Yeah, standard Lucas or pattern stator and rotor found on most English bikes. No way to tell if the stator clears the rotor, except to start it up and see if smoke pours out of the inspection hole.

Could you wrap a couple of layers of masking tape around the rotor temporarily fit the cover and then remove it to see if there are any marks present after turning the engine over a few times?

Yes, you could - and should - do that. Just check the first few times you run it to make sure the rotor doesn't touch anywhere. I lost one stator after almost 3000 miles. Apparently, the rotor and stator would occasionally touch, and eventually galled up enough to fry the stator.

Engineer's blue is only useful for surfaces that are supposed to touch, the stator and rotor are meant to have an air gap between them, if it touches anywhere you are in trouble. Some wraps of masking tape should show if it is touching anywhere and hopefully by how much. Start off with several wraps around the rotor if it touches keep taking one circumference worth of wrap off until it is clear and that is your gap.

Not done it meself but seems a feasable way of doing it ,just nip up the stator nuts/bolts then wrap shim steel of the right thickness around the rotor then try the cover onto that .

On my Matchlesses I wrapped the rotor with shim stock (plastic shirt collar stiffener piece from a new shirt cut to length) and then left the bolts finger tight (able to move with a little bit of force) on the stator. I'd put the cases together and bump everything around a bit so the screw holes were centered in the cover, then remove the cover straight off carefully and tighten up the stator bolts.

In the past I had used car wax the see if and where it was hitting. Didn't work very well. The idea of using electrical tape make a lot of sense. I would use longer cover screws to keep things in line as you draw the cover up.
