● Oxygenated fuels (gasohol) containing
a maximum 10% of ethanol (E10) can be
used, although richer jetting may be re-
quired to prevent engine damage. Con-
sult a Yamaha dealer. Gasohol

ed.
● Make sure that snow or ice does not en-
ter the fuel tank when refueling.
● Do not use alcohol deicers or water ab-
sorbing additives with oxygenated fuel.

recommended gasoline. The use of oth-
er gasoline will cause severe damage to
internal engine parts, such as the valves
and piston rings, as well as to the ex-
