Stuck screw in clutch cover
Spitfire:
It was at this stage with my cylinder head that I wimped out and took it to the local engine (car) shop, I tried the hot cold, treatment, the violence, the penetrting oil but when I ended up with a stud broken off flush I knew it was time for me to quit, the cost of taking it to someone else was peanuts, the cost if I messed up would have been far greater.
Cheers

Seems like the exact stage I am at right now Dennis!
Did he get it out with threads intact, or how did your situation end up?
K2-K6:
For your clutch one Alex, if you can get a nut (10mm) onto the stud, then get it welded to the stud down in the recess to fully bond the nut and stud together and effectively give you a bolt.
Then, don't try to undo it with torque, use a drill/screwdriver (specifically not an impact driver) and use it with a socket adaptor to persistently rattle the stud anti-clockwise. It may take time but it should eventually and gently loosen the stud. The heat from welding it will help too.
McCabe-Thiele (Ted):
If as it appears you are stripping the whole engine down I would press on with the dismantling see if any other bolts are going to be difficult then see if any other engineering jobs need doing then decide if it worth going to an engineering firm to get any issues that arise done.
FWIW I could not get the big Crank case bolts undone as my cordless impact gun did not have enough torque for the larger bolts. A friend came to my assistance with his Mulwarkee Industrial Cordless Impact tool and they all came out easily. A local engineering firm put a pair of Helicoils in the casing for the tensioner arm as I did not trust myself to do them. (One was stripped)
I even bought a spare casing as insurance just in case it all went wrong. Nice to have a spare if I ever needed it - it came in handy when I had an issue with gearshift movement as a comparison and source of gear parts that I did not use in the end.

Drilled out and an insert fitted, the bike had sat for ten years and what had started out as a quick turnaround ended up taking me two years, luckily when I took the top end apart the only thing that needed attention apart from the stud was one stuck piston ring
