CAUTION:@ Do not use any type of tools to re-
move or install the cap as the igni-
tion coil coupler may get damaged.
The spark plug cap may be difficult
to remove because a rubber seal on
the end of the cap is tightly fit into
the cylinder bore. To remove the
cap, simply twist it back and forth
while pulling it upward; when install-
ing the cap, twist it back and forth
while pushing it downward. @

Engine oilOil level inspection
1. Place the motorcycle on a level
place and hold it in an upright posi-
tion. Warm up the engine for sev-
eral minutes.NOTE:@ Be sure the motorcycle is positioned
straight up when checking the oil level.
A slight tilt toward the side can result in
false readings. @
2. Stop the engine and remove the
dipstick.NOTE:@ Wait a few minutes until the oil level
settles before checking. @3. The oil level should be between
maximum and minimum marks on
the dipstick. If the level is low, fill
the engine with sufficient oil to
reach the specified level.

several minutes. While warming
up, check for oil leakage. If oil
leakage is found, stop the engine
immediately and check for the
cause.

Drive chain slack adjustment1. Loosen the axle nut.
2. Loosen the locknuts on each side.
To tighten the chain, turn the chain
adjusting bolts in direction
a. To
loosen the chain, turn the adjust-
ing bolts in direction
b and push
the wheel forward. Turn each ad-
justing bolt exactly the same
amount to maintain correct axle
alignment. There are marks on
each 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.
EAU03006
Drive chain lubricationThe 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 washers, and sol-
vents can damage the drive 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. @

Cable inspection and
lubrication
EW000112
WARNING
@ Damage to the outer housing of ca-
bles may lead to internal rusting and
interfere with the cable movement.
Replace damaged cables as soon as
possible to prevent unsafe condi-
tions. @Lubricate the cables and cable ends. If
a cable does not operate smoothly, ask
a Yamaha dealer to replace it.
EAU00773
Throttle cable and grip
lubricationThe throttle twist grip assembly should
be greased at the time that the cable is
lubricated, since the grip must be re-
moved to get at the end of the throttle
cable. After removing the screws, hold
the end of the cable up in the air and
put in several drops of lubricant. With
the throttle grip disassembled, coat the
metal surface of the grip assembly with
a suitable all-purpose grease.

Front fork inspectionVisual check
EW000115
WARNING
@ 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 inspectionPeriodically 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.
