Owners are personally responsible for their vehicleÕs condition. Your motorcycleÕs vital functions can start to deteriorate
quickly and unexpectedly, even if it remains unused (for instance, if it is exposed to the elements). Any damage, fluid leak or
loss of tire pressure could have serious consequences. Therefore, it is very important that, in addition to a thorough visual in-
spection, you check the following points before each ride.

EAU00683
Operating the motorcycle with ex-
cessively worn tires decrease riding
stability and can lead to loss of con-
trol. Have excessively worn tires re-
placed by a Yamaha dealer
immediately. Brakes, tires, and re-
lated wheel parts replacement
should be left to a Yamaha Service
Technician.
EAU00687
Wheels
To ensure maximum performance,
long service, and safe operation, note
the following:
lAlways inspect the wheels before
a ride. Check for cracks, bends, or
warpage of the wheels. If any ab-
normal condition exists in a wheel,
consult a Yamaha dealer. Do not
attempt even small repairs to the
wheel. If a wheel is deformed or
cracked, it must be replaced.
lTires and wheels should be bal-
anced whenever either one is
changed or replaced. Failure to
have a wheel balanced can result
in poor performance, adverse han-
dling characteristics, and short-
ened tire life.
lRide at moderate speeds after
changing a tire since the tire sur-
face must first be broken in for it to
develop its optimal characteristics.
1. Locknut
2. Adjusting bolt
c. Free play
EAU00694
Clutch lever free play
adjustment
The clutch lever free play should be ad-
justed to 2 ~ 3 mm.
1. Loosen the locknut at the clutch le-
ver.
2. Turn the adjusting bolt at the
clutch lever in direction a
to in-
crease free play or in direction b
to decrease free play.
3. Tighten the locknut at the clutch
lever.

Brake fluid replacement
The brake fluid should be replaced only
by trained Yamaha service personnel.
Have the Yamaha dealer replace the
following components during periodic
maintenance or when they are dam-
aged or leaking:
loil seals (every two years)
lbrake hoses (every four years)a. Chain slack
EAU00745
Drive chain slack check
NOTE:
Spin the wheel several times and find
the tightest position of the chain. Check
and/or adjust the chain slack while itÕs
in this tightest position.
Inspect the drive chain when the motor-
cycle is on the centerstand. Check the
slack at the position shown in the illus-
tration. Normal slack is approximately
30 ~ 40 mm. If the slack exceeds
40 mm, adjust.

Drive chain slack adjustment
1. Loosen the axle nut.
2. Loosen the locknuts on each side.
To tighten the chain, turn the chain
adjusting nuts in direction a
. To
loosen the chain, turn the adjust-
ing nuts in direction b
and push
the wheel forward. Turn each ad-
justing nut exactly the same
amount to maintain correct axle
alignment. There are marks oneach side of the swingarm. Use
these marks to align the rear
wheel.
EC000096
CAUTION:
Too little chain slack will overload
the engine and other vital parts.
Keep the slack within the specified
limits.
3. After adjusting, tighten the lock-
nuts. Then tighten the axle nut to
the specified torque.
Tightening torque:
Axle nut:
105 Nm (10.5 mákg)
EAU00769
Drive chain lubrication
The chain consists of many parts which
work with each other. If the chain is not
maintained properly, it will wear out
quickly. Therefore, the chain must be
serviced regularly. This service is es-
pecially necessary when riding in dusty
areas. This motorcycle is equipped
with a sealed type chain. Steam clean-
ing, high-pressure washes, and sol-
vents can damage chain so do not use
these for cleaning it. Use only kerosene
to clean the drive chain. Wipe it dry,
and thoroughly lubricate it with SAE 30
~ 50W motor oil. Do not use any other
lubricants on the drive chain. They may
contain solvents that could damage the
sealed chain.
EC000097
CAUTION:
Be sure to oil the chain after wash-
ing the motorcycle or riding in the
rain.

Front fork inspection
Visual checkEW000115
Securely support the motorcycle so
there is no danger of it falling over.
Check for scratches or damage on the
inner tube and excessive oil leakage
from the front fork.
Operation check
1. Place the motorcycle on a level
place.
2. Hold the motorcycle in an upright
position and apply the front brake.
3. Push down hard on the handle-
bars several times and check if the
fork rebounds smoothly.
EC000098
CAUTION:
If any damage or unsmooth move-
ment is found with the front fork,
consult a Yamaha dealer.
EAU00794
Steering inspection
Periodically inspect the condition of the
steering. Worn out or loose steering
bearings may be dangerous. Place a
stand under the engine to raise the
front wheel off the ground. Hold the
lower end of the front forks and try to
move them forward and backward. If
any free play can be felt, ask a Yamaha
dealer to inspect and adjust the steer-
ing. Inspection is easier if the front
wheel is removed.

Wheel bearings
If there is play in the front or rear wheel
hub or if the wheel does not turn
smoothly, have a Yamaha dealer in-
spect the wheel bearings.
EAU00800
Battery
This motorcycle is equipped with a
sealed-type battery. Therefore it is not
necessary to check the electrolyte or fill
the battery with distilled water.
lIf the battery seems to have dis-
charged, consult a Yamaha deal-
er.
lIf the motorcycle is equipped with
optional electrical accessories, the
battery tends to discharge more
quickly, so be sure to recharge it
periodically.
EC000101
CAUTION:
Never try to remove the sealing caps
of the battery cells. The battery will
be damaged.
EW000116
Battery electrolyte is poisonous and
dangerous, causing severe burns,
etc. It contains sulfuric acid. Avoid
contact with skin, eyes or clothing.
ANTIDOTE:
lEXTERNAL: Flush with water.
lINTERNAL: Drink large quanti-
ties of water or milk. Follow with
milk of magnesia, beaten egg,
or vegetable oil. Call a physi-
cian immediately.
lEYES: Flush with water for
15 minutes and get prompt
medical attention.
Batteries produce explosive gases.
Keep sparks, flame, cigarettes etc.,
away. Ventilate when charging or
using in an enclosed space. Always
shield your eyes when working near
batteries. KEEP OUT OF REACH OF
CHILDREN.
