Probably in the High 30's, low 40's. More if it is built right, and properly tuned.

I would say high 40's at the peak, about 38 in normal conditions, this is at the crank not rear wheels. they made 38 stock(crank) pipe will add a few and the combo of mods would add about 10 or so. but real wolrd power would be about mid to loww 40's at the top

Depends on the porting, coolhead dome size, and other variables. I'd say you are probably between 35 and 50.
