Valve clearance
The valves are an important engine
component, and since valve clearance
changes with use, they must be
checked and adjusted at the intervals
specified in the periodic maintenance
chart. Unadjusted valves can result in
improper air-fuel mixture, engine
noise, and eventually engine damage.
To prevent this from occurring, have
your Yamaha dealer check and adjust
the valve clearance at regular intervals.
TIP
This service must be performed when
the engine is cold.
EAU64410
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
EWA10504
Operation of this vehicle with im-
proper tire pressure may cause se-
vere injury or d eath from loss of
control.  The tire air pressure must b e
checked and a djuste d on col d
tires (i.e., when the temperature
of the tires equals the am bient
temperature).
 The tire air pressure must b e
a d juste d in accor dance with the
ri din g speed and with the total
wei ght of ri der, passen ger, car-
g o, an d accessories approve d
for this mo del.

Cast wheels
To maximize the performance, durabil-
ity, and safe operation of your vehicle,
note the following points regarding the
specified wheels.
 The wheel rims should be
checked for cracks, bends, warp-
age or other 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.

YCC-S clutch
This model is equipped with a hydrau-
lic clutch, therefore, it is necessary to
check the YCC-S clutch fluid level and
check the hydraulic system for leak-
age. (See page 6-25.)
TIP
If shifting becomes rough or clutch
slippage occurs, or if you notice poor
acceleration or engine stalls, have a
Yamaha dealer check the clutch for wear.

Checkin g the front an d rear
b rake pa ds
The front and rear brake pads must be
checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart.
EAU43432Front brake pa ds
The front brake calipers are equipped
with two sets of brake pads.
Each front brake pad is provided with a
wear indicator groove, which allows
you to check the brake pad wear with-
out having to disassemble the brake.
To check a brake pad for wear, check
its wear indicator groove. If a brake
pad has worn to the point that the wear
indicator groove has almost disap-
peared, have a Yamaha dealer replace
the brake pads as a set.
EAU22501Rear brake pa ds

other than DOT 4 may result in a
harmful chemical reaction.
 Be careful that water or dust
d oes not enter the brake or
YCC-S clutch flui d reservoir
when refillin g. Water will si gnifi-
cantly lower the boilin g point of

NOTICE
ECA17641
Brake flui d may damag e painte d
surfaces or plastic parts. Always
clean up spille d flui d imme diately.
The brake and YCC-S clutch fluid res-
ervoir diaphragms will lose their shape
from the negative pressure if the fluid
level goes down too far. Be sure to re-
turn the diaphragms to their original
shape before reinstalling them.
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
system leakage; therefore, be sure to
check the brake pads for wear and the
brake system for leakage. A low
YCC-S clutch fluid level may indicate
YCC-S clutch system leakage; there-
fore, be sure to check the YCC-S
clutch system for leakage. If the brake
or YCC-S clutch fluid level goes down
suddenly, have a Yamaha dealer check
the cause before further riding.
EAU40604
Chan gin g the brake an d
YCC-S clutch flui ds
Have a Yamaha dealer change the
brake and YCC-S clutch fluids at the
intervals specified in the periodic main-
tenance and lubrication chart. In addi-
tion, have the oil seals of the brake and
YCC-S clutch master cylinders and
calipers as well as the brake and
YCC-S clutch hoses replaced at the in-
tervals listed below or whenever they
are damaged or leaking.
 Oil seals: Replace every two
years.
 Brake and YCC-S clutch hoses:
Replace every four years.

throttle grip an d ca ble
The operation of the throttle grip
should be checked before each ride. In
addition, the cable should be lubricat-
ed by a Yamaha dealer at the intervals
specified 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 wa-
ter 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.
