6Before installing a spark plug, the spark
plug gap should be measured with a
wire thickness gauge and, if necessary,
adjusted to specification.
Clean the surface of the spark plug
gasket and its mating surface, and then
wipe off any grime from the spark plug
threads.
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.

Engine oil and oil filter car-
tridge The 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 engine oil level
1. Place the vehicle on the center-
stand.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 below the mini-
mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.
To change the engine oil (with or
without oil filter cartridge replace-
ment)
1. Place the vehicle on a level sur-
face.2. Start the engine, warm it up for
several minutes, and then turn it

3. Place an oil pan under the engine
to collect the used oil.
4. Remove the engine oil filler cap
and drain bolt to drain the oil from
the crankcase.
NOTE:Skip steps 5–7 if the oil filter cartridge isnot being replaced.
5. Remove the oil filter cartridge with
an oil filter wrench.
NOTE:An oil filter wrench is available at aYamaha dealer.

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.

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:

If the oil level warning light flickers
or remains on, immediately turn the
engine off and have a Yamaha dealercheck the vehicle.11. Turn the engine off, and then
check the oil level and correct it if
necessary.

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 must be changed
as follows at the intervals specified in
the periodic maintenance and lubrica-
tion 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 the center-
stand.
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.

The YCC-S clutch fluid reservoir is
located behind panel B. (See page6-7.)
Observe these precautions:
When checking the fluid level,
make sure that the top of the brake
and YCC-S clutch fluid reservoirs
are level.
Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking or
YCC-S clutch performance.
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking or YCC-S
clutch performance.
The brake and YCC-S clutch fluid
reservoir diaphragms will lose their
shape from the negative pressure
if the fluid level goes down too far.Be sure to return the diaphragms
to their original shape before rein-
stalling them.
Be careful that water or dust does
not enter the brake and YCC-S
clutch fluid reservoirs when refill-
ing. Water will significantly lower
the boiling point of the fluid and
may result in vapor lock, and dirt
may clog the ABS hydraulic unit
valves.
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.
EAU40600
Changing the brake and
YCC-S clutch fluids Have a Yamaha dealer change the
brake and YCC-S clutch fluids at the in-
tervals specified in the NOTE after the
periodic maintenance and lubrication
chart. In addition, have the oil seals of
the brake and YCC-S clutch master cyl-
inders and calipers as well as the brake
and YCC-S clutch hoses replaced at
the intervals listed below or whenever
they are damaged or leaking.
Oil seals: Replace every two
years.
Brake and YCC-S clutch hoses:
Replace every four years.
Recommended brake and YCC-S
clutch fluid:
DOT 4 brake fluid

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.
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 unsafeconditions.

Checking and lubricating the
throttle grip and cable The operation of the throttle grip should
