CAUTION:

Be sure to use motor oils that do not contain
anti-friction modifiers. Passenger car motor
oils (often labeled “Energy Conserving”) con-
tain anti-friction additives which will cause
clutch and/or starter clutch slippage, resulting
in reduced component life and poor engine
performance.

check the chain slack before every ride. Lubri-
cate and adjust the chain as necessary. (See
pages 8-57 ~ 8-61 for details.)Oil quantity:

Engine oil
Engine oil level measurement
1. Place the ATV on a level surface.
2. Warm up the engine for several minutes,
and then stop it.
3. Remove the dipstick, and then wipe it off
with a clean rag. Insert the dipstick in the
filler hole without screwing it in.
NOTE:

Wait a few minutes until the oil level settles be-
fore checking.
4. Remove the dipstick, and then check the
oil level.
5. The oil level should be between the maxi-
mum and minimum marks. If the level is
low, add oil to raise it to the proper level.
CAUTION:

Be sure no foreign material enters the crank-
case.

Oil pressure check
1. Put a cloth around the cylinder.
2. Slightly loosen the oil gallery bolt in the
cylinder head.
3. Start the engine and keep it idling until oil
begins to seep from the oil gallery. If no oil
comes out after one minute, turn the en-
gine off so it will not seize and find the
cause.
4. Start the engine, and then check the oil
pressure.
5. After checking, tighten the oil gallery bolt
to the specified torque.CAUTION:Be sure to check the oil pressure after replac-ing the engine oil. Tightening torque:
Oil gallery bolt:
7 Nm (0.7 m·kg)
