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.
EAU21644
Tires Tires are the only contact between the
vehicle and the road. Safety in all con-
ditions of riding depends on a relatively
small area of road contact. Therefore, it
is essential to maintain the tires in good
condition at all times and replace them
at the appropriate time with the speci-
fied tires.
Tire air pressure
The tire air pressure should be checked
and, if necessary, adjusted before each
ride.
WARNING
EWA10503
Operation of this vehicle with im-
proper tire pressure may cause se-
vere injury or death from loss of
control.
The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the temperature
of the tires equals the ambient
temperature).

The tire air pressure must be ad-
justed in accordance with the
riding speed and with the totalweight of rider, passenger, car-
go, and accessories approved
for this model.WARNING
EWA10511
Never overload your vehicle. Opera-
tion of an overloaded vehicle couldcause an accident.Tire air pressure (measured on cold
tires):
0–90 kg (0–198 lb):Front:125 kPa (1.25 kgf/cm
2, 18 psi)
Rear: 175 kPa (1.75 kgf/cm2, 25 psi)
90–185 kg (198–408 lb):
Front:150 kPa (1.50 kgf/cm2, 22 psi)
Rear:
200 kPa (2.00 kgf/cm2, 29 psi)
Maximum load*: 185 kg (408 lb)
* Total weight of rider, passenger, car- go and accessories

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.
TIPThe tire tread depth limits may differ
from country to country. Always complywith the local regulations. Tire information
This motorcycle is equipped with tube
tires.
Tires age, even if they have not been
used or have only been used occasion-
ally. Cracking of the tread and sidewall
rubber, sometimes accompanied by
carcass deformation, is an evidence of
ageing. Old and aged tires shall be
checked by tire specialists to ascertain
their suitability for further use.
WARNING
EWA10461
The front and rear tires should be of
the same make and design, other-
wise the handling characteristics of
the vehicle may be different, whichcould lead to an accident.
After extensive tests, only the tires list-
ed below have been approved for this
model by Yamaha Motor Co., Ltd.
WARNING
EWA10571

Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the mo-
torcycle 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.

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

changing a tire since the tire
surface must first be “broken

Spoke wheels
WARNING
EWA10610
The wheels on this model are not de-
signed for use with tubeless tires.
Do not attempt to use tubeless tireson this model.
To maximize the performance, durabil-
ity, and safe operation of your motorcy-
cle, note the following points regarding
the specified wheels.
The wheel rims should be checked
for cracks, bends, warpage or oth-
er damage, and the spokes for
looseness or damage before each
ride. If any damage is found, have
a Yamaha dealer replace the
wheel. Do not attempt even the
smallest repair to the wheel. A de-
formed 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.
EAU48373
Adjusting the clutch lever free
play The clutch lever free play should mea-
sure 10.0–15.0 mm (0.39–0.59 in) as
shown. Periodically check the clutch le-
ver free play and, if necessary, adjust it
as follows.
1. Slide the rubber cover back at the clutch lever.
2. Loosen the locknut.
3. To increase the clutch lever free play, turn the clutch lever free play
adjusting bolt in direction (a). To
decrease the clutch lever free play,
turn the adjusting bolt in direction
(b).


After adjusting the brake lever
free play, check the free play
and make sure that the brake is
working properly.

A soft or spongy feeling in the
brake lever can indicate the
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.

Checking the shi
ft pedal The operation of the shift pedal should
be checked before each ride. If opera-
tion is not smooth, have a Yamaha
dealer check the vehicle.

Checking the brake fluid level Before riding, check that the brake fluid
is above the minimum level mark.
Check the brake fluid level with the top
of the reservoir level. Replenish the
brake fluid if necessary.
Front brakeRear brake
WARNING
EWA15990
Improper maintenance can result in
loss of braking ability. Observe
these precautions:
Insufficient brake fluid may al-
low air to enter the brake sys-
tem, reducing braking
performance.

Clean the filler cap before re-
moving. Use only DOT 4 brake
fluid from a sealed container.

Use only the specified brake flu-
id; otherwise, the rubber sealsmay deteriorate, causing leak-
age.

Refill with the same type of
brake fluid. Adding a brake fluid
other than DOT 4 may result in a
harmful chemical reaction.

Be careful that water does not
enter the brake fluid reservoir
when refilling. Water will signifi-
cantly lower the boiling point of
the fluid and may result in vaporlock.
NOTICE
ECA17640
Brake fluid may damage painted sur-
faces or plastic parts. Always cleanup spilled fluid immediately.
As the brake pads wear, it is normal for
the brake fluid level to gradually go
down. A low brake fluid level may indi-
cate worn brake pads and/or brake sys-
tem leakage; therefore, be sure to
check the brake pads for wear and the
brake system for leakage. If the brake
fluid level goes down suddenly, have a
Yamaha dealer check the cause before
further riding.

Checking and lubr
icating the
cables The operation of all control cables and
the condition of the cables should be
checked before each ride, and the ca-
bles and cable ends should be lubricat-
ed if necessary. If a cable is damaged
or does not move smoothly, have a
Yamaha dealer check or replace it.
WARNING! Damage to the outer
housing of cables may result in in-
ternal rusting and cause interfer-
ence with cable movement. Replace
damaged cables as soon as possi-
ble to prevent unsafe condi-
tions.
[EWA10711]

EAU23114
Checking and lubricating the
throttle grip and cable The operation of the throttle grip should
be checked before each ride. In addi-
tion, the cable should be lubricated by a
Yamaha dealer at the intervals speci-
fied in the periodic maintenance chart.
The throttle cable is equipped with a
rubber cover. Make sure that the cover
is securely installed. Even though the
cover is installed correctly, it does not
completely protect the cable from water
entry. Therefore, use care not to pour
water directly onto the cover or cable
when washing the vehicle. If the cable
or cover becomes dirty, wipe clean with
a moist cloth.
Recommended lubricant: Yamaha Chain and Cable Lube or
engine oil

Checking and lubricating the
sidestand The operation of the sidestand should
be checked before each ride, and the
sidestand pivot and metal-to-metal
contact surfaces should be lubricated if
necessary.
WARNING
EWA10731
If the sidestand does not move up
and down smoothly, have a Yamaha
dealer check or repair it. Otherwise,
the sidestand could contact the
ground and distract the operator, re-sulting in a possible loss of control.

Lubricating the swingarm
pivots The swingarm pivots must be lubricat-
ed by a Yamaha dealer at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU23272
Checking the front fork The condition and operation of the front
fork must be checked as follows at the
intervals specified in the periodic main-
tenance and lubrication chart.
To check the condition
Check the inner tubes for scratches,
damage and excessive oil leakage.
To check the operation1. Place the vehicle on a level sur- face and hold it in an upright posi-
tion. WARNING! To avoid injury,
securely support the vehicle so
there is no danger of it falling
over.
[EWA10751]

2. While applying the front brake, push down hard on the handlebars
several times to check if the front
fork compresses and rebounds
smoothly.
