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 a research oc-
tane number of 91 or higher. If knocking or pinging
occurs, use a different brand of gasoline or premi-
um unleaded fuel. Unleaded fuel will give you long-
er spark plug life and reduced maintenance cost.
Gasohol
There are two types of gasohol: gasohol contain-
ing ethanol and that containing methanol. Gasohol
containing ethanol can be used if the ethanol con-
tent does not exceed 10%. Gasohol containing
methanol is not recommended by Yamaha be-
cause it can cause damage to the fuel system or
ATV performance problems.
