83-85 200x top end will fit on the 185, 185s, 200, 200e, 200es, 200m, 200s, ect.

It will fit right on like howdy said, and you will also get a decent performance boost if your using the 200x cam. The only difference I can think of is that the 200x head does't have any compression release lever (i dont think) but you don't need that.

Yes, as stated before the heads will swap out with no problem. In fact if you want you could put a 86-87 125m head ( will need a 185-200 cam ) on the 200x. I actually have a 88 TRX125 ( same motor as a 86-87 125m ) and it has a ATC200 head on it. It did increase power. ;)

....okay hold on now, I need the details of this one. Cause methinks a 125m with a 200x head, slapped into a 70 would make one helluva little ride!
