Thread: Keyless Gas Caps

I've had two Vortex caps, one would leak on track with a full tank, one didn't.

Seemed vented, never had any issue like that.

Marchesini used to make a really nice one, I'd guess they probably still do.

Vortex on the RC and it hasn't leaked. The venting should be under the cap. A hole will there that runs to a vent tube running out the bottom of the bike

TIA

If you're not going to go endurance racing, what's the benefit?

It often falls closed on me. It barely stays open, the wind blows it shut, then I end up with spilled gas, which wasn't an issue until I put on race glass with a belly pan. I'm sick of emptying it out. I tape the damned thing open, but then the tape will suddenly let go, and there's that spilled gas problem again.
It would be nice to gas up at the track without spillage.

For me at the track it is convenient to not need a key when adding gas. Plus it saved a gram or two (iKidding)

Can't remember the brand, but the local shop gave me this one to replace my Vortex.

Happy with it and it does lock down, although its tricky to get the tab to sit flush sometimes.

Vortex here. No leaks, no issues and do not need a key to open.

You know, I'm thinking about it, IIRC you are right. I seem to remember it releasing pressure when I'd open it.

Thanks, well, I certainly don't want my gas tank to implode! Maybe I'll have to keep taping it open, or look into the Slingshot one...

Motorcycle Repair: Overflowing gas tank, suzuki 1100, tank vents

Read the below explanation on newer bikes. That is how my RC is and I am betting so is your zuk. It is not the cap that is vented anymore. There is a vent below the cap assembly that runs into a tube that come out the lower (on Honda's near the kick stand).

Keyless gas caps?

Oh ... I thought you said assless chaps ... I was going to let Baketech know that his expertise was needed over here ...

Some of the less expensive caps not only aren't vented, but tend to get stuck closed (galling?) and also can be tough to get started without cross-threading when screwing closed. Haven't had that problem with the one I picked up.

Sent them an email and they confirmed it's vented. They look nice, and are a bit less expensive than others like Vortex. I may go this route, thanks for the info.

Although, I was told that the Vortex and stock caps aren't vented, as the venting is accomplished through the gas overflow tube. Not sure I buy that since that hole is on the outside of the hole that the cap securely fits in with a gasket.
