Fuel cock
The fuel cock supplies fuel from the
tank to the carburetor while filtering it
also.
The fuel cock has three positions:
OFF
1. Pointed end positioned over “OFF”
With the lever in this position, fuel will
not flow. Always return the lever to
this position when the engine is not
running.ON
1. Pointed end positioned over “ON”
With the lever in this position, fuel
flows to the carburetor. Normal riding
is done with the lever in this position.
RES
1. Pointed end positioned over “RES”
This indicates reserve. If you run out
of fuel while riding, move the lever to
this position. Fill the tank at the first
opportunity. Be sure to set the lever
back to “ON” after refueling!
