What modifications do you have? That carb isn't going to make any power for you. That big carb will only frustrate you when you try to tune it. Its not needed. Don't fall for all the internet bull sh&t.
Big bore wiseco +2crank and high compression piston aggressive port polish full fmf power core 2 and fatty. 2 stage Vito reeds open box with a custom k n filter over top of box
I just saw it on Craigslist and add of now with stock carb I'm running 320 main stock pilot 2nd clip needle. And figured the larger carb would allow more fuel
M suggestion is to add a few bucks to that $40 and send it to
http://www.kenoconnorracing.com/ For a professional head re-chambering. Lots of power in the head after the proper squish distance is set/checked (about 1mm) and proper jetting is achieved. No bullsh&t. Give Ken a call.
if you want more power'
and dont have a rechambered head do it..
it will help more then a complicated carb set up
and boost the compression up more then what you have know
