I have a question regarding the cush-drive ...after removing my wheel from the bike i took the sprocket assembly off and found that some of the rubber pieces had separated themselves from each other...is this ok? or do i need to buy new ones?

Even if they look okay, they should be replaced around 50K, or so. At that point, they've had enough compression to be permanently deformed, even if they otherwise look okay.

Thanks :)

I understand that Honda upgraded the rubber at some point but I don't know what year.
