* Never use fuel that contains 10% or higher Ethanol or alcohol additives in a carbureted motorcycle and do not store vehicle more than 30 days with ANY fuel containing any Ethanol. Prolonged use of 5-10% Ethanol enhanced fuels will greatly shorten the life of any diaphragm or seal. Avoid using fuel system cleaners such as Seafoam or intake cleaners unless replacing diaphragms/seals after use. Never use E75, E85, Flex-Fuel, or any fuel that contains greater than 10% Ethanol or other additives.
