Confirming fix Got the bike back in the rocks this weekend and ran flawless. Changing the PV bearings fixed the problem. Thanks again for all the feedback and suggestions.

New PV bearings New bearings arrived and upon disassembly discovered that the old bearings that seemed to move fine over the range of travel in the cylinder were actually pretty bad. They felt like a set of chinese wheel bearings after a month of riding. I popped one of the sideplates off and...
