the Rotax MXZ(800?) snow mobile topend can be modified to fit on a 250R cases. Those come out to be about 400cc and are real rippers from what I've been told. never seen one in person.

I've seen a "polanda" motor, Where a polaris top end was on a 250r lower. I think it also was 400cc. Ran pretty good.
