Jim, I never heard of it either. But common sense says that when a bunch of new parts are put together, there's going to be some metal shed from parts as they mate. So it's probably a good idea, especially since Ray has that nifty reversed ring and pinion from Subagears or whatever the name is.
It's interesting to me that someone else thought that the Redline didn't give them any better shift action. Thanks for that, Ray.
