are my carbs to big? and jetting help

[Hoonigan057]

i am currently running dual 34 keihin carbs. it idles but bogs real bad in the mid power range. 

it has a 392 athena big bore, cool heads, 22cc domes, vforce 4 reeds, billet intake, fmf pipes and silencers, oversized radiators.

it is about 25-40 Fahrenheit and about 600-700 feet above sea level. 

any recommendations on carb setting would be greatly appreciated. thanks for looking
