So I have these stripped flywheel bolts on a new motor I bought. It has some ebay crap FW on it now and I have an act light weight FW from my old motor. These bolts gotta go.

My only thought is to use a dremel to file them down a size.
 
I wouldn't do the dremel way. Pita and why spend all that sweet ass time doing that when you can buy a ~50 dollar craftsman bolt extractor set?
I accidently stripped one of my flywheel bolt when pulling it. Bought that set, bolt came right out.

Ps. Those bolts are hardened steel. dremel would be slowwww....
 
Or you can hammer a cheap socket thats too small on each one and pull em out that way with an impact. But the bolt extracter set will most likely be cheaper, and you can use em again when a bolt rounds off. It will happen more, its a DSM.
 
How did they get stripped? Wrong type/size of socket? Torqued too tight? If you stripped them while trying to back them out with the right socket, I doubt an extractor is going to do the job. Drilling might be the only way.
 
Factory flywheel bolts have really thin head. They are torqued tight, have threadlock on them, and maybe some rust after a while, and especially if the socket is worn or not on the head all the way it's pretty easy to see how a bolt's head can get stripped. Quality aftermarket bolts have thicker head and are 12 point instead of 6 making them much harder to strip.
 
I had this happen before and didn't have my bolt extractors handy so I just welded a nut to the bolt and then just zipped it off with my impact gun!!

But I think the bolt extractors are you're best bet:thumb:

I can say that irwin bolt extractor works very well, I had some stupid rims that my gsx came with. the guy was also nice enough to use 3 different "tuner lug nut" patterns and sizes. The bolt extractor made easy work of them; they were over torqued and rusty too. Great tool
 
I stripped mine by using a twleve point cheap socket on it. At the time only had that socket. Engine was also allready on an engine chain. The heads are very shallow and I tried almost everything but welding to get it off before I sacked up and bought the set which worked phenomenly well
