Will my motorcycle engine fit?

1984 Honda Shadow VT500C engine fitting into 1976 Honda MR250 Elsinor. Yay or Nay?

Added (1). Thanks!

Personally I don't think it will. The size of the engine of the 1984 Honda Shadow VT500C is to large to fit into the 1976 Honda MR250 Elsinor. So Nay.

But I don't know really so don't mind me. No (or Nay). Nope Not without major modifications. Not worth it. Stupid swap - the frame suspension & brakes will also need upgrading. A much bigger, heavier more powerful motor in a dirt bike frame bad idea. Chop saw, welder and $$$ you can fit a 350 Chevy V8 into a old Honda 750 frame. Your possible project?- is start with $2000.00 in pocket and a shop with the tools previously mentioned. SO, possible but not worth the time, money and effort for most people. As a engineering class project with some other students? Good lesson in what is possible, what is silly, what did you learn about 6011 welding rod and paperwork required by DMV?
