The snow is melting and I'll get the bikes out shortly. I was going to install an HID globe to the 1200 but couldn't get the headlight shell open, backed off the bottom screw about 4mm but couldn't get the shell to move. Do I need a 'technical tap' or remove the screw completely? Chances are the headlight shell has not been opened since 1979.

A large blunt flat bladed screwdriver usually works for me, pushed into between the rim and shell where the screw sits. Using an old blunt item helps reduce the risk of scratches when applying a twist to the handle.
 
well that method does work for popping 4x4 or plant tyres back onto the rim, in the absence of a dirty great big dump tank, so why not, I mean the best thing to do with the wiring in the shell is blow it up!

Ok ... tri
Get a propane torch, turn on the valve but don't light it. Squirt some propane in through the wiring hole at the back of the headlight shell, then light a match and poke it in the same hole. The headlight should come out.
OK .... tried that and it's still attached.

So, just to be sure, if the retaining screw is wound out completely do I loose a retaining plate (into the shell) or will there be a 'stop'? Or is it routine to just loosen the screw and get some movement? The idea of a blunt driver of sorts to lever the lens off should work but I'm just be careful (scratches) atm. I was hoping a rubber mallet might be the right 'technical tap'.
