As weird as it may sound, since I've had the bike, when I'm riding it its always sounded like its about to fall apart. It sounded like there was a nut with a washer and the nut wasn't completely tight and the washer would vibrate around.

Coming home the other day while riding I decided to tightening my gas cap one click while I was moving along and when I put my hand on it I was shocked that all of that noise has been coming from my gasp cap this whole time. And it's a lot of noise lol.

Any way I could dampen this? Do they have rubber inserts or something that could be placed around the opening by the threads?

 

dont know how to fix it but my 99 XLH has the same problem.

 

There was another thread a while back that addressed fixing this I think, but I have been unable to locate it- of course a new cap might fix it

 

My chopper does that at certain RPMs. I have the Aircraft ftyle cap though, I just got used to it I guess.

 

Ignore it. You know that it's nothing serious. My ignition switch cover makes a helluva a jingle. After locating the noise I now don't care because I know that it is not my motor turning to metal shavings. It's a Harley, they are meant to make ****ty noise.

 

is the cap loose in the tank or the shiny tin cover on top loose? If it's just the cover, either ignore it of wrap with a shop towel and give it a squeeze with a big pair of channel lock plyers in 4 places. ( like a pluse sign ) Not too hard though. That should help tighten it up, just not for too long.

 

Mine was vibrating to the point it was coming loose...strong odor of gas alerted me to that. The locking gas cap was the cure.

 

Why not lose the vibrating twist in cap and go pop up?

i have the same problem, i just popped the cover off the cap put a little bit of silicone in there and crimped it back on like zimbob says< careful if you take the cover off, its a little delicate and make sure not to plug up any of the venting.

 

i dealed with this problem 4 times already

the very top part of the cap is chrome, but its just a cover, its actually crimped around the bottom edge and over time vibration works it loose.

the noise is the thin cap cover vibrating over the body of the cap itself. but its actually really tight in the tank, you can try to crimp it back yourself, but your better off with a new one and yes it will do the same thing over time unless you somehow seal it with silicone from the inside, but then it might not vent anymore
