Rebuilding an 08 RM125 for a friend, and on reassembly the final bolt I was putting in of the crankcases stripped the threads out of the case without even getting to tightening point. Are there any self tapping type screws/bolts that would suffice or do I have to strip it all down again and see if there's enough material for a proper thread repair?

Hopefully someone can point me in the right direction of a good quality easy fix.

Helicoil and Timesert would both require splitting cases. There is liquid thread repair but I have not had success with it.

Pics would help. Most case bolt thread holes have very little metal around them, not enough to be able to drill/tap/insert.

In that case, best bet might be to weld/drill/tap. In either case, you're taking everything back apart.
