    exhaust bolts cross threaded.

    the p/o of the 750L has cross threaded each and every exhaust bolt there is . not to mention that he broke one of them off .

    anyone have an idea as to how i can get these fixed? best way to get it re-threaded if its possible. i know its gonna take some work, but i should be able to get the broken one out.

    Welcome to my world....
    Cross threading can be fixed with a tap (M8 X 1.25).
    Soak the broken one with PB Blaster,and either vise grips or weld a nut to it. DO NOT GET OVERZEALOUS AND BREAK A TAP OR EXTRACTOR OFF IN THE HOLES. THEN YOU WILL BE LOOKING FOR A NEW HEAD.

    ask me how I know....

        Best bet on getting the broken one out would be running the bike and trying with it hot, but I bet the pipe is already off isn't it....

          No doubt you'll be fine on your head, just be careful. I had to replace mine because (you think your PO was bad) I had...
          4 holes already with inserts in them
          1 hole with a broken bolt below the surface
          1 hole that looked to be drilled for an insert, but with no insert in it
          2 holes that needed to be tapped.

          In the process of trying to fix that mess, the hole drilled, but with no insert had been drilled too deep by the PO and when putting in the insert it broke through the head and now leaks oil. I managed to get a drilled hole in the bolt broken below the surface and then promptly broke an extractor off in it. At this point, I started shopping for a new head.
