1. Spark plug gap
Spark plug gap:
0.6~0.7mm (0.024-0.028 in)
2. Clean the surface of the spark plug
gasket and its mating surface, and
then wipe off any grime from the
spark plug threads.
3. Install the spark plug with the
spark plug wrench, and then
tighten it to the specified torque.
Tightening torque:
Spark plug:
17.5 Nm (1.75 m.kgf, 13 ft.lbt)
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
element
The 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
General periodic maintenance and
lubrication chart.
To check the engine oil level
1. Place the vehicle on a level
surface and hold it in an upright
position.
Make sure that the vehicle 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.
