Has anybody ever put a 350X engine into an 83 ATC 250R frame? I ask this cause I have both a spare frame and engine. Would it be very hard to do? I have a welder and can use it very well I was just wondering if any one has done it and how hard it was to do.

 

I saw a local guy put an old 700 4-cyl! streetbike motor in an old suzuki 250 quadracer frame.. if he can do that I would imagine that you can also.
