Catalytic Converter; Fuel Cock - Yamaha Vstar XVS650T 2004 Owner's Manual

knocking (or pinging) occurs, use a
gasoline of a different brand or premi-
um unleaded fuel. Use of unleaded fuel
will extend spark plug life and reduce
maintenance costs.
Gasohol
There are two types of gasohol: gaso-
hol containing ethanol and that contain-
ing methanol. Gasohol containing
ethanol can be used if the ethanol con-
tent does not exceed 10%. Gasohol
containing methanol is not recom-
mended by Yamaha because it can
cause damage to the fuel system or ve-
hicle performance problems.
