ASSEMBLY
REPLACING PACKING LUBRICANT
The dirt bike engine is shipped with packing lubricant in it. This
lubricant must be drained and replaced with new engine lubri-
cant before attempting to operate the dirt bike. Do not start
the engine while it still contains the packing lubricant.
Always use a 4-stroke motor lubricant that meets or exceeds
the requirements for API service classification SJ.

CHANGING/ADDING ENGINE LUBRICANT
To check lubricant level:

Park vehicle on level ground and lower side stand.

Start the engine and allow it to run for 3 to 5 minutes.

Turn the engine off and allow to cool for at least 3 minutes.

Unscrew the oil cap/dipstick and remove.

Wipe dipstick clean and re-seat in hole, but do not re-
thread.

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 and lower side stand.

Start the engine and allow it to run for 3 to 5 minutes.

Turn the engine off and allow to cool for at least 3 minutes.

Remove oil cap.

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.
