Scott,
I was in macon this past weekend, my motor is a duncan national kit, I have the roll design front end, and a -1 laeger swingarm. I ran 16/41 and had no problem clearing the man killer on the back straight. 110 foot down hill triple, come out the berm nailed in third, clicked four and left the face with the pipes screaming. I only over shot the landing once by about two feet, but thank god for long travel. I live in S Carolina, what tracks are you racing at, is it mx or tt or flat track. I want to go race a few flat tracks in NC, I've personally never race one. I've run a few tt's in kentucky but everything else is atva national tracks.
