Just a little theory, and no first hand facts, but you might find that your primary tensioner is a little "slack" in handling it's job. Harley primary chains probably stretch more in the first 500 miles than they do in the next 20,000 miles, as anyone who did their own manual chain adjustments in the old days can attest. If the chain stretches and the auto tensioner doesn't ratchet properly to take up the new slack, I could see this causing a slapping or ticking noise. And failure of the tensioner to adjust has been reported as a verified problem by some folks.
If it doesn't resolve by itself, have the dealer pull the outer primary cover and check the tensioner. If that isn't the problem, check out the clutch. With a hydraulic clutch there shouldn't be any free play that could cause your symptoms, but with all the issues H-D seems to have with their CVO hydraulic clutch, who knows? Does your clutch seem to drag with the lever against the grip, and engage almost immediately as you start to release the lever? If so, you may have air in the system. A
thorough bleeding might be all you need.
