How about the overall height from key bottom to capstan top on one key to see if the measurement changed during the time between adjustments? No? Did anyone look at and measure anything at all other than dealing with the symptom of lost motion changing? Heck, I've cleared up more than a couple of really embarrassing mysteries for myself when I finally quit pondering helplessly and actually went looking for causes. It always makes me wonder what other painfully obvious things I'm baffled by on a daily basis. Hello, hello? Ron N >> OK, smarty pants, :) Even if I did do all the measuring, (which I didn't), what if I did find movement in the keybed. Why is the keybed moving so much as to cause lost motion? ( I had to turn each capstan about 1/2 a turn.) Was it the moisture in the back rail cloth? Did the back rail flatten out? I don't seem to have this problem with other pianos. Why is it happening on Yamaha studios? I thought Yamaha's were supposed to be better than the average piano, which does not have this problem? Wim
