Find out which side is not firing by pulling a plug wire. Not sure of how the fuel hoses are run, but if the left is missing, excess fuel could be causing the problem. Crud in the float valve, floats sticking or riding too high from wear maybe. Does it have a vacuum operated fuel petcock on the tank? If so, the diaphram in the petcock could be leaking and putting excess fuel into whichever carb it connects to.
Here's some things to consider. Does it do this only when parked on the side stand, centerstand or both? If a manual petcock, do you leave it with the fuel turned on or off? If on, try turning the fuel off when parking and see it anything changes. Pull the plugs and dry, black soot is too much fuel, not oil. Oil will leave wet, black gunk. If one is dry and sooty, then it's running too rich all the time. Start it and let it run while it's missing for a bit, then pull the plugs. If one is wet and smells of gas, then too much fuel before running or during starting. Before tearing into things, try to find out what makes it miss and if it doesn't what you did to change that.
I wouldn't consider the electrical system just yet. Many of those components work fine when cold but go bad when they and the engine get hot. Look for fuel problems.

Make sure the oil level in the engine is correct -- not too much. If there's too much, let some out.
Clean off and check the gap on your spark plugs.
If you have more than one air filter, it might be time to clean the elements (if they can be cleaned).
You might have an "iffy" tank of gas. Get a little bottle of carb cleaner gas additive. Use a quarter of the bottle to a full tank of gas. Close the bottle tightly afterward for future use, or just dump the rest in your car.

it is an old car...but there could be a lot of carbon build up in there that is interfereing with the gas igniting... get one of those fuel additves for like 15 bucks, add to a full tank, and just drive normal for the tank. if after the tank it seems to be getting better try another treatment and you should be good to go
something similar hppened to my '87 bmw and the carbon treatment worked pretty well for me. and if it doesnt work for you then you only spent 15 bucks instead of a couple hundred for a mechanic

Nice bike (not a car)
Your spark plug will tell the story. It could be a lot of things right now, and the plug will tell a tale to a trained eye.
$501.00, any other bids! Just kidding, you have a nice piece of history, and a good highway bike!

next time check the plugs before you start it...
how they look can give an indication of whats wrong..
if one of them is sooted up then the bike is getting oil in the combustion chamber...
if not you could have a bad earth on one of your coils...
Its a case of keep checking untill you find the problem.. eliminate the probable causes one by one till you find it..
