don't forget you have 2 mains and pilot jets. Left carb is one size leaner on the main. I only have an Alba Pipe and Pro-Flo filter kit on mine. I have 160 and 162 mains in it. I would imagine with you having it bored .030 over, and porting, you'll need 2-3 sizes larger than mine. Probably only have to go up 2 sizes from stock on the pilots. Adjust the airscrews 2-3 turns out, do this while the carbs are off, as the pilots are a PITA to get to.
