John, I just went through that this summer and saw the same thing you did. Nothing. On top of that I cleaned the right side axle spines out of the spool on the starting line 1st round at the Mid Souths at Memphis. Only good light I've had all year too. Byron Latino didn't mind it too much.
When I tore it down, it also had a tight spot when turning it through, the ring gear flange had developed .007" run-out. It was straight when installed. Don't need any more of that crap.
