cr500 and the infamous aluminum frame?

I want to put a cr500 motor in a cr250 aluminum frame. I have heard a couple of guys have done it. Does anybody know if this is an easy project, better yet have you done it?

a friend an i fitted one to a crf250 frame,had to make a few brackets and a little bit of welding but it turned out good and is a weapon, not sure about fitting to a 250 two stroke frame you would have to take some measurements.

there is only one place to get that kind ofbike. service honda in Indiana is the placeto get a cr500af. unless you are an expertwelder and fabricator you are going towaste a lot of time and money trying toget it done. also a cr500af is for expertrider's only.
