Say I'm in 6th gear at 2000 rpm cruising along in my 2012 FLTRX. If I roll off or on the throttle there is a clunk from below me. I never noticed it before. bike has about 15000 miles on her now. It's weird, like there is some clunky engagement of something. If I pull the clutch lever in and roll off and on the throttle the clunk goes away. What is this???

Primary chain needs adjustments. Put your bike in 2nd run up the Rpm's to abt 4k then let go of the throttle till it's just abt to stall then pull in your clutch. Just did mine, EZ fix. Would not do it to many times tho. Don't want to over tighten it!

It sounds like you may be "lugging" the engine in that gear at 2k rpm. To me that's a very low rpms to run. Try getting it to make the "clunking" noise at a higher rpms in that same gear.

Did it multiples times. No change. And it's not gear or Rpm specific. It happens in every gear at every rpm. Just can't hear it so well unless around 2000 rpm because of engine noise. Has nothing to do with lugging the engine.

Harley tech rode it and says it's fine but I suspect he never heard the noise.

Funny I noticed mine doing the same thing a week or so ago, I have 14k on mine, it doesn't sound like a compensator I know that sound, if I let off the throttle it sounds like the same clunk as if I was shifting gears,

My 13 seems to do this as well. I was thinking clutch adjustment but haven't checked it yet. I only noticed it recently with about 17500 on the clock. I'll have to wait to get her back to figure it out. It's in a crate on its way to the pacific for a boat ride to HI. I miss it already...

On my 13 custom i heard the noise on occasion but not since installing my Hayden m-6 tensioner. Works great for me.

I saw an independent Harley mechanic and I told him about the clunk; he went over to my bike and turned her on, put her in first gear and let the clutch in and out fast and it made the exact same clunking noise! He told me it must be the compensator sprocket. He says he knows that as of 2011 they were updated to the SE compensator on all regular FLTRXs but he says he has seen this before as well even with the SE compensators. He said that on a few he has put in the part made for the Trike system because it's a bit more heavy duty.

They since updated the SE compensator again.

I don't know what the problem is, but maybe it has something to do with lugging your engine in 6th gear at only 2K rpms.

Since when is 2k lugging the engine??

I get this same clunk/clank.
I can get the same thing to happen rolling OFF the throttle as rolling on. You don't have to do it hard to hear it either. Rolling off, it sometimes sounds like it 'bounces'. HD, as expected, said, "sounds normal for the compensator." Whether I believe that or not.

mine is the same, I figure the compensator will let go soon enough and I am still under warranty for awhile.

So if HD tells me this is normal what should I do? What sprocket should I get and install?
I'd stay stock with the stock flywheel set up. The compensators are failing due to lack of lubrication. The newest upgraded compensator kit supposedly solved that problem.
If you go with welded crank and Timkin bearing set up , and big builds, then there are better choices.
