Clunking when letting off throttle
I recently did a trip from Florida to Kentucky driving through the mountains of Tenn. on my 2013 Ultra with 7600 miles I experienced an unusual noise from the primary area. when letting off the throttle or giving it gas I would get a distinctive loud clunk. Shifting appeared normal. Interesting, returning to flat land traffic in Ga. the clunking stopped and the throttle let off was normal and quiet. Stopped at a H.D. dealership on the way home he thought it might be the compensator spring. After returning home to south Florida I spoke with my dealer, he seemed to think it might be the automatic adjustor on the primary. Just curious if anyone else has had this experience. Thanks in advance.
Compensator.. mine does the same thing... if at low rpms, on and off will make a clunking noise in the primary.. I had my dealer open it up last week and they verified all was in order there, everything was tightened to spec... i don't hear it all the time, but yeah, its noticeable if you are in any gear and coasting along at 1500 rpm.. probably should not be lugging things that way though

mine makes a noise. Much more noticeable at lower rpms. Hear it good when I am coasting and turn on the cruise. No tach so can't tell you numbers. Service guys rode it and said nothing out of normal.
In discussing it, i did learn more rpms are 'sposed to be better. That's when they told me not to be putting along in 6th at 60 65ish mph. He said 70+ minimum. I have learned my "noise" is less when I run a little higher on the rpms. I cruise the ozark hills most of the time. Lot of accel/decel and few long flats

Try riding in a lower gear. Low rpm's in high gear creates slack in the drive train making the noise. Riding in too low a gear is also hard on the engine.

The sorry *** cranks in todays Harley motors seem to be most happy at about 3000 rpm. After getting up to speed, riding at less than 2000 rpms (lugging) is just asking for future drive-train and engine issues. You guys without tachs are especially susceptible to lugging since you can't see where your engine if operating.
I ride a lot at 2500, and I try not to let it fall below that when at speed by varying the gear I'm in to compensate for the speed I desire. Rule of thumb: Keep the engine humming along...you will be glad you did.
