The original clutch set up worked fine and they shifted fine too. They just got rattley/noisy with some miles. The new set up is really smooth and quiet on mine but I also did some under-cutting of gears too at the same time but lets not go there for our discussion. I have put 130 easy break-in miles only and have other problems engine-wise so I parked it.
My #2 has an old stock set up in it and it has NO miles. I want to see how it does and then decide to do the field fix upgrade.
