6Installation
1. Measure the electrode gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifica-
tion.
2. Clean the gasket surface. Wipe off
any grime from the threads.
3. Install the spark plug and tighten it
to the specified torque.
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 caps.

Engine oilOil level inspection
1. Place the motorcycle on the cen-
terstand. 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. @

the oil level through the level win-
dow located at the lower part of
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
marks. If the level is low, add suffi-
cient oil to raise it to the specified
level.Engine oil and oil filter element re-
placement
1. Warm up the engine for several
minutes.
2. Stop the engine. Place an oil pan
under the engine and remove the
oil filler cap.
3. Remove the drain bolt and drain
the oil.4. Remove the oil filter drain screw,
filter cover bolt, filter cover, oil filter
element and O-ring.

it to the specified torque.1. Oil level window

Inspecting the brake fluid levelInsufficient brake fluid may let air enter
the brake or clutch system, possibly
causing them to become ineffective.
Before riding, check that the brake fluid
is above the minimum level and fill
when necessary. Low brake fluid levels
may indicate worn brake pads and/or
fluid leakage. If the brake fluid level is
low, be sure to inspect the brake pads
for wear and the brake and clutch sys-
tems for leakage.NOTE:The rear master cylinder is located be-
hind panel A.
Observe these precautions:l
When checking the fluid level,
make sure the top of the master
cylinder is level by turning the han-
dlebars.
l
Use only the designated quality
brake fluid. Otherwise, the rubber
seals may deteriorate, causing
leakage and poor brake or clutch
performance.
l
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor brake or clutch perfor-
mance.
l
Be careful that water does not en-
ter the master cylinder when refill-
ing. Water will significantly lower
the boiling point of the fluid and
may result in vapor lock.
l
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.
l
Have a Yamaha dealer check the
cause if the brake fluid level goes
down.
