I have a hex bolt jammed in the bottom of my Yamaha Virago's lower fork tube. The head of the bolt is countersunk into the end of the tube, so I can't get a vice grip around it to twist.
I have tried damn near everything to get it out: I soaked the part in WD 40 for two nights straight. I tapped on the head with a drift to try and loosen the threads. I tried an impact driver, it unscrewed a quarter turn then stopped, and ended up gouging up the head, distorting it and possibly expanding it further into the part. As a last resort I tried torching the thing and it did nothing.
I really don't want to drill it out. And I'd rather not pay the shop to do it. Any suggestions?

You need to get something like screw out

They also have bolt out if there's any head left to be grabbed.

What I've done is to drill a small pilot hole and use the screw out. By the way, torching only helps with nuts (fits on the outside). It helps by expending the nut (away from the bolt). If you try to torch a bolt or screw, it only expends it and make it tighter against the hole.
Good Luck.

Its sounds like a really problem but. I had the same problems. This will work, Go to home depot get drill mil kit 29.99 an use it with one of the diamond tip rubier. grind the head down so you can pull off the part. I broke off a tap inside a alumina head and i wanted to die. OK ; I get the broken tap out. The tap metal was to hard for drill. Back to you The rubier have a gray rough finish on them. Your bolt is not that hard metal, grind the head off and pull the part, now if can use vise grabs and start slow turning stud back in an then out so you can save the threads. If not, done the some thing but try not to take to much out. You will start to see the threads. you will need to re-tap the threads after. It sound like a lot but its not 10or15 minis head bolt.

There are one of 2 way to get that thing out. Either you can use a 1/2 inch impact gun....and that usually works if you dont destroy the bolt first. Or you can drill it out. Which is very much a pain in the tail, but thats about all you can do. Judging by the way you described handling the frozen bolt in the first place I would recommend having a shop take care of this for you before you make it worse.

When they're stuck that bad then drilling is about the only thing left, but you don't want to do it with hand tools. Take it to a machine shop. They can use a drill press and a left hand dril lbit. Yes there are left hand drill bits and they usually work to remove stuck bolts. However, you need a way to hold it dead center, which requires a machine shop setup.

In the Uk they have things called EZ-out (easy out) which are reverse threaded, tapered screws (similar to a thread tap), you drill a hole in the centre of your bolt and wind this in with a wrench. When it binds, hopefully, the force turning it in overcomes the stubbornness of the bolt.
This does not always happen and you have to buy good quality EZ-outs.
The best bet is prob to take it to a small engineering outlet who will either remove it or drill it out.
If they have to drill it out they can reinstate you original thread size usind thread inserts (called Helicoils).
I assume that you are trying to remove the stanchion of the fork (chrome) from the slider (alloy). Be careful because Yamaha use a bush system that will require you to slide the stanchion quite hard (like a slide hammer) in order to remove the fork seal (make sure the circlip is out first.
The fork seal is then not easy to replace because the stanchion has to be in place at the time.
Hope that helps

you may have to drill it out..
you said you could get an impact driver on it but gouged the head... You can get a set of sockets ... that grip rounded heads for about $20-30 sears have them..
they do work...

at this point, you have two choices, try drilling it with a drill bit just small enough to miss the threads and using an E-Z out to remove it, or drilling and cutting or chipping it out a small piece at a time. Other than that, a machine shop should be able to do it for you

Try some penetrating oil. Not wd 40. They sell it at hardware stores or auto parts stores. Just ask the guy behind the counter and they'll be able to direct you to something to help you. I hope you get the bugger out.

other than soaking it ,you have done about everything anyone can do ,if soaking it doesn't eventually get it out it may have to go to a shop,my dirt bike did this ,and i finally too it to the shop and said fix it,it may come loose after another good soaking,i still don't know how they got mine out ,because it was rounded and had no grip left on it,good luck with it.
