I just found this from 1 Slowz "the factory crank pulley is 146mm
SO an 88mm pulley would be 146/88 x 7500 x 7.5 = 93324rpm "
So a larger crank pulley appears to make the s.c. spin faster.
A) My setup 90mm pulley w/ stock crank 146 mm pulley -146/90 x 7500 rpm x 7.5 ( SC gear ratio) =91,250 rpms
B) Using a 150mm crank pulley, 90mm s.c pulley 150/90 x 7500 x 7.5 = 93,375 .
This is if my formula is correct???
THINK I'LL DISREGARD THE CRANK PULLEY IDEA.... DON'T EVEN KNOW IF DIFFERENT SIZES ARE AVAILABLE..
