Checking the throttle cable
free play
1. Throttle cable free play
The throttle cable free play should
measure 3.0–5.0 mm (0.12–0.20 in) at
the throttle grip. Periodically check
the throttle cable free play and, if
necessary, have a Yamaha dealer
adjust it.
EAU21401
Valve clearance
The valve clearance changes with
use, resulting in improper air-fuel mix-
ture and/or engine noise. To prevent
this from occurring, the valve clearan-
ce must be adjusted by a Yamaha
dealer at the intervals specified in the
periodic maintenance and lubrication
chart.
EAU21873
Tires
To maximize the performance, durabi-
lity, and safe operation of your vehi-
cle, note the following points regar-
ding the specified tires.
Tire air pressure
The tire air pressure should be chec-
ked and, if necessary, adjusted befo-
re each ride.
EWA10501
Operation of this vehicle with
improper tire pressure may cause
severe injury or death from loss of
control.
The tire air pressure must be
checked and adjusted on cold

tires (i.e., when the temperatu-
re of the tires equals the
ambient temperature).
The tire air pressure must be
adjusted in accordance with
the riding speed and with the
total weight of rider, passenger,
cargo, and accessories appro-
ved for this model.
EWA10511
Never overload your vehicle. Ope-
ration of an overloaded vehicle
could cause an accident.
Tire inspection
1. Tire tread depth
2. Tire sidewall
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 Yama-
ha dealer replace the tire immediately.
TIP
The tire tread depth limits may differ
from country to country. Always
comply with the local regulations.

EWA10470
Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the
vehicle with excessively worn
tires decreases riding stability
and can lead to loss of control.
The replacement of all wheel
and brake related parts, inclu-
ding the tires, should be left to
a Yamaha dealer, who has the
necessary professional know-
ledge and experience.
EAU21960
Cast wheels
To maximize the performance, durabi-
lity, and safe operation of your vehi-
cle, note the following points regar-
ding the specified wheels.
The wheel rims should be chec-
ked for cracks, bends or warpage
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 deformed or crac-
ked 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
handling characteristics, and a
shortened tire life.
Ride at moderate speeds after
changing a tire since the tire sur-
face must first be “broken in” for
it to develop its optimal characte-
ristics.

lever free play and, if necessary, have
a Yamaha dealer check the brake sys-
tem.
EWA10641
An incorrect brake lever free play
indicates a hazardous condition in
the brake system. Do not operate
the vehicle until the brake system
has been checked or repaired by a
Yamaha dealer.
EAU22390
Checking the front and rear
brake pads
The front and rear brake pads must
be checked for wear at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU22430
Front brake pads
1. Wear indicator groove
Each front brake pad is provided with
wear indicator grooves, which allow
you to check the brake pad wear wit-
hout having to disassemble the brake.
To check the brake pad wear, check
the wear indicator grooves. If a brake
pad has worn to the point that the
wear indicator grooves have almostdisappeared, have a Yamaha dealer
replace the brake pads as a set.
EAU22520
Rear brake pads
1. Wear indicator groove
The rear brake is provided with a
check plug, which, if it is removed,
allows you to check the brake pad
wear without disassembling the bra-
ke. To check the brake pad wear,
check the position of the wear indica-
tor while applying the brake. If a bra-
ke pad has worn to the point that the
wear indicator almost touches the
brake disc, have a Yamaha dealer
replace the brake pads as a set.

EAU22580
Checking the brake fluid
level
Front brake
1. Minimum level mark
Rear brake
1. Minimum level mark
Insufficient brake fluid may allow air
to enter the brake system, possibly
causing it to become ineffective.
Before riding, check that the brake
fluid is above the minimum level mark
and replenish if necessary. A low bra-
ke fluid level may indicate worn brake
pads and/or brake system leakage. If
the brake fluid level is low, be sure to
check the brake pads for wear and
the brake system for leakage.
Observe these precautions:
When checking the fluid level,
make sure that the top of the bra-
ke fluid reservoir is level.
Use only the recommended qua-
lity brake fluid, otherwise the rub-
ber seals may deteriorate, cau-
sing leakage and poor braking
performance.
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performan-
ce.
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 vapor
lock.
Brake fluid may deteriorate pain-
ted surfaces or plastic parts.
Always clean up spilled fluid
immediately.
As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if
the brake fluid level goes down
suddenly, have a Yamaha dealer
check the cause.
Recommended brake fluid:DOT 4

Changing the brake fluid
Have a Yamaha dealer change the
brake fluid at the intervals specified in
the TIP after the periodic maintenan-
ce and lubrication chart. In addition,
have the oil seals of the master cylin-
ders and calipers as well as the brake
hoses replaced at the intervals listed
below or whenever they are damaged
or leaking.
Oil seals: Replace every two
years.
Brake hoses: Replace every four
years.

Checking and lubricating the
throttle grip and cable
The operation of the throttle grip
should be checked before each ride.
In addition, the cable should be lubri-
cated at the intervals specified in the
periodic maintenance chart.

1. Centerstand
The operation of the centerstand and
sidestand should be checked before
each ride, and the pivots and metal-to-metal contact surfaces should be
lubricated if necessary.
EWA10741
If the centerstand or sidestand
does not move up and down smo-
othly, have a Yamaha dealer check
or repair it. Otherwise, the centers-
tand or sidestand could contact the
ground and distract the operator,
resulting in a possible loss of con-
trol.

Checking the front fork
The condition and operation of the
front fork must be checked as follows
at the intervals specified in the perio-
dic maintenance 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 surfa- ce 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 handle-
bars several times to check if the
front fork compresses and
rebounds smoothly.
ECA10590
If any damage is found or the front
fork does not operate smoothly,
have a Yamaha dealer check or
repair it.
EAU45511
Checking the steering
Worn or loose steering bearings may
cause danger. Therefore, the opera-
tion of the steering must be checked
as follows at the intervals specified in
the periodic maintenance and lubrica-
tion chart.1. Place the vehicle on the centers- tand. WARNING! To avoid
injury, securely support the
vehicle so there is no danger of
it falling over.
[EWA10751]
2. Hold the lower ends of the front fork legs and try to move them
forward and backward. If any free
play can be felt, have a Yamaha
dealer check or repair the stee-
ring.
