NOTE:
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is
1/4Ð1/2 turn past finger tight.
However, the spark plug should be
tightened to the specified torque as
soon as possible.4.Install the spark plug cap. Tightening torque:
Spark plug:
12.5 Nm (1.25 m0kg)

Engine oil and oil filter
elementThe engine oil level should be
checked before each ride. In addition,
the oil must be changed and the oil
filter element replaced at the intervals
specified in the periodic maintenance
and lubrication chart.
To check the engine oil level
1.Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:
Make sure that the motorcycle is
positioned 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.3.Wait a few minutes until the oil
settles, and then check the oil
level through the check window
located at the bottom-right side
of the crankcase.
NOTE:
The engine oil should be between the
minimum and maximum level marks.4.If the engine oil is below the min-
imum level mark, add sufficient
oil of the recommended type to
raise it to the correct level.

PERIODIC MAINTENANCE AND MINOR REPAIR
Observe these precautions:
8When checking the fluid level,
make sure that the top of the
brake fluid reservoir is level.
8Use only the recommended qual-
ity brake fluid, otherwise the rub-
ber seals may deteriorate, caus-
ing leakage and poor braking
performance.
8Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking perfor-
mance.
8Be careful that water does not
enter the brake fluid reservoir
when refilling. Water will signifi-
cantly lower the boiling point of
the fluid and may result in vapor
lock. Recommended brake fluid:
DOT 4
8Brake fluid may deteriorate paint-
ed surfaces or plastic parts.
Always clean up spilled fluid
immediately.
8As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if
the brake fluid level goes down
suddenly, have a Yamaha dealer
check the cause.
EAU03238
Changing the brake fluidHave a Yamaha dealer change the
brake fluid at the intervals specified in
the periodic maintenance and lubrica-
tion chart. In addition, have the oil
seals of the brake master cylinder
and caliper as well as the brake hose
replaced at the intervals listed below
or whenever they are damaged or
leaking.
8Oil seals: Replace every two
years.
8Brake hose: Replace every four
years.

cCBe sure to use motor oils that do not contain anti-friction
modifiers. Passenger car motor oils (often labeled ÒEnergy
ConservingÓ) contain anti-friction additives which will cause
clutch and/or starter clutch slippage, resulting in reduced
component life and poor engine performance.
