loosend, I have the popping on decel too, and have rtv'd the heck out of the inlets to the Bubs. I have my screws at 3 turns, but have tried 3 1/2 turns and 2 turns. All the 3 or 3 1/2 seems to do is make the exhaust tips build up soot, from what I can see. Am going to look around some more and see what I can find. Oh, and I had to go to 130 Mains when I went to Bubs. The dealer didn't change the Pilots though. Let us know what you find...
