The cap i ordered does not allow pressure that builds up in tank to escape through the vent. Only air to enter as fuel is used. Pressure tends to build up a bit in tank as weather heats up and causes floats to not seat and bowl to overflow leaking gas onto engine.

This Gas cap fit perfect, looks great too. If you put the breather tube on properly, it won't come off. Much better cap than the stock one.
The cap was a perfect fit except the breather hose wouldn't stay on. switched it out with a softer type hose & no more problems
It was a very good fit on my cr250r it is a bit heavy but mine doesn't keak. I put a dab of super glue to keep it from coming off
a decent overall product but its extremely heavy and the vent on both of my did not vent and i had to replace them with a different style vent. but a very stylish cap
Overall this product definitely makes your ride look good. I gave it a 4 out of 5 because the threads take awhile to lineup but it still is a good tight fit. This was on my yz 125
Purchased after getting water in my tank probably from that stupid stock hose they put on a stock cap. It is a gas cap and the balck cap looked good, not alot to say about a gas cap?
Bought this for my 2006 SE blaster,Tanium. looks awesome on the black tank, read review, Mine does NOT leak, and the vent tube after I put it on, it stayed on. Just looks amazing.
Along with new red bars, this (red) gas cap gives my Raptor Rosie a clean look. She's all done up with a fresh coat of lipstick. Mmmm Mmm
This gas cap is great the one way valve eliminates the long vent hose. If that wasent enough it also makes the tank look refined. I love the look of the aluminum as well!!
Doesn't fit good, leaks and for the money you would think this product would be better, the only thing that's good about this gas cap was the look!!!
They gave this gas cap the right name. Rock solid and well worth the money. throw one on your bike and forget its there.
i bought this and the vent stem fell right off and i lost it... but before i lost it the thing leaked gas everywhere and stripped my gas tank no matter how carefully i put it on...dont waste ur money
I bought this cap for my 03 crf 450 and it leaks gas but my brother tried it on his 07 crf 450 and it doesn't leak.
Looks good and screws on good, but leaks fuel all over out of the vent hose. Over all would'nt recommend buying this product to anybody.
The first day I had it on, the air vent tube kept falling off and just the motion of the bike made it leak. So I just went back to the stock cap. Don't waist your money on this gas cap!
My first ride the hose came out and was lost it was pouring down rain> I was worried the rain would enter the tank.
Paid good money for this Rock Gas Cap and the hose came out on some rocky hills.
I got this gas cap for my yfz for christmas because i had some extra money left over and im now wishing i would have spent a little bit more money! I go for performance over looks and even though this cap looks good it leaks. If ever you have to prop your bike on its rear tires you will have a leak coming from the cap. So if i could do it again i would spend a bit more and get one that doesnt leak. Im kinda wishin i kept my OEM cap!
i bought this gas cap for my 250 and it looks awesome. it adds extra bling and is light and strong. but becareful, if u roll ur quad, set it up immediatley because gas will start to leak from it.
