I have dune ported stock cylinders, and I'm guessing 20cc domes, vf4's, stock carbs, pc pipes, lightend fly wheel, +4 timing plate 14-41 gearing 20" tires and Hella rich on the jets. It is a blast to ride, got pretty decent low end, but it's still a banshee. I am going to have Cam do a promod for me one day and a 4mill crank.
