cCUse 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
research octane number of 91 or higher.
If knocking (or pinging) occurs, use a
gasoline of a different brand or premium
unleaded fuel. Use of unleaded fuel will
extend spark plug life and reduce main-
tenance costs.
