Ok. Glider is right (as usual)
I went from dealer lube, whatever that was, to M1 75/140, to Amsoil severe gear. There was no noticeable diff between any of them really except going from what I think was the Syn3 to the M1. It did quiet down some. I recently went on a trip to Florida and the fine folks at Millers HD in Daytona were kind enuf to turn me onto some of their private stash of the Spectro 6 speed gear lube.
Night and Day Glider. I poured that quart into the Dyna and went for a ride. Apart from the initial drop into first clunk when cold, the shifting bangs have all but gone away. The Spectro is really top notch - good thing I bought 3 quarts.
