Mark Vs Stud = FAIL! 2 EX-500 Run
DAMMIT I hate stuck studs. Well I just finished my apt complex engine swap on my motorcycle. Damn thing has a broken exhaust stud... can't get it out. I tried everything I have... which isn't much.
Anyone got any bright ideas? I think it's too loud for the track with the exhaust leak... not to mention the MUZZY is shot to hell. It's louder than my SV with glasspacks.
On the up side, I have two running EX-500's, one is definitely a track only bike.

Heat it with a cheapo butane torch and spray it down with PB Blaster. Repeat a few times. Let it fully cool. Then tap center of stud with a punch and hammer. This gives you a spot to center your drill bit on and helps to break the stud loose. Then drill with a small left hand bit. Drill with progressively larger left hand bits till it's close to the inside diamater of the threads, then bury the bit such that the bit hangs in the stud and screws it out.
Or break off an Easy-Out in it. Then it's impossible to drill because the easy out is harder than your drill bit or any other material known to man. (It's rumored an Easy-Out is harder than diamond...)

Have you tried one of these? I have heard that they work well.

Is there enough room to make 2 flat surfaces and use some vice-grips as tight as you can ******* get them? Like hurts your hand and takes both hands to clamp it down? That usually works for me.
If you can't do that and its like snapped off inside of the motor, what about drilling it with a smaller size and using an extractor? http://www.northerntool.com/webapp/w...4674_200264674
Those have actually worked decently for me in the past, just need to make sure you have it far enough in to actually grip on the rest of the stud and then apply force straight on it while turning it and keeping it perfectly straight. I'm pretty sure it is key to keep it straight so it actually grips in multiple spots and extracts.

Would like to see a picture. Grinding/filing 2 opposing surfaces flat and grabbing them with a super tight vice grip has worked for me in the past.
<edit> uhhm, yeah the same thing he just said. whoops

I can get a vice-grip on it really tight, and I thought that was gonna get the job done, but that bitch is stuck in there tight. So I am off to go get a torch and see if I can make my luck change. If not, I am gonna try a machine shop and get them to weld a nut on the damn thing and see if it will twist out.

Yup, we had to weld a bolt to a locking lug nut on my car, that I had no key for. So been there too.
It's important to get atleast one flat edge on the stud to get the vice to really bite. Heat can work here too.

I had 2 studs heat welded on the exhaust side of the Kohler twin that I rebuilt. I tried the PB blaster to no avail. Then the HW store guy told me to heat the area around it with one of those mini-torches, and press an ice cube on the stud while it was hot. It popped, and twisted right out.

Well when you grind the teeth off your vice grips, it's time to call it a day. I k-balled a bolt off my SV1000 and managed to quell the exhaust leak. Sounds almost decent now.
So here is the finished product thus far, $500 invested in this bike total I think. It has an after market suspension, flat sliders, rearset with motoGP shift pattern, and the Muzzy exhaust. Not too bad, all said, and it came with spare rims and tires.
