I know a guy whos got those two bikes for sale. The 90 KX250 for 1800 and the 93 KX250 for 2000. The 90 doesnt really need anything except a top end and maybe the shock seals. The 93 needs fork seals, shock seals, cables, and alot of general cleaning up and everything. Both run good so i'm just wondering how much of a trade off 3 years is really going to be. I know the 93 got an updated (and much more complicated) powervalve design that im a bit wary of with all the extra parts. So whats better, the little bit older bike that needs less work or the bit newer bike that needs more work. The 93 was actually dressed up to look like a ktm and was in the fantastic 4 movie.
