If there was going to be a pure ethanol fuel you certainly would need to have an ethanol carb
, or injection system. I thought to run a holley carbed small chevy engine on E-85 and there is one place I know in MI (Pro Systems Racing Carburetors
)that will build or modify carbs for such use. They may find a new market in bike carbs. Give them engine specs etc and there is no reason they couldn't map
out what you would need. You might shoot them an email and see just what it would cost to do something like this or if they would even consider it.
IIRC (vaguely) optimal A/F
ratio with E-85 is on the order of 6:1 or 7:1... something like that (those could be alky numbers). This would surely mean some huge jets. One thing cool about a fuel like E-85 is that it is about 105 octane and will easily support a 12.5:1 CR (yeah those high compression pistons would be great) One drawback is the Roadie fuel tank basically becomes a peanut tank due to the amount of fuel required.
