3. Install the spark arrester and secure with the cap
screw. Tighten securely.
Engine Oil - Filter
Replace the engine oil and clean the screen/filter at the
scheduled intervals. The engine should always be warm
when the oil is changed so the oil will drain easily and
completely.
1. Park the ATV on level ground.
2. Loosen the oil fill plug.

4. Clean the screen/filter in parts-cleaning solvent; then
inspect the O-ring and replace if damaged.
5. Install the screen/filter, spring, and screen/filter cap
into the crankcase and tighten to 11 ft-lb.
6. Remove the oil fill plug and pour in 1.0 L (1.06 U.S.
qt) of the recommended oil into the fill hole; then
install the oil fill plug.
7. Start the engine (while the ATV is outside on level
ground) and allow it to idle for a few minutes.
8. Turn the engine off and wait approximately one min-
ute. Check the oil level in the engine oil inspection
window. The oil level should be visible through the
window. If oil is not visible, add recommended oil
until the oil level is visible between the lines of the
window.
! WARNING
Wait until the muffler cools to avoid burns.
CAUTION
Any oil used in place of the recommended oil could
cause serious engine damage. Do not use oils which
contain graphite or molybdenum additives. These oils
can adversely affect clutch operation. Also, not recom-
mended are racing, vegetable, non-detergent, and cas-
tor-based oils.
