Broken Bolt

Was working on the bike and noticed that lower left tank bolt had broken off. Its 6x40 bolt that holds the tank in place near the seat. I tried traditional methods of drilling a smaller hole inside the piece of the bolt that is stuck, but it won't come out. With other 3 bolts in place the tank not going anywhere, but I am worried if its safe to ride like that and also what can I do to get it out?

I would drill it out, then tap it and put another bolt back in.

If you can grab the head with vise grips, you should be able to back it out.

I tried... drilled a small hole in the center of the bolt. Tried to screw in the bolt extractor, but that thing broke off half way in, so now I am back to square one. I am afraid to drill with the larger drill bit and hit the wall, mess up the tread and end up with even bigger problem.

Don't worry about the thread, see if you can get the extractor out with a pair of pliers or something then drill the hole out larger and helicoil it. Don't bother trying to drill with the extractor still in there though cause there is almost no way that will work.

And you are perfectly safe to ride on it.
