I would start leaving around 8k and no more than 10k. Slip the clutch out. you should be 1 and 1 with the clutch and throttle.

I normally run between 8 and 10 psi depending on how good the track is hooking up. Street tire pressure will definity make you sit and spin. What kind of tire are you running?

I run a 190 Shingko (I believe the stock tire for my bike is a 160 or 170), at 28 psi on the street, and that pressure seems to work very well at the track too. Im finding that the higher I launch, the better my 60'' gets. Looking forward to getting a strap to help keep the front end down. With more practice, I could see leaving at 13 or 13,500, at the track, a Pro AMA rider said thats what I should be leaving at anyway. Time will tell.....
