What about a blocked air vent in the fuel tank? Try and start it with the fuel cap slightly open. Probably best on the centre stand again. (NO NAKED FLAMES and PLEASE BE CAREFUL)
A couple of weeks ago I had the carbs out three times cleaning, checking, cleaning again. Finally got it running nicely and balanced etc. Fast forward one week, rather than leave it several weeks, I started the bike again to find it was only running on 3 again.Today I took the carbs out and found #4 bowl full of crap again with the jets blocked again. Time to drain the tank and fit a new filter I think
The filter and pipe look fine and the fuel is getting into the carb bowls...I'm getting suction at the carb mouths too but just can't work out why the plugs would be bone dry....I blew through the Jets etc when I cleaned the carbs and didn't see any sign of dirt inside... can't think of anything else it could be though apart from the carbs, but, also seems strange that it's affecting all of them not just 1?

Is there fuel in all the float bowls? Also check the air intake for the air box, another very common fault is things being sucked in like rag etc.
Did you try without the air filter in?
