I'm at 800ft in cincy and have pretty much the same setup as you (bore 87.5, q pipe, k&n, mild port, my carb is bored 41.5mm and I have v2 reeds) my jetting is 30 pilot and right now a 540 main needle clip 3rd position. My main is super fat and needs tuned more pilot is just right. Here are videos of my idle circuit tuning

25 pilot 2nd needle clip


27.5 pilot 2nd needle clip


30 pilot 2nd needle clip


30 pilot 3rd/middle needle clip air screw out about a 1/4-1/2 turn too much though
