Would a blockage not rather cause a fuel shortage instead of to much fuel?
No not if it's air.

The bike doesn't have a choke in the real sense, when you pull the choke lever out, look closely at what happens, it pulls out 4 plungers, they can stick open even when you push the lever back in. This cuts off air at low RPM through the pilot circuit, thus enriching the mixture, so when you rev the bike when it's warm with a stuck open plunger it's over fuelling.

OK now I understand. I took a good look at it. When I push the choke lever, all 4 plungers move properly. But perhaps the one of cyl2 is faulty on the inside? I will open up the carb next week and have a good look at it.
Should I open up the top half of the carb to do this? Or is it an issue which can be solved from the lower half?
Could I screwed this up when overhauling the lower half? Or is this a coincidence? (or maybe my manipulating/rotating/... the carb some debris got at the wrong location...)
