    650sx overheated

    My 650sx overheated first time out after a top end rebuild water intake line came fell off and I didn't realize got really hot and died and swam it back it got so hot the red paint on the head turned brown any speculation of what could be damaged ill probably tear into it this weekend. But I'm feeling defeated after i just spent a ton of money rebuilding it.

    I would pull the head and check it for flatness. The stock red colored heads have a tendency to warp. Other than that it's probably ok.

    Pulled the head off gasket definitely failed and head warped ill get it skimmed and throw a new gasket at it. Im just worried about the crank bearings. Should I be?

    The head took the brunt of the heat. If you put the head back on and the compression is still good then it's OK. The rings will fail/collapse with heat before it hurts a ball or needle bearing.
