- Doing this for the first time, so forgive the basic question... The Goodparts instructions for the GP2 say to advance a few degrees for low end torque, which is what I want to do. I see how the sproc

- John--You are correct in which way to move the cam. I wouldn't "advance" the timing too much tho. I'd say 4 deg. to be max without compromising other features of the cam. (Personally, I'd set it as c

- You are corrected. "Advanced" timing means the valves open earlier relative to the crank position. I don't recall which way the crank and cam turn, so I am taking your word for it that the crank and

- I would second Dick's advice here John. Since the GP2 is already more of a low-end torque kind of cam, I would set it up with standard timing. The GP3 is tuned more for high-end, so this one would pr

- Regarding the cam timing... both the GP2 and GP3 have 110 degree lobe centers, so advancing the cam by 1/2 tooth would move the intake lobe center to 106-ish which is where a lot of hi-po cams are.
