Can you run E85 gas in a Harley motorcycle?

I ran a 91 s10 on it for a while, and the only problem I had was cold start rough idle. It had better throttle response, but it seemed like the gas mileage went down. It would be worth it if the e85 price is 50 cents cheeper than gas.

Updated answer,

I am not suggesting that you should give up on running your Harley, but why bother with fuel when the C-1 MOTORcycle built by Lit Motors is coming on line.

120mph and all electric.---- Safety features alone should make it a no - brainier---.
