That knurled knob is your idle adjustment-on left side of bike. One thing to check is to make sure your rubber intakes are on right side up if you took them off. There is a pic in the tech vault.
TPS is located on right side of the bike.
150 mains with epco and pods sounds about right without looking at the calculators. If you turn the D screw all the way in counting the turns (I put a black mark on the tool to count the turns) then turn it back out. Start with 2 turns and kind of play from there. Both sides obviously. It's a good easy and free place to start.
Hope that helps some.
