I have a 2009 Ultra Classic I recently put Vance and Hines Monster Ovals and Power duals, Arnel Ness big sucker and a cobra fi2000r tuner.My problem is it has an erratic idle and it will cough back through the intake manifold and shut the bike down. I took it to my dealer where I bought it at and they took the cobra off and said everything was within normal limits but they said the bike is running rich. I would think with all that I have done to it that it would be lean. I was thinking about putting a PCV on the bike and taking the cobra unit back any ides?
