Update:
Dealer says its normal but that was sales rep who has the same bike. My friend with a 14 Street Glide says his did it when new but eventually got quieter. I just had 1000 mile service and my slip ons installed. Still does it but now I almost can't hear it.
I still don't think its "normal" Its almost as loud as my shifts - depending on how hard i goose the throttle, or let off the throttle. I'm not going to worry about it for now. Thanks for the input everyone.

My 09 does something similar but it only happens occasionally when I brake. My noise seems to come from the front end or right under the gas tank in that general area. Neck bearings?

Hello all. New to the forums. Just picked up a black 2016 Road Glide Special. This is my second Harley - an upgrade from an 02 Road King Classic. This is my first new Harley so I'm not real familiar with any of the quirks when the bikes are new. My question is that loose feeling clank sound when you first accelerate and decelerate the bike normal? Its not quite as loud as actually shifting but its pretty noticeable. I've read that shifting can be loud, and it certainly is, but this is something different. My old bike with 50k miles didn't seem to have this. Let me explain it another way also. Turn the bike off. Leave it in gear. You can move a couple of inches forward or backward before the tranny stops you. But at the end of each movement there is a clank. Maybe this is normal but I just want to be sure. Any feedback would be appreciated. Thanks.
Have you heard the rocker clatter yet?

Clank
It's your auto adjuster for the primary. Put the bike in first gear, not running.
Rock the bike forward and back, a number of times. 5 or 6
Take the bike for a test ride.
If still sloppy, rock it agressively!
Still sloppy, start the bike, on the street, put the bike in gear, start moving down the street applying the rear brake. The idea is to get the self adjuster to bump up. Not too much throttle!
The adjuster is supposed to adjust Under acceleration.
If there is slop "clank" getting on or off the throttle the primary is out of adjustment.
Rod
Note I prefer the rocking method.

This sounds EXACTLY like what I was talking about. It feels sloppy like there is "blank space" in the drive train or something. I know all bikes have it to a point but the "gap" on mine feels just feels really big. My 02 Road King had it but much less so and it didn't make the noise (50k miles) When you "run into" it accelerating you hear the clank, and the same thing when you let off the throttle. I'm going to give that a try and see if it "tightens" up. Sorry for ridiculous use of quotes. lol

Chains stretch under use and need adjusting, whether a chain driving a wheel wheel or the primary chains.
When they stretch you end up with that sloppy feel or lag when you get on or off the throttle.

I don't want to start an oil thread but, my bike sounded like I had piston slap and bleed down was so pronounced that it took over 5 miles before the lifters would pump back up after I turned the motor off for about 30 minutes. It almost sounded like the top end wasn't getting any oil.....All that noise went away after about 1k miles going back to conventional motor oil from synthetic. Even with all the noise the dealership would tell me it's normal!! With all this said, are you using synthetic oil in your bike?

I have a warranty program on the go with my 2014 limited, so I'm sticking with harley mineral oils.
Make sure the primary gets the req'd amount. I think it's about 4 oz more than a quart or litre.
