Most guy's that run the 10's in Prostar (3" off the ground and stock wheelbase) run 15/39. I have never ridden a lengthened bike, but Norm Jackson posted that he runs 15/42 on his bike that is close to 59".

Im 140lbs and have seen 9.61 with a 15/39, lowered and strapped set-up......everything else stock down to the airfilter. I don't think I would go over a 41 if you going to use the same set-up on the street. the 15 will cut your top speed down into the 160's.....that's what it did to mine and that was with the 39 on the rear.

Also, I don't know how your cutting 1.52 60's and still not in the 9's.....that doesn't make any sense to me. My 9.61 was on a 1.55.

If you are getting 1.52 60' times you should be able to go 4.0 330's and even with stock horsepower i would guess 9.50's.

im 200 lbs. i cant understand it either.. i just purchased an air shifter because the prob might be my shifting. i have cut in the 1.50s more than one time. im thinking of trying a 41 tooth. when i do ride on the street, im not real big on trying my top end out too much. isnt a stock chain a 525? does anyone have a 41 tooth rear????
