Wim, Richard, List,

For the record Yamaha makes great pianos.

Now in response to the Richard's comments above, I can establish this:
I have tuned 20 + Yamaha U1s', late '60s' & early '70s' vintage, for easily
15 + years, 2x per year, in a university environment of heavy use and
changing temperatures/humidities.

Allowing for exceptions to the rule, the lost motion has changed enough
between visits to use the leather method tip I mentioned earlier in this
thread.  Before using the leather method tip, I adjusted lost motion for
each key manually by adjusting the capstan dowels.

These particular Yamahas' I mention are susceptable, and this is one
documentation for your file.
