    Should cylinder head on a 787 RFI look a little melted?

    I'm thinking of buying a 1999 GTX RFI. It looks like it's in good shape, but the corner of the cylinder head (and the exhaust for that matter) looks like it was melted. In the attached images, I'm talking about the upper right corner of the cylinder head (and on the upper part of the exhaust in the pictures). Is this damaged goods or do the cylinder head castings come out of the factory looking like that sometimes? I looked at some other pictures of 787 engines and none seemed to look melted. Any help would be greatly appreciated.

    Looks OK to me. I think they all kind of look like that. You'd be able to tell if it was melted. Sometimes if the intake gets clogged, the rider will not clean it out and the motor will start to overheat. The paint on the exhaust pipe will actually brown. That looks (from the pics) to be more of a corrosion issue. I would say worst case, the gasket may leak and need to be replaced (and surfaces cleaned). From the dealer a gasket is about $12. Hope this helps!

    You are talking about the area within the red rectangle correct?
