Pop, Pop, Pop ... is this normal?
I picked up my bike last week after a new dyno with my SERT and the new 103 stage II. I am very happy with the way it rides now and the additional power is just what I was looking for. It was the best $1400 I've spent on the bike yet.
However, I get a LOT of popping (I'm sure there is a name for this but I don't know it) from the exhaust nearly every time I get out of the throttle or downshift. Before the new build I hardly ever heard this. Is this something I should be concerned about?

I assume you get the POP (AKA backfire) with deceleration/closing the throttle? Have the AFR (Air-Fuel Ratio) checked by the shop that did the dyno. Or it may be an "inherent" side effect of the exhaust set-up you have.
When I had Thunderheaders on my old '02 FLHR, I learned to live with the pop because the bike ran fine otherwise. The shop said they can minimize the pop but the bike's tune will not be "ideal"
