Fuel cock
This model is equipped with a negative
pressure fuel cock. The fuel cock sup-
plies fuel from the tank to the carburetor
while also filtering it.
The fuel cock lever positions are ex-
plained as follows and shown in the il-
lustrations.
ON
With the fuel cock lever in this position,
fuel flows to the carburetor when the
engine is running. Turn the fuel cock le-
ver to this position when starting the en-
gine and riding.
RES
This indicates reserve. With the fuel
cock lever in this position, the fuel re-
serve is made available. Quickly turn
the fuel cock lever to this position if you
run out of fuel while riding, otherwise
the engine may stall and will have to be
primed (see PRI). After turning the
fuel cock lever to RES, refuel as soon
as possible and be sure to turn the fuel
cock lever back to ON!
