6To install a spark plug
1. Measure the spark plug gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifica-
tion.
2. Clean the surface of the spark
plug gasket and its mating sur-
face, and then wipe off any grime
from the spark plug threads.3. Install the spark plug with the
spark plug wrench, and then tight-
en it to the specified torque.
NOTE:_ If a torque wrench is not available when
installing a spark plug, a good estimate
of the correct torque is 1/4–1/2 turn
past finger tight. However, the spark
plug should be tightened to the speci-
fied torque as soon as possible. _4. Install the spark plug cap.

Engine oil and oil filter
element The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter ele-
ment replaced at the intervals specified
in the periodic maintenance and lubri-
cation chart.
To check the engine oil level
1. Place the motorcycle on the cen-
terstand.NOTE:_ Make sure that the motorcycle is posi-
tioned straight up when checking the oil
level. A slight tilt to the side can result in
a false reading. _2. Start the engine, warm it up for
several minutes, and then turn it
off.

0.8–0.9 mm

CAUTION:_
In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a
higher quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.
Make sure that no foreign mate-
rial enters the crankcase.
_
11. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off
and check for the cause.NOTE:_ After the engine is started, the engine
oil level warning light should go off if the
oil level is sufficient. _
EC000067
CAUTION:_ If the oil level warning light flickers
or remains on, immediately turn the
engine off and have a Yamaha deal-
er check the vehicle. _12. Turn the engine off, and then
check the oil level and correct it if
necessary. Recommended engine oil:
See page 8-1.
Oil quantity:
Without oil filter element replace-
ment:
3.0 L
With oil filter element replace-
ment:
3.35 L
Total amount (dry engine):

CAUTION:_ Do not use engine oil or any other
lubricants for the drive chain, as
they may contain substances that
could damage the O-rings. _
EAU02962
Checking and lubricating the
cables The operation of all control cables and
the condition of the cables should be
checked before each ride, and the ca-
bles and cable ends should be lubricat-
ed if necessary. If a cable is damaged
or does not move smoothly, have a
Yamaha dealer check or replace it.
EW000112
WARNING
_ Damage to the outer sheath may in-
terfere with proper cable operation
and will cause the inner cable to
rust. Replace a damaged cable as
soon as possible to prevent unsafe
conditions. _
EAU04034
Checking and lubricating the
throttle grip and cable The operation of the throttle grip should
be checked before each ride. In addi-
tion, the cable should be lubricated or
replaced at the intervals specified in
the periodic maintenance chart.
Recommended lubricant:
Engine oil

Checking the front fork The condition and operation of the front
fork must be checked as follows at the
intervals specified in the periodic main-
tenance and lubrication chart.
To check the condition
EW000115
WARNING
_ Securely support the motorcycle so
that there is no danger of it falling
over. _Check the inner tubes for scratches,
damage and excessive oil leakage.To check the operation
1. Place the motorcycle on a level
surface and hold it in an upright
position.
2. While applying the front brake,
push down hard on the handle-
bars several times to check if the
front fork compresses and re-
bounds smoothly.
EC000098
CAUTION:_ If any damage is found or the front
fork does not operate smoothly,
have a Yamaha dealer check or re-
pair it. _
Recommended lubricant:
Lithium-soap-based grease
(all-purpose grease)
