Fuel
Make sure there is sufficient gasoline in the
tank.
CAUTION:
_
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 designed to
use regular unleaded gasoline with a pump
octane number ([R+M]/2) of 86 or higher, or
research octane number of 91 or higher. If
knocking or pinging occurs, use a different
brand of gasoline or premium unleaded fuel.
Unleaded fuel will give you longer spark plug
life and reduced maintenance cost.
Gasohol
There are two types of gasohol; gasohol con-
taining ethanol and that containing methanol.
Gasohol containing ethanol can be used if
ethanol content does not exceed 10%. Gaso-
hol containing methanol is not recommended
by Yamaha because it may cause fuel system
damage or vehicle performance problems.
Recommended fuel:
UNLEADED GASOLINE ONLY
Fuel tank capacity:
30.0 L (6.60 Imp gal, 7.93 US gal)
