Yama-help, s.v.p.!

[Ed Sutton]

Wow!
You could wait until the clicks stop, clamp down the key tails so the keys
don't move, then lift and lower the hammers and see if the clicks recur.  If
not, that points to Ron's balance hole squeaks.  If yes, probably whips or
hammers.

Does it happen if you just lift and lower one hammer?  Could it have
anything to do with the stack or keyframe flexing?
Is the stack screwed on tight, the rails tight, etc.?

You could lower the rep lever until the hammer is all on the jack, and raise
the lever until it's all on the rep lever, and see if that changes anything.
Maybe the knuckle just barely pushes the jack off its rest, then it slips
back, making a little click in the jack spring hole?
