I have had this dirtbike for a number of years. Its a 89 rmx250 according to the numbers on the frame. What would i need to do to convert it to ethanol/alcohol? Thanx

Lots of pistons, huge main jets, skinny jet needles and above all patience. if you want it to run anywhere near as good as a crisp one will on gasoline, you will likely find that you need to do some head work to get the compression ratio up. then get some premix oil that works with methanol.

Is that even possible?

really possible. it was a popular thing to do with minisprints. it is not near as easy as filling it up and kicking a few extra times. there is an honest 50hp to be had though. there is a "bill" for it though.
