Yep, some guy did make a 1/8th scale model of a Knucklehead. Yes it does run. I think weird stuff like this finds me to be honest. I searched for knuckleheads and I got ’em. Just a lot smaller than what I was looking for. The guys name is Jerry Kieffer, and if you click on the pic it should link you to a model site, where you can see more pic’s of the 1/8th scale bike he’s working on. Different yes, waste of time? I’ll let you decide.
