4. Install the final gear oil drain bolt
and its new gasket, and then tight-
en the bolt to the specified torque.
5. Refill with the recommended final gear oil to the brim of the filler
hole.
6. Check the oil filler bolt gasket for damage, and replace it if neces-
sary.
7. Install the oil filler bolt and its gas- ket, and then tighten the bolt to
the specified torque.
8. Check the final gear case for oil leakage. If oil is leaking, check for
the cause.

Coolant
The coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU54163To check the coolant level1. Place the vehicle on the center- stand.
TIP
The coolant level must be
checked on a cold engine since
the level varies with engine tem-
perature.
Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.
2. Remove the left cowling vent pan-
el. (See page 3-41.)
3. Check the coolant level in the coolant reservoir.
TIP
The coolant should be between the
minimum and maximum level marks.

Remove only the coolant reser-
voir cap. Never attempt to re-
move the ra diator cap when the

5. Add coolant or distilled water to
raise the coolant to the maximum
level mark, and install the coolant
reservoir cap. NOTICE: If coolant

not use har d water or salt water
since it is harmful to the en gine.
If water has been used instead
of coolant, replace it with cool-
ant as soon as possi ble, other-
wise the coolin g system will not

Valve clearance
The valve clearance changes with use,
resulting in improper air-fuel mixture

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 be
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 be
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.
WARNING
EWA10512
Never overloa d your vehicle. Opera-
tion of an overloa ded vehicle coul d
cause an acci dent.
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.
Tire air pressure (measure d on col d

Tire information This model is equipped with tubeless
tires and tire air valves.
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.

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 leakage
before each ride. If the YCC-S clutch
plates wear out, shifting becomes
rough or clutch slippage will occur,
causing poor acceleration. If any of the
above occurs, have a Yamaha dealer
check the YCC-S clutch.

Checkin g the brake lever free
play
There should be no free play at the
brake lever end. If there is free play,
have a Yamaha dealer inspect the
brake system.
WARNING
EWA14212
A soft or spon gy feelin g in the b rake
lever can in dicate the presence of
air in the hy draulic system. If there is
air in the hy draulic system, have a
Yamaha dealer blee d the system be-
fore operatin g the vehicle. Air in the
hy draulic system will diminish the
b rakin g performance, which may re-
sult in loss of control an d an acci-
d ent.
