What about burning E85 in 1964 Honda and 1983 Yahama motorcycles?
E85 is (from Wikipedia) fuel made from 15% regular gasoline and 85% Ethanol. Ethanol is an alcohol made from organic materials like sugar, corn, and brewery waste. Drink a beer and stop global warming! But seriously, Ethanol can be a viable alternative to oil which is hard to extract from the earth and located in hostile environments.
The real danger to running ethanol in your engine is the damage it may cause to magnesium, aluminum, and rubber parts in the fuel system. E85, or Flex Fuel engines have rubber conditioned to transport or store E85 and stainless steel that does not corrode when exposed to alcohol.
If you are really serious about converting your engine over to accept E85, the process shouldn’t be hard, as long as they are four strokes. A trip to your local auto parts store or favorite internet shop should provide you with what you need. Also read Roger Lippman’s excerpt about converting an old VW engine. I hope this helps.
