It is tune with a Dyno Jet Power Commander. How would I know if that is an issue? I need it on the bike to manage the needed extra fuel, right?
I am most likely pulling the Hayden out but I will reserve making that decision until I open it up and inspect.

FWIW, the IAT sensor and the MAP sensor are two different things, and neither of them is a MAF sensor.

OK I played with it some today. The throttle body was nasty. I used 2 cans of carb cleaner to get the funk out. The oil vapor lines are now routed underneath.
The surge is still there some. I am not certain how bad because I was riding solo. It seems to be worse 2 up with gear.
I checked the intake and all looks good. he plug on top was still there and no apparent intake leaks.
I pulled the Hayden tensioner and checked the belt deflection. All is good on that front.
Someone posted plug the O2 sensors back in to see if it corrects the problem. I am assuming I can do that with the Dyno Jet PC still hooked up? If so then why wouldn't the tuner leave them hooked up?
I still think the bike is surging because it is lean. The pass side slip on is discoloring and I know it should not be doing that. I will not see my tuner again until Oct so I am concerned about riding it all summer that way.

As for the o2 sensors, the eliminators are small plugs with a set value resister embedded in them that plug into your stock wiring harness to fool the ECM that the o2 sensors are still there. So I would say yes, you'd have issues if you remove them without removing the entire PCV from the system.

Todd,
I didn't pull the throttle body but thinking I might need to. It was nasty in there. I used 2 cans of cleaner before it came out clear. I see the sensor coming in from the top and it was black. I did the best I could without pulling it. That may have to be the next step. We are leaving the 10th for a 4 day no destination in mind guys ride, so I would like to get it straightened out before then.
