NOTICE
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 research octane
number of 91 or higher. If knocking (or pinging) oc-
curs, use a gasoline of a different brand. Use of un-
leaded fuel will extend spark plug life and reduce
maintenance costs.
