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.
 Hold the mini bike upright, 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/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.
 Inspect sealing washer and replace if damaged.
NOTE: This should be replaced at least every other time
the lubricant is changed.
 Reinstall washer and oil drainage bolt. Torque oil drainage
bolt to 18 ft.lbs. (24 Nm).
 Fill crankcase with 0.40 qt. (0.45 l) of SAE15W40 lubricant.
 Reinstall the oil cap/dipstick.
 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.
 Hold the mini bike upright and recheck the lubricant level.
 Make sure there are no leaks.
NOTE: Used lubricant should be disposed of at an approved
disposal site. See your local oil retailer for more information.
CAUTION:
Attempting to start the engine before it has been properly
filled with lubricant will result in equipment failure.
