One difference between some older and newer Yamaha is the type of pivot screws. They used to have headless pivot screws and I think newer student models changed to head screws... I'm pretty sure.
The advantage of the former is it's easier to adjust, but sometimes the friction is long gone and you need to secure them in some way. The advantage of the latter is... they don't usually have that problem, but if the keys are loose it's a bit trickier to adjust, can require special tools, etc. Luckily even with a bit of play they usually play fine.
