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