i dont think it will work everything has to line up perfect not just the bolts but, give it a try and let us know wheater it is easy or not worth it

Sreiously, it can be done. There was an article in one of my old mags about a 400xx they called it, with this same set-up on it. It was a pro-am MX'er back in the day. Not sure if it was a 250x or a 300ex, but it shouldn't matter. I got a pic of it but can't post any right now I guess.

Most likely TC or Sparks. They were the pro am motor builders.
