You have to be set up for each one differently, they are not interchangeable. You could run E85 on a methanol bike, but it will run like dog shit. You CANNOT run methanol on an E85 bike, it will be really lean and melt you down. The E85 is not very consistent from pump to pump, so most people don't run it. Its a pain in the butt. Methanol is the way to go.
