The power to weight ratio of a 2 stroke is hard to beat. I've done some numbers and on the low end I'll be around 200hp and the high end will be 250hp. It will likely be a 500lb bike though. I'm shooting for a gearing combo that will yield 80-85mph. I suspect that will be very competive with a 12mil.
Who knows what guys really run in their bikes, but with my stock R1 I beat guys claiming to have 10mils and been beaten by guys claiming to have 10mils, so who knows.
The motor is in the frame now and I'm working on the turbo plenum as we speak. I would like to have it done for the night drags.
