I have two exhaust studs that need repair. One was previously repaired at a local shop using a Helicoil and it backed out taking the threads with it. For that one I would like to repair it using a time cert instead of helicoil. The second on the back cylinder is broken off flush. For that one I need access to a Jims exhaust stud drill plate. To complete these repairs I will need the Time Cert kit and the Jims exhaust stud drill plate. These tools are very expensive for a one time repair. Does anyone have these tools that I could rent or know of a shop in North Jersey that could do the repair at a reasonable rate? | ||

You could try the one from here http://www.americansportbike.com/shoponline/ccp0-p rodshow/16029.html As for the helicoil, I would get it to a proper shop and have the stud bolt sleeved to the head. I have even seen a really nice bit of work where they channeled out material to remove stud and added material, with a re-tap and install of new stud into fresh tapped stud hole. Do your homework and find a good bike shop. I am just lucky and do trade work for a local race bike builder that hooks me up fat!! Oh also i do all my own work. This bike has never seen a dealer, Since i have owned it or that o know of! I took in the whole bike and it was done on the bike While i waited. Now if i were you i would have them drill it a little and weld a rod into the stud, a (square) one and use a crescent wrench to turn it out, This is the easiest and quickest way to get a stud out. It heats the head and expands the aluminum, Even a little pre-heating wouldn't hurt as well. This is my favorite method. Dont use any easy out or anything that could snap off inside the drilled out bolt. IT CAN BE NIGHTMARE IF YOU BREAK ANY EASY OUT IN THERE! Now this will only work if you can get a drill to it without a head tear down! | ||

I heard that some have tack welded a nut to the remnant of the stud too. Another thing to try is reverse direction drill bits. I've been very lucky with mine and the worst that ever happened to mine was having a nut fall off and once having the stud back out of the head in one piece. I am not a great fan of the interference nuts that H-D uses. I prefer normal nuts and the rust acts as a great lock-tight  |
