I bought a Cat 250X some years back had the original tecumseh HS4 but locked up. I put a 212 Predator on it for a "short' TIME and was going along about 20 MPh and dial in a little throttle and up and over it went. Happened so fast . no time to react. those bikes are TOOOO small for a 212. too wide and tall for the little frame. it fit but the tank was close on the upper rail .
