Changed the oil today and the thread has stripped. This is the casing and not the plug itself - main drain, not the plate with the gauze behind. I'd noticed it was a bit iffy last time - tight to unscrew and hard to get it to bite when replacing. I know I didn't cross thread it, and I didn't over tighten. If I'd remembered before I started the job this time I'd have drained the oil by only removing the plate.
I can get it screwed back in, but it wont tighten. A bit of what looks like the stripped thread came out as I cleaned the hole with a rag.
Any ideas? Other than taking it in for repair and hoping to swing it under the warranty?
I thought about screwing it in with J-B Weld and just using the other drain hole in future, but this doesn't entirely appeal.
I was looking forward to riding this evening and tomorrow, dammit.
