Yeah! A good choice, I think. Well, as I said, my sleeve always looks dry and burnt when I take things apart even if it's only been a couple of months. And, of course it isn't sliding well in that condition. I have learned to clean it well and lube lightly every time I have it apart. I only ride short hops, never more than 20 miles or so at a time and never sustain high speeds. So, yes, I agree it's some sort of flaw in the design.
Hey, on another note but still related to variator: You know those three slide pieces that look like a U or V that the two pulley halves slide on? My Dr. P ones broke! It wasn't visible from just looking at them but upon opening up the variator I found bits of them had broken off the back sides and found the bits under the actual sliders down in the ramps.
My Dr. P sliders themselves are still ok. I put the stock slide pieces back in. I would have to recommend not using those Dr. P slide pieces.
