Mine is usually about 5000RPM until the light changes, then I nail it at the same time I'm letting out the clutch. By the way, Laurent, the first Wednesday night drags this season at Sears Point are on April 3rd. I plan to be there.
I just watched some video, and, for me, I slip the clutch between 60'-100' out..... It "feels" like a long way out there. The longer you do it, generally the better chance you have of counter-acting the power wheelie.
Good run Azsportbiker......

I really suck at launching my 929 too. I think my biggest problem is not being able to keep the front wheel on the ground. So far, I've only been able to manage 60' times in the low 1.90's and ET's in the 11.0's.
