Fuel filling
The capacity of the fuel tank is 6.0L. Unscrew the gas cap by turning
it counter clockwise and carefully fill the tank with unleaded gasoline through
the opening. DO NOT MIX GAS AND OIL TOGETHER, THIS IS A 4-STROKE
ENGINE. Replace the gas cap by carefully aligning the threads on the cap
and the tank and turning the cap clock wise. Wipe any spilled fuel from the
dirt bike using a cloth and dispose of the cloth properly. DO NOT SMOKE
OR REFUEL THE VEHICLE NEAR OPEN FLAMES OR NEAR HEATING UNITS.
ONLY REFUEL THE VEHICLE IN OPEN AREAS TO REDUCE THE LIKELIHOOD
OF THE BUILD UP OF GASOLINE FUMES.
Operation of the fuel valve (the valve under the fuel tank)
ON: With the handle of the fuel valve at “ON” position, the fuel supply will
flow to the carburetor.
OFF: With the handle of the fuel valve at “OFF” position, the fuel supply will
not flow to the carburetor.
RES: If fuel level in the fuel tank becomes too low for engine to stay running
while fuel valve is at “ON” position, turn fuel valve to “RESERVE”. Turning
fuel valve to “RESERVE” will allow engine to begin using reserve fuel supply.
You will need to re-fuel as soon as possible. There is approximately 1L of fuel
left in tank when fuel valve is placed at “RESERVE”. Once re-fueled, turn fuel
valve back to the “ON “ Position
