CHECk-UPS, ADJUSTMENT AND 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, screw off oil gage plug, wipe oil gage rod clean
and insert gage plug into crankcase again to check oil level. There is no need
to screw oil gage plug into its hole in crankcase.
2. Add lubricating oil up to the upper line when needed, but do not overfill.
3. Finally screw on oil gage plug tightly.
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.
