Went to pull the flywheel looking for the missing airbox screw (see previous post... was just being super cautious.) About half way off the fly wheel nut got tight again. Weird. Tightened it back up and hit it with some penetrant. Again about halfway off it started to feel tight and like a cro-mag I gave it a little muscle... it gave and came off but it didn't feel right.
Cut through like butter and the end of it sheared in the fly nut. Went on fine. Torqued to spec. No idea how it got cross threaded or much less how it sheared given that I wasnt on it with a breaker bar or anything.
So close to being done and now so far...
