2018 Fatbob gas cap rattles
#41
The cap on my ‘18 Deluxe started to rattle badly right after my 1000 mile maintenance. My dealer said that I’d need to bring the bike back in so that they could check it themselves before giving me a new one.
Then I remembered that I had an extra OEM one, new in box. I had bought a take off gas tank for my old XL1200X that I never ended up using. It didn’t come with a cap, so I had to order one through my dealer.
That was back in 2015, so the cap was at least 3 years old. I put it on the Deluxe, and it’s been fine so far.

I had to crimp the inner cap or whatever in a bit to reduce the rattle on mine but it's still there. But I think I have another rattle somewhere else in the front. I haven't narrowed it down yet. I'll have to get another cap to figure it out, which I was going to replace anyways. Mine pretty much rattled when I drove it off the lot I believe.

2018 Sport Glide, had the same problem. For the longest time I thought it was something in the top end and felt like an idiot when I realized what it was. The dealer said he'd replaced three in the last month and replaced mine, but said Harley would only replace it once. The new one is already rattling, so I'll try some of the fixes here. Thanks to everyone who has shared ideas - you've probably saved me $50! (Incidentally, it's surprisingly hard to find gas caps with dummy cap mates...)

I used a screwdriver to tap around the perimeter of the underside after reading this last night and it got rid of the worst of it (though this second one wasn't that bad yet - the first one was really loud). Before I got the first one replaced, I wrapped a thick piece of nylon cord under the lip of the cap when it was in place on the tank and that did the trick too, though it wasn't the most elegant solution. But yeah, once you hear it, you can't ignore it. I can't believe this silly, simple problem can't be fixed at the source.
