Anytime you tweak the pilots you want to have the option of resetting the air mixture at idle. So take out the brass plug that they put on the air screw so you can fiddle with the air screw...Set it to 3 turns out.
That should do it.

If you want to do a stage 3 - Take off the airbox and put K&N's on instead then you need 150 mains. The rest is all the same as the K&N's in the airbox.
