anyone have any idea how to make this thing shift??? I got my gears from clearmont today (thanks bro, super fast shipping) put it together, so far gears are good but just cant get it to shift correct, its either 2 soon or 2 late. or stays in second or stays in first. i understand how it works, the center set screw hold the piece in place and the outside screw adjusts when the little arm comes out. Just doesnt wanna work. any ideas??
