Angry Knock noise

Hi all. I recently purchesed a 2008 superglide with 9000 miles on it. My previous bike was a 2007 sportster 1200.I notice a loud noise when the engine fires when staring. It is a single clunk. The bike runs great, very smooth and no engine noise, just the single clunk in the starter area. It seems as though I have heard this before on other BT engines. I don't know that this is not normal, just not used to this machine yet.This noise is produced when the starter is disengaged as the motor starts. Sound familiar??

It's most likely the POS compensator

My 2007 Dyna does the same thing. I just got used to it.
