Disklavier

Bill, what affects feel (light or heavy) of action? My 1997 U1 DKV action feels much heavier than the 2001 U1 DKV. Could it just be stiffer if not played as much?
I assume this cannot be adjusted.

My tech put lead weights on the backs of the keys on my old 1979 acoustic U1 to make the action heavier - it was much improved - but that seems a bad idea with a DKV.

Also, the keys actually seemed smaller! Has Yamaha changed their design that much? My pianos are from 1979 and (DKV)1997, this DKV is from 2001.
