 Remove the dipstick and inspect the lubricant level. Level
should be between the minimum and maximum marks on
the dipstick.
 If lubricant is below minimum mark on dipstick, add lu-
bricant until level falls between minimum and maximum
marks on the dipstick.
To change engine lubricant:
Lubricant should be changed while the engine lubricant is still
warm, but not hot. This allows the lubricant to drain quickly
and completely.
 Park vehicle on level ground.
 Remove oil cap/dipstick.
 Place a container underneath the oil drainage bolt to col-
lect used lubricant as it drains.
 Unscrew the oil drainage bolt and remove the bolt and
washer.
 Allow lubricant to drain completely.
 Reinstall washer and oil drainage bolt. Torque oil drainage
bolt to 18 ft.lbs. (24 Nm).
 Fill crankcase with 0.90 qt. (0.85 l) SAE15W40 lubricant.
NOTE: Used lubricant should be disposed of at an approved
disposal site. See your local oil retailer for more information.
MAINTENANCE
CHECKING/CLEANING AIR FILTER
The air filter element must be kept clean to provide good
engine power. If you use your vehicle under normal, low-
tension conditions, you should service the air filter at the
intervals specified. If you ride in dusty, wet, or muddy con-
ditions, you will need to inspect the air filter element much
more frequently.
CAUTION:
Always check the air filter element after riding in severe
conditions and clean or replace as needed. Operating
the dirt bike with a clogged air filter could cause engine
damage.
Air filter removal and cleaning:
 Remove bolt and washer from both rear panels and set
aside.
NOTE: Rear panel is shown removed only so you can
see location of air filter box. Panel does not need to be
removed to access the box.
 Remove seat to gain access to the air filter box.
 Remove the air filter assembly. Separate the assembly
pieces to allow the foam filter elements to be cleaned.
 Wash each element in a mild non-flammable solvent.
 Squeeze out solvent by pressing the element between the
palms of both hands. Do not twist or wring the element or
it will develop cracks.
 Immerse the element in oil, then squeeze as before to
remove excess. The element should be damp with oil but
not soaked.
 Stack the filter elements together as shown and squeeze
together to secure.
 Replace the air filter assembly in the box. Make sure the
element is securely in position.
 Replace seat and reinstall washer and bolt to secure.
NOTE: Do not operate the engine without the air filter ele-
ments in place. Rapid engine wear will result.
