damping
force and thereby harden the compres-
sion damping, turn the adjusting screw
in direction
a. To decrease the com-
pression damping force and thereby
soften the compression damping, turn
the adjusting screw in direction
b.
CI-02E
NOTE:@ Although the total number of clicks of a
damping force adjusting mechanism
may not exactly match the above spec-
ifications due to small differences in
production, the actual number of clicks
always represents the entire adjusting
range. To obtain a precise adjustment,
it would be advisable to check the num-
ber of clicks of each damping force ad-
justing mechanism and to modify the
specifications as necessary. @

WARNING
@ This shock absorber contains high-
ly pressurized nitrogen gas. For
proper handling, read and under-
stand the following information be-
fore handling the shock absorber.
The manufacturer cannot be held re-
sponsible for property damage or
personal injury that may result from
improper handling.l
Do not tamper with or attempt to
open the gas cylinder.
l
Do not subject the shock ab-
sorber to an open flame or other
high heat sources, otherwise it
may explode due to excessive
gas pressure.
l
Do not deform or damage the
gas cylinder in any way, as this
will result in poor damping per-
formance.
l
Always have a Yamaha dealer
service the shock absorber.

4-PRE-OPERATION CHECKSThe condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or loss
of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual inspec-
tion, to check the following points before each ride.

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,
passenger, cargo, and accesso-
ries does not exceed the speci-
fied 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.
@
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. @1. Tire sidewall

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.
@Tire information
This motorcycle is equipped with cast
wheels and tubeless tires with valves.
EW000080
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.

NOTE:@ Using the alignment marks on each
side of the swingarm, make sure that
both chain pullers are in the same posi-
tion for proper wheel alignment. @
EC000096
CAUTION:@ Improper drive chain slack will over-
load the engine as well as other vital
parts of the motorcycle and can lead
to chain slippage or breakage. To
prevent this from occurring, keep
the drive chain slack within the
specified limits. @3. Tighten the locknuts, and then
tighten the axle nut to the specified
torque.
EAU03006
Lubricating the drive chain The drive chain must be cleaned and
lubricated at the intervals specified in
the periodic maintenance and lubrica-
tion chart, otherwise it will quickly wear
out, especially when riding in dusty or
wet areas. Service the drive chain as
follows.
EC000097
CAUTION:@ The drive chain must be lubricated
after washing the motorcycle or
riding in the rain. @1. Clean the drive chain with kero-
sene and a small soft brush.
ECA00053
CAUTION:@ To prevent damaging the O-rings,
do not clean the drive chain with
steam cleaners, high-pressure
washers or inappropriate solvents. @2. Wipe the drive chain dry.
3. Thoroughly lubricate the drive
chain with a special O-ring chain
lubricant.
ECA00052
CAUTION:@ Do not use engine oil or any other
lubricants for the drive chain, as
they may contain substances that
could damage the O-rings. @
