Instrument and control functions

Fuel cock

This model is equipped with a negative
pressure fuel cock. The fuel cock sup-
plies fuel from the tank to the carbure-
tor while also filtering it.
The fuel cock lever positions are ex-
plained as follows and shown in the il-
4 lustrations.
ON
1. Arrow mark positioned over "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
EAU13582
1. Arrow mark positioned over "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
1
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
1
1. Arrow mark positioned over "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 en-
gine has started, be sure to turn the le-
ver to "ON" (or "RES" if you have not
refueled yet).
