Dual port engine, good start! I love the look of those things, but I think it would freak me out to ride, my only memories of them are when I was a kid we took a lot of long distance car trips for vacation, and would often see big groups of harlys out on the interstate, there were always a few of these in the pack. I can't IMAGINE the handling, but can't wait to see what you do with this, I don't care if it takes yrs! :)
