stuck rotor bolt

[GSSzucs]

Hi All!

My problem starts elsewhere...

I haven't got any spark, I think it's electrical, but not. When i pull off my left side cover and try to start i realized, that my gear behind the rotor doesn't spin the crankshaft, so my contact braker doesn't work, so i haven't any spark. If i'm not mistaken.

So my problem now. I've got another block in my garage as mine (a GS1000 E from 1979) - it's not a problem, so i think i replace the 2 rotor. But i couldn't pull off my rotor, because the bolt is stuck. I've tried everything (force, hammer) and i've a holder to prevent the rotor to swing. Any idea how to pull the bolt out?
I'm afraid to try on my bike, i don't want to make more trouble, so i try anything on the separated one.

It might have had a problem coming loose in the past & someone green or red lok-tited it. Id try some heat on it, the green stuff is badass. Once its hot try an impact driver or a 1/2 inch drive air ratchet. Might help to put it in gear also.

Thanks.
Am I right, that a lighter won't be enough?
