puzzler - not

[Dave Smith]

Ron, I encountered this problem with a disklavier and an extremely picky
customer with an acoustically HARD room.  After working through the swapping
of plungers, etc, I called Yamaha service and they sent me a bag of slightly
oversized plungers.  Solved the clicking problem immediately.  Of course a
couple then were sticky and needed a slight sanding.  :)     This might be
the answer if all else fails.
