MAINTENANCE

CHECKING THE OIL

Check engine oil each time prior to operating dirt bike.

The oil level should be between the upper and lower lines of oil gauge fitted in a 
screw plug, which is on right cover of crankcase.

1.  Set dirt bike on level ground. Look at sight gauge for current oil level. You 

can also remove dipstick plug, wipe it clean and then reinsert into crankcase. 
Remove dipstick to check oil level.

2.  Add lubricating oil up to the upper line when needed, but do not overfill.

3.  Finally reinstall dip stick plug and cinch finger tight.

Lubricating Oil Recommended

The lubricating oil is an important factor affecting performance and service life 
of engine. Please refer to the chart for correct grade of engine oil based on the 
environmental conditions in your area.   Do not use any other type of oil other than 
what is recommended in the chart.  DO NOT MIX OIL WITH THE GASOLINE.

Lubricating oils of different 
viscosity should be employed 
in different regions and at 
different temperatures.
