Whats PB?

When backing out a bolt that seems to keep tightening try a good shot of PB. Then do the "start to loosen then tighten then loosen and tighten. trying to back it out a little more each time" as stated by RangerRick. This has saved my a$$ several times.

I dislike these button head . I just had a 2nd one round out . This time was one you need to remove to get that plate off to get to front tank bolts. Its was soft as soon as I started turning it gave way . (Yes I was using the right size) . This is the 2nd one . Iam going to replace some of these with a proper bolt . The larger ones like fender are fine its the small ones.
I'll chime in on this one with personal experience on my Raider. While removing the left side frame mount the bolt which goes into the rear head seemed awful tight. I summed it up as lock tite and kept turning, once out I realized the bolt was bent and as I turned it out it chewed up any thread I had left. Long story short I managed to drill it out, and using a heli-coil I managed to save it. The stock bolt now threads in with ease and using only my fingers.I've heard of stripping spark plug holes as well, this is more common than you would believe especially in the automotive industry where car makers make getting at spark plugs a nightmare. Several companies sell tap and heli kits suited for spark plugs in particular. You will be forced to remove the head when doing this so you don't end up with metal in your bore.Cheers,Actually, a good heavy bodied grease applied to the tap will catch the cuttings. I've done this many times w/o pulling a head.
