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.EBU27468Engine 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. Check the engine oil level on a cold engine.
TIPIf the engine was started before checking the oil
level, be sure to warm up the engine sufficiently,
and then wait at least 10 minutes until the oil set-
tles for an accurate reading. 3. Remove the access cover by turning it coun- terclockwise.
4. Remove the engine oil dipstick, and then wipe it off with a clean rag.
Tightening torque:

8To change the engine oil (with or without oil fil-
ter cartridge replacement)

2. Remove the access cover by turning it coun- terclockwise.
3. Place an oil pan under the engine to collect the used oil.
4. Remove the dipstick, and then remove the engine oil drain bolt and its gasket to drain the
oil from the crankcase.
TIPSkip steps 5–9 if the oil filter cartridge is not being
replaced. 5. Remove panel F. (See page 8-10.)
6. Remove the oil filter cartridge with an oil filterwrench.TIPAn oil filter wrench is available at a nearby Yamaha

torque with a torque wrench. 9. Install panel F.

ified torque.1. O-ring

811. Refill with the specified amount of the recom-
mended engine oil, and then insert the dip-
stick completely into the oil filler hole.
TIPBe sure to wipe off spilled oil on any parts after the
engine and exhaust system have cooled down. NOTICEECB00301In 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. 
Make sure that no foreign material enters the
crankcase.
12. Start the engine, and then let it idle for several
minutes while checking it for oil leakage. If oil
is leaking, immediately turn the engine off and
check for the cause.
13. Turn the engine off, wait at least ten minutes, and then check the oil level and correct it if
necessary.
14. Install the access cover by turning it clock- wise.EBU27307Final gear oilThe final gear case must be checked for oil leak-
age before each ride. If any leakage is found, have
a Yamaha dealer check and repair the ATV. In ad-
dition, the final gear oil level must be checked and
the oil changed as follows at the intervals speci-
fied in the periodic maintenance and lubrication
chart.
To check the final gear oil level1. Place the ATV on a level surface.
Recommended oil:
See page 10-1.
Oil quantity: Without oil filter cartridge replacement:2.00 L (2.11 US qt, 1.76 Imp.qt)
With oil filter cartridge replacement: 2.10 L (2.22 US qt, 1.85 Imp.qt)

6. Wash the sponge material gently, but thor-
oughly, in solvent. WARNING! Always use
parts cleaning solvent to clean the sponge
material. Never use low-flash-point sol-
vents or gasoline to clean the sponge ma-
terial because the engine could catch fire
or explode.
[EWB01942]
7. Squeeze the excess solvent out of the sponge material and let it dry. NOTICE: Do
not twist the sponge material when
squeezing it.
[ECB00442]
8. Check the sponge material and replace it if damaged.
9. Apply Yamaha foam air filter oil or other qual- ity foam air filter oil to the sponge material.
TIPThe sponge material should be wet but not drip-
ping. 10. Install the mesh and the sponge material into the air filter case. NOTICE: Make sure that
the air filter element is properly seated in
the air filter case. Never operate the en-
gine with the air filter element removed.
This will allow unfiltered air to enter the en-
gine, causing rapid engine wear and pos-
sible engine damage. Additionally,
operation without the air filter element will
affect the fuel injection system with subse-
quent poor performance and possible en-
gine overheating.
[ECB00762]
11. Insert the projections on the air filter case cover into the holders on the air filter case,
and then install the air filter case cover by
hooking the holders onto the cover.
