The way the cap freely moves after securing with the first snap it would appear some noise might be inevitable. I don't hear anything because I wear full face with ear plugs.

I wear full face with air pods, could still hear it especially when accelorating. It was really annoying because I like to hear my motor as is, not with added noise vibration. The replacement cap is exactly the same as the original cap that came with the bike - minus the vibration noise.

Look under cap and on outer edge where cap rotates use a hammer and punch to indent. Problem fixed...

I've had 3 different late model Harley's that have done this, including my 2018 Lowrider. All 3 replaced under warranty. If you rock the cap you can hear it really well. It's funny some dealers still scratch their heads and say they've never heard one do that. I always show them the movement when I need one replaced so there's no question.

The dealer here has not received any literature on it from Harley so they won't replace mine under warranty. It seems like Dealers in New Mexico, or at lest the one in Santa Fe, NM, don't get any of the service bulletins or recalls that everyone else gets. They looked at me like I was crazy for even mentioning that they are replaced under warranty. Guess I will have to solve the issue on my own or get a different gas cap. BS...

Go back to the dealer and show them the service bulletin number. Then they have to look it up and then they will see. I once owned a 2004 Mazda RX8 that the shops could not get my new tires balanced. it turned out to be a special mathematical formula used in conjunction with the balancing of the tire. The local Mazda shop had no idea that this existed. I got the procedure from a fellow forum member and printed out the service bulletin and it worked like a charm and the Mazda service center learned something new!

Same here a dealer(not mine) replaced mine free but I paid a few bucks extra and got a black one but I had shimmed and used paper gaskets on everything that could buzz,rattle or hum before putting my hand on the gas cap and the rattle stopped.
