Unless you are tuning with an air fuel meter, just follow the Dinqua jet tuning calulator guide in the tech section (presuming it is still there). Just plug in the closest to the choices you can find...that will get you in the ballpark.
When you dunk cleaned the carbs, did you pull out ALL of the rubber bits first, including the air cut valve (acv) assembly on the port side carb? If not, I suggest pulling the carbs, fully disassemble everything you can, & check everything again. My guess is something did not get done right the first time.
Are you running the OEM airbox & airfilter?
