the tuning spreadsheet is very helpful. From the looks of it a 64 jet looks popular with a your setup. remember you have to take in to account altitude and temperature of your location. oh and for air filters those are your two options I couldn't tell you which one flows more but I have the generic one and I can't imagine the Malossi one flows more cause the one from treats has very corse open cell meshy foam. but more isn't always better.
