Well it looks like I managed to cook the motor in my xr650rr supermoto. I'm going to ship the engine off to Rob Barnum to work some go-fast magic on it. My dilemma is this... I'll need to figure out how to flush the frame to make sure there are no metallic particles hiding in there when I put the fresh motor in. I cannot just stick a garden hose in one end and let it go, EPA would frown on that. I was thinking perhaps a local radiator shop would be able to do it. Any one else had to do this yet?
