The PSI won't fit in the ATC frame without modification. The motor and head aret too tall.

Teaching quads a lesson
you will have problems fitting a bigger bore than a 350 in a atc250r frame and most cylinder heads, the spark plug is in the center and straight up requiring you to cut and move the diagonal frame support. I have a lrd 310 pv and it has more power than most can use. I also have the correct pipe, igntion, carb and some other mods too.
