CHECk-UPS, ADJUSTMENT AND MAINTENANCE
Checking the Oil
Check the engine oil each time prior to operating the dirt bike.
The oil level should be between the upper and lower lines of the oil sight
gauge located on the right cover of the crankcase. The level can also be
checked on the dip stick.
1. Set the motorcycle on level ground, look at the sight gauge for current oil
level. Remove the oil gage plug, wipe the oil gage rod clean and then
insert the gage plug into the crankcase again to check the oil level. There
is no need to completely install the oil gage plug in the crankcase fill
hole.
2. Add lubricating oil up to the upper line when needed, but do not overfill.
3. Finally screw on the oil gage plug tightly.
Lubricating Oil Recommended
The lubricating oil is an important factor affecting the performance and
service life of the engine. Please refer to the chart for the 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 shall be employed
in different regions and at
different temperatures.
CAUTION
Never start the engine when there is
insufficient lubricating oil. Otherwise,
it will cause harm to the engine.
