Should be a simple swap...from what I've learned about these bikes (still looking for the odd part to get my own '77 DT250 licenced for the street).

Good luck with that...should make a nice dirt-rocket, and would still be registered as a 250...cheaper insurance, at least in these parts...(oops, was that my indoor voice?)
