So I've got a bit of a dilemma... I'm building a custom bike from mostly '68 ct90 parts. I want to change the gearing to be more like a C70 passport/cub, since I'm using a ct70 3 speed motor. However, the drive hub only accepts larger sprockets. I ordered a 36T sprocket thinking they're all the same... wrong-o. The blot pattern on the ct90's hub is much wider. So does anyone know if a hub from a c70 (or other small honda) will work with the ct90 wheel?
