Hey Preddy, Aj told me the other bike had Venom porting and a Venom 12.5:1 piston, I got no info on cam or other goodies. Let's call it how it is, Aj's bike is NOT a Kenz built bike, it has a Kenz head on it that he bought from an RF member and a Racer's Edge 14:1 piston, x2, Barkers, etc. This isn't really a Kenz vs. Venom deal if you ask me, it's a Kenz head vs a venom head. That being said, a cam and compression can easily make the difference. This isn't exactly an apples to apples race here
