Check the fuel tank breather hose
for cracks or damage, and replace
it if damaged.


Make sure that the end of the fuel
tank breather hose is not blocked,
and clean it if necessary.

Fuel cock The fuel cock supplies fuel from the
tank to the carburetor while filtering it al-
so.
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 running.ON
With the lever in this position, fuel flows
to the carburetor. Normal riding is done
with the lever in this position.
