Help with Starting point on New Engine Setup

[Infamous039]

Please give me some advice on jetting my new setup. I need help on starting with a Main jet and Air Screw. Bike currently runs and idles great with no hesistation. I have 320mains currently, which maybe kinda lean. Please give me some pointers of what I should be close to when bumping up on the mains??

 

I mods are:

CT Racing Ported Cylinders (see SIG pic for type of porting)

Stock carbs 30pilot jet

Coolhead 21cc

Rocket Pipes

Vforce 3 reeds

+4 timing advance

KN air fitler

 

Temp:70-80 deg.

I figured I was kinda close with the 320 mains. I ordered some 330 and 340's to be safe. I am going to try them out and and see how it runs. I prefer to be a tad rich just for some insurance that its good.
