not many changes over the years I have an 01 and my buddy's is an 87
his motor is black, mine is silver. His has a paper top end gasket, mine has a steel one. His sproket is held on by a locknut and washer, mine is a circlip. He has a two way powervalve, mine has a three stage.
I'm not sure of the cuttoff years but I think it's from 86-87
88-95 and 95 to 03 changes were made....
somebody correct me if I'm wrong
If all else fails use the numbers off the engine

These are all    the features I can think of that this 87 has.

KIPS logo on left side of cylinder is glued on, the kicker is a flange head bolt ( not an allen bolt )
A mikuni vm carb, paper top end gasket, no locator or dowel pin for head and cylinder. no third exhaust valve over the exhaust port. you can tell by removing the pipe and looking in.
