Hammer butt springs can get into the picture slightly, friction of course. Outside of that you are going to have to look at key weighting and leverage... tho Yamaha should be pretty consistant on those points from piano to piano. You might also check to see (as a long shot) if for some reason the upper action mounts are screwed in equally on both instruments. Not likely... but you never know.
