Your Yamaha engine has been de-
signed to use regular unleaded gaso-
line with a pump octane number
[(R+M)/2] of 86 or higher, or a research
octane number of 91 or higher. If
knocking (or pinging) occurs, use a
gasoline of a different brand or premi-
um unleaded fuel. Use of unleaded fuel
will extend spark plug life and reduce
maintenance costs.
Gasohol
There are two types of gasohol: gaso-
hol containing ethanol and that con-
taining methanol. Gasohol containing
ethanol can be used if the ethanol con-
tent does not exceed 10% (E10). Gas-
ohol containing methanol is not
recommended by Yamaha because it
can cause damage to the fuel system
or vehicle performance problems.

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-
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.
