9 Owners are personally responsible for their vehicleÕs condition. Your motorcycleÕs vital functions can start to deteriorate
quickly and unexpectedly, even if it remains unused (for instance, if it is exposed to the elements). Any damage, fluid
leak or loss of tire pressure could have serious consequences. Therefore, it is very important that, in addition to a thor-
ough visual inspection, you check the following points before each ride.

Transmission oilOil level inspection
1.Place the motorcycle on a level
place and hold it in an upright
position. Warm up the engine for
several minutes.NOTE:
Be sure the motorcycle is positioned
straight up when checking the oil
level. A slight tilt toward the side can
result in false readings.1.Level window

3.Minimum level
Installation
1.Measure the electrode gap with
a wire thickness gauge and, if
necessary, adjust the gap to
specification.
2.Clean the gasket surface. Wipe
off any grime from the threads.
3.Install the spark plug and tighten
it to the specified torque.

1.Spark plug gap
NOTE:
If a torque wrench is not available
when you are installing a spark plug,
a good estimate of the correct torque
is 1/4 to 1/2 turn past finger tight.
Have the spark plug tightened to the
specified torque as soon as possible.4.Install the spark plug cap.

to reach the specified level.
Install the oil filler cap and tight-

cCDo not put in any chemical addi-
tives. Transmission oil also lubri-
cates the clutch and additives
could cause clutch slippage.6.Start the engine and warm up for
a few minutes. While warming
up, check for oil leakage. If oil
leakage is found, stop the engine
immediately and check for
cause. Recommended oil:
See page 8-1.
Oil quantity:
Total amount: 0.8 L
Periodic oil change: 0.75 L

Transmission oil replacement
1.Warm up the engine for several
minutes.
2.Stop the engine. Place an oil pan
under the engine to catch the oil
and remove the oil filler cap.
3.Remove the drain bolt and drain
the oil.
4.Install the drain bolt and tighten it
to the specified torque.1.Drain bolt

2.With the engine stopped, check
the oil level through the level
window located at the right side
crankcase cover.NOTE:
Wait a few minutes until the oil level
settles before checking.3.The oil level should be between
the maximum and minimum level
on the level window. If the level
is low, add sufficient oil to raise it
to the specified level.1.Oil filler cap

98Use only the designated quality
brake fluid. Otherwise, the rub-
ber seals may deteriorate, caus-
ing leakage and poor brake per-
formance.
NOTE:
If DOT 4 is not available, DOT 3 can
be used.
EAU00732
Inspecting the brake fluid
levelInsufficient brake fluid may let air
enter the brake system, possibly
causing the brakes to become inef-
fective.
Before riding, check that the brake
fluid is above the minimum level and
fill when necessary.
Observe these precautions:
8When checking the fluid level,
make sure the top of the master
cylinder is level by turning the
handlebars.

DOT 4
8Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor brake performance.
8Be careful that water does not
enter the master cylinder when
refilling. Water will significantly
lower the boiling point of the fluid
and may result in vapor lock.
8Brake fluid may deteriorate paint-
ed surfaces or plastic parts.
Always clean up spilled fluid
immediately.
8Have a Yamaha dealer check
the cause if the brake fluid level
goes down.
