I have seen other posts on this. If I am not mistaken a shim is place between the pin and the drive face. This causes the two ramps to be spread further apart on takeoff allowing the belt to be further into the front pulley lowering the gearing a bit. This should theoretically have a slight drain on top end speed as well. The mod to the rear pulley will increase top speed without affecting takeoff. Though if you did the two together you could in theory gain takeoff and top end speed. Hmmmmmm. New direction maybe.

I'll take your insults as compliments and blame it on your lack of intelligence.
