The bike already had an ear shave from the previous owner, but it was never marbled or coastered. I bought some coasters online, should be here in the next 3 days. Had some extra time so I decided to remove the valve lines. 3 bolts came out with no problem, then, the 4th bolt (right side, lower bolt) decided that it was just going to snap. Cool! There’s about 1/4” in. Luckily it didn’t snap flush like I’ve read some people have had happen. I read here to try the vice grip and tried that. Nothing. It just messed up the threading. Should’ve tried the old Double Nut Technique first, but didn’t think about it till after I mangled the threading. So, the only option (which I was and am still hesitant about) was to try and drill through and get it out with an extractor. Well, I got it in, but now the extractor starts to twist a little and might break if I turn it too much. The other option I’ve read here is to Dremel it out and rethread it. I’d like to avoid that if possible. I’ve used Liquid Wrench penetrating oil while trying to get this out. Thinking about going with a size up on the extractor. They were only like 2 or 3 bucks at Home Depot. Anyone have any suggestions or tricks they’d like to share?
