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.
5. Place the spark plug cover in the
original position.

Engine oil 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 vehicle on a level sur-
face and hold it in an upright posi-
tion.NOTE:Make sure that the vehicle is positioned
straight up when checking the oil level.
A slight tilt to the side can result in afalse reading.
2. Start the engine, warm it up for
several minutes, and then turn it
off.
3. Wait a few minutes until the oil set-
tles, and then check the oil level
through the check window located
at the bottom-left side of the crank-
case.
NOTE:The engine oil should be between theminimum and maximum level marks.
4. If the engine oil is at or below the
minimum level mark, add sufficient
oil of the recommended type to
raise it to the correct level.
To change the engine oil
1. Start the engine, warm it up for
several minutes, and then turn it
off.
2. Place an oil pan under the engine
to collect the used oil.1. Engine oil level check window

and drain bolt to drain the oil from
the crankcase.
4. Install the engine oil drain bolt, and
then tighten it to the specified
torque.
NOTE:Check the washer for damage and re-place it if necessary.
5. Add the specified amount of the
recommended engine oil, and then
install and tighten the oil filler cap.CAUTION:
ECA11620
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 high-
er 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.
6. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking, im-
mediately 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 theoil level is sufficient.CAUTION:
ECA10400
If the oil level warning light flickers
or remains on, immediately turn the
engine off and have a Yamaha dealercheck the vehicle.
7. Turn the engine off, and then
check the oil level and correct it if
necessary.NOTE:Have a Yamaha dealer replace the oil
filter element at the intervals specified
in the periodic maintenance and lubri-cation chart.

Final gear oil The final gear case must be checked
for oil leakage before each ride. If any
leakage is found, have a Yamaha deal-
er check and repair the vehicle. In addi-
tion, the final gear oil level must be
checked and the oil changed as follows
at the intervals specified in the periodic
maintenance and lubrication chart.
WARNING
EWA10370
Make sure that no foreign mate-
rial enters the final gear case.
Make sure that no oil gets on thetire or wheel.
To check the final gear oil level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.
NOTE:
The final gear oil level must be
checked on a cold engine.
Make sure that the vehicle is posi-
tioned straight up when checking
the oil level. A slight tilt to the sidecan result in a false reading.2. Remove the oil filler bolt, and then
check the oil level in the final gear
case.
NOTE:The oil level should be at the brim of thefiller hole.
3. If the oil is below the brim of the fill-
er hole, add sufficient oil of the rec-
ommended type to raise it to the
correct level.
To change the final gear oil
1. Place an oil pan under the final
gear case to collect the used oil.2. Remove the oil filler bolt and drain
bolt to drain the oil from the final
gear case.
3. Install the final gear oil drain bolt,
and then tighten it to the specified
torque.
4. Add the recommended final gear
oil to the brim of the filler hole.
NOTE:GL4 is a quality rating. Hypoid gear oilsrated GL5 or GL6 may also be used.
5. Install the oil filler bolt, and then
tighten it to the specified torque.

Checking the brake fluid level Front brake
Rear brake
Insufficient brake fluid may allow air to
enter the brake system, possibly caus-
ing it to become ineffective.Before riding, check that the brake fluid
is above the minimum level mark and
replenish if necessary. A low brake fluid
level may indicate worn brake pads
and/or brake system leakage. If the
brake fluid level is low, be sure to check
the brake pads for wear and the brake
system for leakage.
Observe these precautions:
When checking the fluid level,
make sure that the top of the brake
fluid reservoir is level.
Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking perfor-
mance.
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performance.
Be careful that water does not en-
ter the brake fluid reservoir when
refilling. Water will significantly
lower the boiling point of the fluid
and may result in vapor lock.
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.
As the brake pads wear, it is nor-
mal for the brake fluid level to grad-
ually go down. However, if the
brake fluid level goes down sud-
denly, have a Yamaha dealer
check the cause.

Lubricating the rear
suspension The pivoting points of the rear suspen-
sion must be lubricated at the intervals
specified in the periodic maintenance

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
WARNING
EWA10750
Securely support the vehicle so thatthere 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 vehicle on a level sur-
face and hold it in an upright posi-
tion.
2. While applying the front brake,
push down hard on the handlebars
several times to check if the front
fork compresses and rebounds
smoothly.
