Notes: This engine is very fast, loads of fun, and works excellent for MX. It looks totally stock and really comes on (40+ HP)with porting, cams, and a Jardine RT-5 exhaust system. It revs super fast and almost hits like a 250 2-stroke, but with more bottom. It is good choice for vet riders that long for the old 2-stroke hit.
