i started this thread. i also have run alcohol (straight) in drag bikes and quads (2 stroke) and it works well when tuned properly, BUT when you run it you do shorten engine life. you must drain the fuel system daily, and purge the engine heavily with a lubricant such as wd40 or equivalent to HELP the crank seals, internal carb. componets, etc. from being dried out and eaten up as fast. everyone has their opinions but my experience is that alcohol IS harder on certain engine componets and there is higher fuel consumption with alcohol.
Again, you are talking about methanol, used in race engines because of it's vaporization properties. It also is much, much more corrosive than ethanol.
