It sounds like you dont have the bike on the road yet.
Carb cleaners work by flushing the fuel thru the jets and passages while the bike is running. Letting it soak in the carbs helps a little, but the amount of cleaner in contact with the goop or varnish on the surface of the jets is nearly nothing compared to when the bike is running.
If I remember correctly there are three paths thru the carbs when the engine is running, based on throttle position. When the bike is idling nothing is flowing thru the main jets, the Pilot Main passage kicks in somewhere in between.
To get the best cleaning effect you need to ride the bike, and that includes spurts with the throttle WFO, going up a steep hill if possible. If the bike will run at all Seafoam will do its job.
If you cant get the bike to start, or if it will not make it around the block, then you need to take the carbs apart and have at the jets and ports with piano wire. When the jets are fully plugged nothing can flush thru them but steel wires.
