The Rotax 650 is the biggest engine in the world.......exageration.......It's huge
The sprocket is on the wrong side (I think) and you will have to find space for a radiator. |

If i was putting a big motor in a 400ex i would go for a air cooled xr 600 or the 650. _________________ Phil..... |

| What Phil said, or you could put a 450 r motor in it as these 3 have been done before in the States |

I'm assuming your askin because you've got a rotax 650 lying around Spiersy?.... I'd go for an XR650 engine which is marginally smaller than the Rotax.... _________________
