To install the spark plug
1. Clean the surface of the spark plug gasket
and its mating surface, and then wipe off any
grime from the spark plug threads.
2. Install the spark plug with the spark plug
wrench, and then tighten it to the specified
torque.
Tightening torque:
Spark plug:
12 N·m (1.2 kgf·m, 8.7 lb·ft)
TIP
If a torque wrench is not available when installing
the spark plug, a good estimate of the correct
8
torque is 1/4–1/2 turn past finger tight. However,
the spark plug should be tightened to the speci-
fied torque as soon as possible.

Engine oil

The engine oil level should be checked before
each ride. In addition, the oil must be changed at
the intervals specified in the periodic maintenance
and lubrication chart.
To check the engine oil level
1. Place the ATV on a level surface.
2. Check the engine oil level on a cold engine.
TIP
If the engine was started before checking the oil
level, warm up the engine and then wait at least
ten minutes until the oil settles for an accurate
reading.
3. Remove the engine oil filler cap, and then
wipe the engine oil dipstick off with a clean
rag.
