Pop/ Backfire at start up

It never happens when the engine is cold, but on a restart the engine will produce a loud pop or backfire. It dosent do it all the time, I never know when it will do this. Has anyone else had this happen?

thanks

Did the Fuel Moto power package, but it would do it when it was stock.

might be a design quirk of the exhaust (the Thunderheader slip-on I had on my old '02 FLHR popped on decelaration). Shop said not much they could do due to its design.

Maybe give Jamie a ring so he can tweak the AFR of the map loaded in the PCIII. Best of luck.
