OPERATION
FUEL VALVE
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.
