okay so i'm rebuilding a 250r right now and the engine is completely apart because i'm getting newer internal parts well during the process of searching for newer parts i've noticed that some say like 85-86 or 87-89 etc.

what are some of the major differences that i should watch for when rebuilding my motor? i'm talking top-end and bottom.
