    Well, I snapped off part of the right front cylinder head exhaust stud and it started backing out when removing my front head pipe:

    I have sprayed the stud with PB Blaster and will double nut it and back it out.

    A couple of questions:
    • If it will not come out, can I leave it in and use it (assuming there is enough stud left)?
    • When installing a new bolt, do I put anything on the part that goes into the cylinder head?
    • After researching repairing studs, it seems the threads should be lubricated with oil before torquing the nuts. Does anyone do this?

    If you can get the stud out I would replace it and use antisieze on the threads going into the head no oil on the nut torque it dry:s

    Thanks Jack. I safely removed the stud using the 5/16" socket from this set and PB Blaster.

    This is the stud next to the new stud I will insert with a double nut.

    Any suggestions for keeping the stud straight doing install? Should I use the flange to help?

    Thanks

    Thanks Jack. The install went fine and the exhaust is back on. I will ride tomorrow (I still have to put the outer and inner primary back on from what I thought was a transmission issue that may turn out to be just a loose belt issue.)

    Just got back from a 1700 mi RT ride to North Conway, NH.

    No issues with exhaust. (My transmission issue turned ot to be a loose belt.)
