    Head Cracks....

    Head experts, do these GS heads have cracking problems? I hadn't heard of it until now.
    This head is from a two valve 750/850.
    Are these cracks a problem? Can they be welded? Ignored? Scrap aluminum??
    Seems like the cracks haven't cracked through the valve seats, so maybe it won't go any further?
    Running out of heads...

    Two more chambers have cracks, this is the worst.

      looks bad to me, but then again your picture is magnified a lot so it may not be that bad in reality 8-[

        Most 2 valve Kawasakis look like that. For a streetbike, I wouldn't worry about it.

          I'd be more worried about the pits in the seats if that's what I'm seeing.

              Nothing a few minutes worth of lapping won't fix.
              It is highly magnified.
