I've never ridden a 650 vertical twin. I understand they're around 40 horses. That "jack drive" that Fairless installed to handle the huge rear tire cost 10 horses. Do the math, that bike had to be a bit sluggish.
The new 790cc power plant in a hardtail frame (3.5" stretch, standard rake)with a standard length springer front end (low profile with a tight front end)would be ideal.... I'll let you know when I'm done.
