Tim has it spot on. That back end needs to squat to the max, not bottom out, and rebound just enough to offer some suspension compliance in the back half of the track. Get the sag right - 75mm?, and don't over spring it.

Do you have stageable boost? If so, limit boost in first, ramp it up a bit in second, hit it HARD in third and fourth and back off a bit in fifth and a maybe little more in sixth, depending on the trap speed. As the aero drag loads go up more boost is wasted with wheelspin pushing air. You've got to find the sweet spot for every track.

Rickey's shootout bikes were consistently the fastest at around 375 max hp unless there was awesome traction, when we could run up to 425. Any more than that was useless anywhere.

I'm a noob when it comes to proper shock setup. I saw that previous post and said crap, I've only got about 3/4" of sag and 4" total till the rear tire bottoms out. LOL
