Sorry if this is the wrong place to be asking but it seems the most logical place for me to find advice. I am thinking of putting a 4 stroke 250cc engine from a 1982 Suzuki SP250 into a 1980 KDX 250 bike. Has anyone done anything similar or have any thoughts (other than complaints of blasphemy lol) about this idea?

That sounds just downright WRONG.
(But what do I know?)

Go for it! I'm game for all freaky cross breeds. However, I know absolutely nothing about either of the bikes you listed. But how hard can it be??
Major considerations include swingarm pivot/engine case compatibility, sprocket alignment, frame clearance for taller head of the 4 stroke, and the airbox. Things like engine mounts are easy. Doing the pipe will be a little harder. Getting sprockets, airbox, and swingarm to align and work are the tough parts. Start there. Then show us pics of the progress!
