Hi gang.

Several of you were getting mighty warm. The problem is related to the 
balance rail pin / hole / position thing. I figured it was pretty easy 
to narrow in on this one. But no one got it 100 % right, so I throw out 
the kicker clue.

If you removed the stack, the keys would fall forward and perhaps about 
a third of the keys (black and white) would fall to only about 8 mm key 
dip. No balance rail pin top was pushing against the back of the key 
button. Bending them forward wasnt a posibility actually as they were 
really too far forward already. The pins were not to tight per se...as 
I'd just sized them to fall slowly ala Yamaha's  method for that. 

When you pressed hard on those keys... you could see the top of the 
balance rail pin just aft of dead center in the window flex forward with 
the pressure on the key front.

Cheers
