Ok, so I was just trying to change my oil a few minutes ago. No matter how hard I turned, the damn bolt just WOULD NOT TURN. This by itself doesnt make any sense. Im the one who put the bolt ON last time, so the absolute tightest it could possibly be would be limited by how hard I could turn it. So unless Ive lost a TON of strength/muscle since putting the bolt on (My arms have actually gotten stronger since then due to my new job) its completely impossible for the bolt to be too tight for me to remove.
I tried plenty of WD-40, I tried with the bike nice and warmed up, and I tried with it completely cooled down. No matter what I did, this bolt just defied the laws of physics and refused to budge AT ALL.
So anyway, about 15 minutes ago, I was giving another shot at getting the damn bolt off, and all of a sudden, the socket wrench starts to turn, but the bolt doesnt turn at all. When I look at it, it literally looks like its almost completely circular. the metal was so insanely stripped. It looked like the metal was peeled like an apple. There is no way in normal metal should just scrape off so insanely easy like that.
So now, Im sitting here with a scooter that I cant change the oil on because the oil drain bolt is possessed by satan and likes to completely ignore the laws of physics. Its stripped to all and back, to the point where no wrench, socket, pliers, or anything else will get a good enough grip on it to turn it.
Whats the best course of action here? Is there any way to fix the bolt, to make it un-stripped enough to remove it? What about the impossible immovable-ness of the bolt? I know for a fact that with the amount of force I was applying, the bolt DEFINITELY should have turned, and yet it didnt budge at all. Even if I can fix the head of the bolt so a socket or wrench can grip it, how can I get it to turn when it seems to be a literal immovable object?

Get a screwdriver or chisel and hit it on the side at an angle " LEFT " to unscrew, just had another guy on here with the same problem. And do it when it is COLD not hot, when hot everything is tighter. So let it cool down so it retracts. Alleyoop

I was that other guy... The hammer and chisel really works. (I really need help forum)

Happened to me too and I wish I knew about the chisel method. That sounds good. I used a pair of vice grip pliers and that worked. You might think about having a new plug at the ready when you get the old one off in case it won't go back on either.

Another bit of garage-trickery you might think about is using differential temperatures to your advantage. While it's true that in a warm engine everything will be tighter due to expansion, you could try selectively chilling the bolt itself to cause it to shrink. It's like the reverse of using hot tap water to loosen a lid on a jar. The best way to achieve this (for the average lay-man) is with a can of, well...canned air..you know, the stuff used to 'blow out' computers and suchlike. If you turn the can upside down you will release the liquefied propellant which will behave very much like propane or butane does when exposed to atmosphere as a liquid...it boils off rapidly and freezes just about anything it touches. Those 'canned air' products usually come with one of those 'red straw' thingummies for reaching tight places. that should allow you to target the bolt itself, while holding the can upside down. just warm the scoot up completely, then target the bolt and give it a few good blasts until it's cool to the touch... that should give whatever benefit a temperature differential will be able to afford in your situation. If all else fails... www.sears.com/craftsman-10-pc-damaged-bolt-nut-remover-set-low/p-00952166000P Good luck!.

Seems odd that you can't get off a bolt that you put on yourself, especially one that is removed and replaced so often. The question that first comes to mind would be "You're turning it the right way right?" Just sayin'.

Maybe take a die grinder, or Dremel, and grind it flat on two sides, and use an open end wrench on that. Use 6-point wrenches when you can over 12-point, those can strip cheap metal or tight connections. I've also tried cutting a slit in the head and using a flat screwdriver or pry bar.
You can try switching between the cold compressed air and a torch lighter. Just make sure there's nothing to light on fire. Not sure if yours has a rubber O-ring for a seal. May need to replace the whole thing.
