Tighten the filler cap securely after
refueling.
If you should swallow some gasoline,
inhale a lot of gasoline vapor, or get
gasoline in your eyes, get immediate
medical attention.
If any gasoline spills onto your skin,
immediately wash with soap and
water. Change clothing if gasoline
spills on it.
@
CAUTION:@ Use only fresh gasoline that has been
stored in clean containers.

EJU18320
Gasohol
There are two types of gasohol: gasohol
containing ethanol and that containing meth-
anol.
Gasohol containing ethanol can be used
if ethanol content does not exceed 10% and
the fuel meets minimum octane ratings.
Gasohol containing methanol is not rec-
ommended by Yamaha because it can
cause fuel system damage or engine perfor-
mance problems. Recommended gasoline:
Regular unleaded gasoline with a
minimum octane rating of
86 (Pump octane number) = (R+M)/2
90 (Research octane number)
