I had an exhaust leak and when I went to tighten it up, I found that I too have had an exhaust stud break. As luck would have it, it was on the rear cylinder so I had to get access. The job is not exactly hard, it's just a lot of work and time. I chose to separate the frame from the engine/swingarm because I did not think that tilting the motor would get me enough work space. I have a m/c lift so that helped and an engine cherry picker came in real handy. I probably didn't need to remove the tail but I'm glad I did just to get extra room to work. I did buy the Jims Tool to drill the stud. Best money I've spent in a long time. After drilling the stud, I looked up in the hole and really couldn't see the threads. The "shell" of the stud was still there. I picked at it with a dental pick and then started a tap in by hand and it pulled loose the first thread. I was able to grab that first thread with pliers and pull out the thread just like I was pulling a heli coil out of a hole. There was a little bit of stud left in the bottom of the hole and when I ran a tap down in the hole to clean up the head threads, the tap grabbed the last bit of stud and brought it right out! Among the contributing factors to this was lack of attention to the exhaust mounting bolts at the head and a lost bolt (gone) from the front muffler mount. I'm sure that put undo stress on the whole system. -Hemicbx |
