I have a 2005 RoadKing Custom EFi that I installed a fullsac True Dual Kit and
replace the Air Cleaner with a Stage One Air Filter kit and now replaced the modify stock mufflers to a pair of screamin eagle slip-on Stage one mufflers the bike runs much faster but I am get a popping noise when it is in idle and in the morning when it is cold and i let it warm up a little and i hit the gas a liittle it hesitates a little. What could be the problem?

My best guess is you have a small exhaust leak causing the popping. As the pipes heat up and expand it seals itself off.
As for the hesitation, with the work you have done, you may need a good tune. Maybe just a Stage 1 download to go with the mods. Personally I like the PC's.

It's usually one of two things. Lean condition or leak in the exhaust header pipe. Sometimes both and seeing how you've opened up the air and exhaust, sound like that's the cause.

By going with OEM air cleaner, you REDUCED air flow to the engine.
Therefore you require less fuel
If you replace with stage 1 air filter, you INCREASE air flow, and you will need to compensate by increasing fuel ratio.
My first suggesstion would help you.
Here's another issue:
When HD did the stage one air filter, I assume they re-mapped your ECM for that filter.
Others need to chime in here to see in you're OK with an OEM air cleaner and stage 1 map.
With the OEM air cleaner, he's not getting the true benefit of the Stage I. It's just masking the problem which is either an exhaust leak, or more than likely an improper PCV map/tune.
Exhaust leak is always the first thing to check on popping. Did you use new exhaust gaskets when you put on the exhaust? Are you flange nuts tight? IF you have a tuner such as a pcIII did you set the throttle position?
