CAUTION:_ Use only unleaded gasoline. The
use of leaded gasoline will cause se-
vere damage to internal engine
parts, such as the valves and piston
rings, as well as to the exhaust sys-
tem. _Your Yamaha engine has been de-
signed to use regular unleaded gaso-
line with a research octane number of
91 or higher. If knocking (or pinging)
occurs, use a gasoline of a different
brand or premium unleaded fuel. Use
of unleaded fuel will extend spark plug
life and reduce maintenance costs.
EAU04484
Fuel cock This motorcycle is equipped with a
negative pressure fuel cock. The fuel
cock supplies 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
engine 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”! Recommended fuel:

make starting easier. After the engine
has started, be sure to turn the lever to
“ON” (or “RES” if you have not refueled
yet).
