TIPIf 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.4. Install the spark plug cap.EBU27463Engine oil and oil filter cartridge The 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 spec-
ified 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.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 settles
for an accurate reading.
3. Remove panel F. (See page 8-8.)
4. Remove the engine oil dipstick, and then wipe
it off with a clean rag.
5. Insert the dipstick completely into the oil filler
hole, and then remove it again to check the oil
level.1. Engine oil dipstick

TIPThe engine oil should be between the minimum
and maximum level marks.6. If the engine oil is at or below the minimum
level mark, add sufficient oil of the recom-
mended type to raise it to the correct level.
NOTICE: Be sure the engine oil is at the
correct level, otherwise engine damage
may result.
[ECB00851]
7. Insert the dipstick completely into the oil filler
hole.
8. 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 F. (See page 8-8.)
3. Place an oil pan under the engine to collect
the used oil.
4. Remove the dipstick, and then remove the en-
gine oil drain bolt to drain the oil from the
crankcase.
TIPSkip steps 5–9 if the oil filter cartridge is not being
replaced.5. Remove panel G. (See page 8-8.)

86. Remove the oil filter cartridge with an oil filter
wrench.
TIPAn oil filter wrench is available at a nearby Yamaha
dealer.7. Apply a thin coat of engine oil to the O-ring of
the new oil filter cartridge.
TIPMake sure that the O-ring is properly seated.8. Install the new oil filter cartridge with an oil fil-
ter wrench, and then tighten it to the specified
torque with a torque wrench.

9. Install panel G.
10. Install the engine oil drain bolt, and then tight-
en it to the specified torque.11. 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.NOTICEECB00300In 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.

85. Clean the mesh with solvent, and then wipe
the solvent off.
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.
[EWB01941]
7. Squeeze the excess solvent out of the sponge
material and let it dry. NOTICE: Do not twist
the sponge material when squeezing it.
[ECB00441]
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 engine
with the air filter element removed. This
will allow unfiltered air to enter the engine,
causing rapid engine wear and possible
