need help jetting 421 kit with 2-1 carb

[Voest-Alpine]

I was wondering what you all would think would be a good base jetting for a 421 kit with v force 3 reeds and 2-1 carb, im having trouble getting my bike to run right. Misses and pops some through the rpm range, doesnt want to hit band hard.

You need to list everything done to the bike, and which carb you have on the 2 into 1 intake.
