8To 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.
TIPIf a torque wrench is not available when installing
the 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 speci-
fied torque as soon as possible. 3. Install the spark plug cap.
4. Install the panel.EBU30241Engine oil and oil filter cartridgeThe engine oil level should be checked before
each ride. In addition, the oil must be changed and
the oil filter cartridge replaced at the intervals
specified in the periodic maintenance and lubrica-
tion chart.
To check the engine oil level1. Place the ATV on a level surface.
2. Remove panel E. (See page 8-10.)
3. Check the engine oil level on a cold engine.
1. Spark plug gapSpark plug gap: 0.6–0.7 mm (0.024–0.028 in)
Tightening torque:Spark plug:18 Nm (1.8 m·kgf, 13 ft·lbf)

88. Install the panel.
To change the engine oil (with or without oil fil-
ter cartridge replacement) 1. Place the ATV on a level surface.
2. Remove panel E. (See page 8-10.)
3. Start the engine, warm it up for several min- utes, and then turn it off.
4. Place an oil pan under the engine to collect the used oil.
5. Remove the engine oil filler cap, and then re- move the engine oil drain bolt and its gasket
to drain the oil from the crankcase.
TIPSkip steps 6–10 if the oil filter cartridge is not be-
ing replaced. 6. Remove panels C and D. (See page 8-10.)
7. Remove the oil filter cartridge with an oil filterwrench.

TIPMake sure that the O-ring is properly seated. 9. Install the new oil filter cartridge with an oil fil-ter wrench, and then tighten it to the specified
torque with a torque wrench.

ified torque. 12. Refill with the specified amount of the recom-
mended engine oil, and then install and tight-
en the engine oil filler cap.
TIPBe sure to wipe off spilled oil on any parts after the
engine and exhaust system have cooled down. NOTICEECB00301In order to prevent clutch slippage (since the
engine oil also lubricates the clutch), do not
mix any chemical additives. Do not use oils
with a diesel specification of “CD” or oils of
a higher quality than specified. In addition,
do not use oils labeled “ENERGY CONSERV-
ING II” or higher.

Oil filter cartridge:17 Nm (1.7 m·kgf, 12 ft·lbf)
Tightening torque: Engine oil drain bolt:23 Nm (2.3 m·kgf, 17 ft·lbf)
Recommended oil:See page 10-1.
Oil quantity: Without oil filter cartridge replacement:2.30 L (2.43 US qt, 2.02 Imp.qt)
