How is your fuel pressure? Good flow & pressure? Good gas? Check your voltage DURING cranking to be sure you are not starving your CDI of necessary voltage for correct operation.
I hope that when you did that shotgun routine, you ONLY sprayed carb cleaner down the proper jet passages, and not gotten carried away with the pressurized carb cleaner or pressurized air? If you spray down the wrong passages, you can, literally, destroy the coasting enrichener diaphrams and end up with bits & pieces of one or more of them blocking critical areas of your carbs. Don't ask me how I know that one, but suffice it to say, that is when I first found this forum.!!
If you confirm good, solid spark on the plugs, good solid voltage DURING cranking, and good, solid fuel pressure, then you may want to pull the carb rack and go through them properly to inspect for blockages throughout.
