Lightened primary gears!

Probably more bang for the buck than anything you can do for the Z, our lightened primary gears shed 2lbs of the rotational mass of the stock unit, for huge increases in acceleration and throttle response.

After installing the primary gear and HD clutch, it seems the clutch isn’t disengaging, took it back apart and noticed the primary gear will not move at all. The shaft the clutch basketbsits on does move freely by the primary gear shaft will not. Is this my culprit? If so how do I remedy this?
