I installed a Rivera Pro Clutch in my 09 FLHX. Nothing but problems. Hard to pull in, rough feel and slips like crazy. I returned it to rivera and they sent it back with new friction plates. Still hard to pull in, rough and I have no clutch engagement. This happened before and I played with the adjustment and it engaged, but slipped like crazy. Anybody else had this experience? What could be wrong?

Thanks!!!!!!!!!!!!!!!!!
