Here's a WAG, since I never had a stock TORS Banshee.
I'm not sure if you can even this, but this is what I'd do.
1st, make sure carbs are sync'd by visually seeing the dot on the slides thru each carb's site glass.
Then turn the air screws in until seated, then turn them out 1.5x.
Next turn the idle adjust knobs equally on the TORS to raise the idle.
Then fire it up and see how that works for you.
