CAUTION:
ECA10070
Immediately wipe off spilled fuel
with a clean, dry, soft cloth, since
fuel may deteriorate painted surfac-
es or plastic parts.
EAU41980
For Canada
CAUTION:
ECA15590
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the 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. Ifknocking (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 cost.
Gasohol
There are two types of gasohol: gaso-
hol containing ethanol and that contain-
ing methanol. Gasohol containing
ethanol can be used if ethanol content
does not exceed 10%. Gasohol con-
taining methanol is not recommended
by Yamaha because it can cause dam-
age to the fuel system or vehicle perfor-
mance problems.
Except for Canada

curs, use a gasoline of a different brand
or premium unleaded fuel. Use of un-
leaded fuel will extend spark plug life
and reduce maintenance costs.
