Spark plug inspection
The spark plug is an important
engine component and should be
inspected periodically, preferably by
a Yamaha dealer. The condition of
the spark plug can indicate the condi-
tion of the engine. The ideal color on
the white insulator around the center
electrode is a medium-to-light tan
color for a motorcycle that is being
ridden normally. Do not attempt to
diagnose any problems yourself.
Instead, take the motorcycle to a
Yamaha dealer. The spark plug
should be periodically removed and
inspected because heat and depositswill cause the spark plug to slowly
break down and erode. If electrode
erosion becomes excessive, or if car-
bon and other deposits are exces-
sive, the spark plug should be
replaced with the specified plug.
Before installing the spark plug, mea-
sure the electrode gap with a wire
thickness gauge and adjust it to
specification.When installing the plug, the gasket
surface should always be cleaned
and a new gasket used. Any grime
should be wiped off from the threads
and the spark plug tightened to the
specified torque.NOTE:
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is 1/4
to 1/2 turn past finger tight. The spark
plug should be tightened to the speci-
fied torque as soon as possible.

1. Transmission oil filler cap
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 above the
minimum level mark on the level
window. If the level is low, add
sufficient oil to raise it to the
proper level.Transmission oil replacement
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.

Oil level measurement
1. Place the motorcycle on a level
place and hold it an upright posi-
tion. 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.

Do not put in any chemical
additives. Transmission oil
also lubricates the clutch and

Be sure no foreign material
enters the crankcase.
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.

EAU01621*Cooling system
1. Check the coolant level in the
reservoir tank when the engine is
cold as the coolant level will vary
with engine temperature. The
coolant level should be between
the minimum and maximum
marks on the tank.
2. If the coolant level is at or below
the minimum mark, fill with tap
water (soft water) to bring the
level up to the specified level.
Change the coolant every two
years.
3. If your motorcycle overheats, see
page 6-38 for details.
