gas cap issue
Saturday my wife and I went for a ride and we get to the end of our street and she says her bike (2018 Softail Slim) in making some type of noise, so we stop around the corner and I ride it around the block and it was definitely making some type of rattling noise up high but I couldn't quite pinpoint the source of the sound. So long story short we have a service manager ride it and he then switches out the gas cap under a warranty claim, seems there are a lot of gas caps that have been making a rattling noise, and actually if she had louder mufflers put on it would never have been noticed (she still has the original mufflers on). So if you have a rattling noise you can't quite figure out, ride it and push down on the cap to see if it stops the noise ( I was actually feeling around under the tank for something loose).

Yep. Known problem on some of the 2018 Softails. Fat Bob in particular. MoCo will swap em out for free, but who knows if the new ones are any better.....
A $10 aftermarket cap will fix the problem forever. Google "Rough Crafts gas cap".

They are not loose, they are 2 piece and the plastic inner piece breaks and rattles. I found they break faster if you overtighten them.

Been an issue even back in the Evo days. The ratcheting mechanism loosens up with use and the caps rattle. I usually replace mine every few years. They're cheap enough from Drag Specialties.
