Fuel Cap

[Guest]

Hi all, scanned through the forum and haven't had much success with an interesting problem I have. My fuel cap is "loose" and rattles while riding. I thought for months I had forgotten to tighten something on the front end, checking, rechecking, torque wrench etc only to notice the cap moving 1 afternoon.
Anyone else had this issues? Is there a way to adjust it without just replacing it with a new one? I've looked around thinking perhaps I could just buy replacement gaskets for it, not......
Anyone else ever had this issue?

You sure that you got correct fuel cap and not a sorta fits generic replacement?

Its the correct cap, the handle broke off the original and I'm using one off one of the spare tanks I have. When I first started using this one all was good, then after a few weeks it started rattling.

There is generally a spring seat supporting the cap seal. They go rusty. Could it have broken up and is letting the cap sit too far down ?

[racerguy36]

I don't see any type of spring at all. I seems to fit into the filler hole flush to the top of the tank, once the tab is locked, the cap will still turn a bit.

Lift the rubber cap seal. Underneath there should be a thin metal disk thing supporting it like a large thin belleville washer. It provides the resistance as you push the cap closed and holds the cap up against the bottom of the filler neck.
