I chemical Metal'd one of the bolt holes on my flywheel cover. It was however just a blind hole as the chain cover on the main casing has been broken off at some point. I tapped it out M6 and it now just has a blind bolt in it so it's not just an empty hole. It worked a treat!
The trouble is that the M/Cylinder threads are only M4 to that's a tiny thread, however there isn't much load on it so it might be fine.
You've got nothing to lose by giving it a try?
I reckon you'll just about be alright.

JB Weld works OK.. but despite the heavy advertising budget, it's actually a low grade epoxy.
One can buy substantially better goop.

I've used various metal and alluminium based 'DEVCON' epoxies over the years and, if used correctly, usually do a wonderful job. A bit expensive but WELL worth it. Mike |
