Right now with Pro Circuits, K&N Filter W/O Lid, Boyesen Reeds, Stock Carbs, i have...25 Pilot, 310 Main, Air screw 1.0 turns out. But that was for the warmer weather. Im at 900ft+ sea level, and its around 0-10 celcius right now, so im going to get some 27.5 pilot, and 330/340 mains, and then fiddle with the air screw. Maybe this will give you an idea :beer:
