TIPIf 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
specified torque as soon as possible.NOTICE
ECA10841
Do not use any tools to remove or in-
stall the spark plu g cap, otherwise
the i gnition coil coupler may get
d amag ed . The spark plu g cap may
b e difficult to remove b ecause the
ru bber seal on the en d of the cap fits
ti g htly. To remove the spark plu g
cap, simply twist it b ack and forth
while pullin g it out; to install it, twist
it back an d forth while pushin g it in.

En gine oil an d oil filter car-
tri dgeThe engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter car-
tridge replaced at the intervals speci-
fied in the periodic maintenance and
lubrication chart.
To check the en gine oil level
1. Place the vehicle on a level surfa- ce and hold it in an upright posi-
tion. 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.
3. Wait a few minutes until the oil set- tles, and then check the oil level
through the check window locat-
ed at the bottom-right side of the
crankcase.TIPThe engine oil should be between the
minimum and maximum level marks.
4. If the engine oil is below the mini-mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.
To chan ge the en gine oil (with or
without oil filter cartri dge replace-
ment) 1. Place the vehicle on a level surfa- ce.
2. Start the engine, warm it up for several minutes, and then turn it
off.
3. Place an oil pan under the engine to collect the used oil.

Final gear oilThe 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 ad-
dition, the final gear oil must be
checked and changed as follows at the
intervals specified in the periodic main-
tenance and lubrication chart.
WARNING
EWA10371
Make sure that no forei gn mate-
rial enters the final gear case.
Make sure that no oil gets on
the tire or wheel.To check the final gear oil level
1. Place the vehicle on a level surfa- ce and hold it in an upright posi-
tion.TIPMake sure that the vehicle is posi-
tioned straight up when checking the
oil level.2. Remove the final gear oil checkbolt and its gasket, and check that
oil flows out. 3. If no oil flows out, remove the final
gear case breather cap by remov-
ing the bolt and washer and then
remove the final gear oil filler bolt
and its gasket. 4. Check the gaskets for damage,
and replace them if necessary.
5. Pour the recommended type of oil in the final gear oil filler hole until it
flows out of the oil check bolt hole.
6. Install the oil check bolt, the oil fill- er bolt and their gasket, and then
tighten the bolts to the specified
torques.

TIPThe rear brake fluid reservoir is located
under the passenger seat. (See page

WARNING
EWA16011
Improper maintenance can result in
loss of b raking a bility. O bserve
these precautions: Insufficient brake flui d may al-
low air to enter the brake sys-
tem, re ducin g brakin g
performance.
Clean the filler cap before re-
movin g. Use only DOT 4 b rake
flui d from a seale d container.
Use only the specified b rake flu-
i d ; otherwise, the ru bber seals
may deteriorate, causin g leak-
a g e.
Refill with the same type of
brake flui d. A dding a brake fluid
other than DOT 4 may result in a
harmful chemical reaction.
Be careful that water or d ust
d oes not enter the brake flui d
reservoir when refillin g. Water
will si gnificantly lower the boil-
in g point of the flui d an d may re-
sult in vapor lock, an d d ir t may

NOTICE
ECA17641
Brake flui d may d amage painte d
surfaces or plastic parts. Always
clean up spilled fluid imme diately.As the brake pads wear, it is normal for
the brake fluid level to gradually go
down. A low brake fluid level may indi-
cate worn brake pads and/or brake system leakage; therefore, be sure to
check the brake pads for wear and the
brake system for leakage. If the brake
fluid level goes down suddenly, have a
Yamaha dealer check the cause before
further riding.
