es or plastic parts.

CAUTION:
ECA11400
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,
as well as to the exhaust system.
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 contain-
ing methanol. Gasohol containing
ethanol can be used if the ethanol con-
tent does not exceed 10%. Gasohol
containing methanol is not recom-
mended by Yamaha because it can
cause damage to the fuel system or ve-
hicle performance problems.

The fuel cock lever positions are ex-
plained as follows and shown in the il-
lustrations.

With the fuel cock lever in this position,

ver to this position when starting the en-
gine and riding.
