Poke out all bleed holes with soft copper wire (especially ones in carb venturi)?
Ultrasonic soak is only to clean up chads and scruff left over from these processes.
Micro soda-blast everything?
ultrasonic does very little without these other steps
You'll also need to replace all rubbers: Fuel-rail O-rings, pilot-screw O-rings, float valves, float bowl seals.
Then adjust float-level with wet-test
ultrasonic is just 1st 5% of getting these carbs working...
Many experts who know these bikes like back of their hands have had to pull carbs 4-5x for ever deeper cleaning before they got them factory-fresh clean. One guy had to pull his carbs 10x!!!
