you beat me to it^. if it seems to happen when you are getting on it from a lower rpm until it reaches a higher rpm then stops that is probably what your problem is. it is caused by an incorrect air fuel mixture. if you can determine for sure that is your issue i would drop the cash on a thundermax or power vision. either of these would cure your problem and make your engine much cooler and smoother by allowing for a richer air fuel mixture. stock sportster are very lean from the factory.

My 2011 Iron makes this noise too. It's really annoying cause its so loud at times. My buddy has a 2012 48 and he has it too.
He actually brought his bike into the dealer and they tore it all apart and told him everything is normal. They even ended up charging him because nothing was wrong so thats why I'm a little hesitant to bring mine in.
From what I've read, it seems the people with the Iron and 48 complain about this the most. It seems to be because of the smaller/narrower gas tank.
On my bike if I put my left leg up tight against the bike it almost goes away completely. The sportsters with the larger tanks seem to block the noise (just like putting your leg against the bike)
It still doesn't seem normal but I have a lot of people tell me not to worry about it.. I have a 3 year warranty so I guess if she blows, then she blows.. Time will tell I guess.
