SON OF A.....

[Bullxb12r]

So, I started out today going to work to help with a swap meet at our shop. After much adjusting and tinkering around with the new-to-us Dyno, it was finally time to put a bike up on her (just to make sure our time and hard work didn't go to waste).

After we made a couple of pulls on the very stock motor, I learned she's not as ballsy as I thought, but still a respectable 87 HP and 78 Ft.Lb. of torque.
So we unstrap her and go back to work. (Now on to the reason for the title). At the end of the day I left work. I pull up to a stoplight about 2 miles away from the house and hear a jingle coming from my motor. I pull off the side of the road and start looking around and here's what I find.

Left with no other option, I limp her the rest of the way home. By the time I get there, the other one shears off too. I suppose I will be learning how to do an engine rotation in the very near future.

Damn the bad luck. Is there enough stud left to soak it with kroil for a couple days or right off the getgo you have to drill?

Ick.

For headers, follow the guide in diy section.

Try an impact driver to remove the stud after you double nut it.

Those numbers at the wheels are not too bad Sorry about the rest of the story

Be careful what you do it is fairly easy to remove the head but take it to a machine shop. I tried to ezout mine and now Im stuck and waiting my new head to arrive.

Thanks guys. The shop I work at has a machine shop in it so no matter what, it's not that big of a deal. I was more venting than anything. Just such a pain in the ass. The upper one will have to be drilled. Pretty sure the lower one has enough left on it to double nut.

you got a set of those bolt pullers? the ones where you drill a hole and then you drill in something similar to a reverse screw to pull it out.

That would be an ezyout , these things are brittle and while they can work well they are also made of a material that is harder than any drill bit so if it breaks you are in big do do as Buell Dude has obviously found out.

No, ez-outs don't usually work on exhaust studs. the heat sets them in pretty good. I have the tool that lines up the bolt for drilling. Gonna try the left handed drill bit just in case, but I seriously doubt it will back it out. So far this month I have drilled 4 different heads because of studs breaking. I have only had 1 back out with the bit. We'll see Saturday if I can get 2 to work. There's only 4200 miles on the bike so the studs may not be siezed in there too bad.

If it is sticking out enough just get a single nut threaded onto it and weld the nut to the stud... the heat from the weld will transfer into the aluminum head and you should be able to use the nut you welded onto the broken stud to back it out.
