Errrrrr, am not sure but as far as I know the 86 KX doesn't have a powervalve (KIPS system) and it uses a borable liner instead of the plated aluminium one that the newer ones have.

Not sure about the rest but you should be able to pick up some of it from looking at aftermarked catalogues and if the piston has the same part number it will be the same, check out crank bearings,conrods and so on.

I have too old -86 KX.
86 have KIPS only extra exhaust ports. Not in main exhaust port, like newer. I think that this is main difference. 86 have already electrofusion cylinder.
Look here difference between years: http://www.buykawasaki.com/Default.asp?
