Periodic maintenance and adjustment
Before installing a spark plug, the
spark plug gap should be measured
with a wire thickness gauge and, if
necessary, adjusted to specification.
1. Spark plug gap
Spark plug gap:
0.8–0.9 mm (0.031–0.035 in)

Clean the surface of the spark plug
gasket and its mating surface, and
then wipe off any grime from the spark
plug threads.
Tightening torque:
Spark plug:
13 N·m (1.3 kgf·m, 9.6 lb·ft)
TIP
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
specified torque as soon as possible.

Engine oil and oil filter ele-
ment
The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter ele-
ment replaced at the intervals specified
in the periodic maintenance and lubri-
cation chart.
To check the engine oil level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion. 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 for the oil level
to settle for an accurate reading,
and then check the oil level
through the check window locat-
ed at the bottom-right side of the
crankcase.
TIP
The engine oil should be between the
minimum and maximum level marks.
