Fuel cock

This motorcycle is equipped with a
negative pressure fuel cock. The fuel
cock supplies fuel from the tank to the
carburetors while also filtering it.
The fuel cock lever positions are ex-
plained as follows and shown in the
illustrations.
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
engine and riding.
RES: reserve position
1. Arrow mark positioned over "RES"
RES
EAU03236
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"!
PRI: priming position
1. Arrow mark positioned over "PRI"
PRI
This indicates prime. With the fuel cock
lever in this position, the engine can be
"primed". Turn the fuel cock lever to
this position when the engine has been
allowed to run out of fuel. This sends
fuel directly to the carburetor, which will
make starting easier. After the engine
has started, be sure to turn the lever to
"ON" (or "RES" if you have not refueled
yet).
