Problems with Compensator

Is this issue only with the touring line or all the 96 inch motors?
My son has a 2010 dyna fatbob that makes the same bang noise on start up. Not as bad as my flhx but close.
 
I had the same noise when the clutch was engaged and released slowly it would make a noise. I took it to one Dealer and they said it was normal for 08's. I took my bike to another dealer for a service and when the tech started the bike and started to move it he heard the noise. Then right away he said ,sounds like I had a loose compensator nut. Then under warranty they inspected the primary, changed the fuild and tighted the compensator nut. So far everything is ok.
 
Had a chatter in mine from day one. My warranty was 3 months out and Harley covered it and a few other revised parts. My total cost was 100 +100 to go with SE comp.

I have an 08 Street Glide, they covered it under a "good will" warranty.
 
The HD Service Manual and a tool to lock the two gear sets together while you remove and assemble them (picture of one in the SM). Other then that, a few sockets ( 1 3/16 socket included) and your set. Mine's apart now, the new comp will be here today.
 
The clunk you hear at start up, is the starter overcoming the spring's tension capabilities in the compensator as it ramps up and bottoms out on the splined shaft. The starter gear goes from a damped system to a hard hit as it bottoms. The hard hit is what causes severe stress on the starter gear. The SE Comp uses a different system of springs (concave washers) that allows for more progressive damping before bottoming, and far more force is required to bottom the SE Comp springs. A force the starter won't or shouldn't totally overcome.

Yes it is on the crank, but it acts as a system, with the primary chain connecting it to the clutch basket/flywheel. So when the clutch basket/flywheel turns, so does the compensator.
 
Scorpion07 - Great Description, thank you for that! I am mechanically inclined, but I have never had a compensator out or been able to look at one to see how they work.

I just made an appointment to get my 10 Road King in at the dealer. I figured I would let them do the work under warranty and I'll pay the difference in the compensator. This way it will still be under warranty for another year. That way if an SE SE Compensator comes out that fixes the SE compensator on the 11's, I can get that next year!
