Fuel requirements
EMU44791
Gasoline
Use a good quality gasoline that meets the
minimum octane requirement. If knocking or
pinging occurs, use a different brand of gas-
oline or premium unleaded fuel. Yamaha rec-
ommends that you use alcohol-free gasoline
(see Gasoline with Ethanol) whenever possi-
ble.
The use of a poor quality gasoline may result
in starting and running problems. If you en-
under
counter drivability problems, which you sus-
pect could be related to the fuel you are
using, Yamaha recommends that you switch
to a recognized high quality brand of gaso-
line, such as a gasoline that is advertised as
Top Tier Detergent Gasoline. (North America
