🏍️ Enhance Performance & Preserve Engine: 10 Pack Motorcycle Gas Cap Breather Tube Vent - Universal Fit for CRF, XR, CR, Quads & Off-road Bikes (Black-Blue) Review

It's just ventilation as I expected. But they are tight and there are no leaks. They look good and you get 10 of them for a good price. I really like her.

Looks good but doesn't work as it should. They have a vent that allows vapor or liquid to pass in either direction. If the motorcycle tips over, they will spill fuel.

They work great with our KLX110. I thought it would be handy to have a few spares, but they haven't come loose in the hours of driving (and a few spills) since I installed them, so the spares may never be needed.

I honestly don't know anything about these items. I just bought them for my brother who is interested in motorcycles. He asked me to buy them so he could have them. He told me they were good quality and worked as they should.

First I checked it with air, then I poured water into my mouth thinking that I need liquid. No, it will come immediately. Solution 2 of 10 does not work with air. It's like there's not even a ball in the cap. All others you can shake and hear the ball inside.

Out of 10 pieces, all 10 react very differently in the test, but the most disappointing thing is that one-sided air passage is assumed, but which work better (maybe 2 out of 10 coming) a free pass in one direction and a second pass in the other direction is not very close. Maybe it works for others, but for my needs it doesn't work as expected

I should have thought that at such a price this was rubbish. I was skeptical and made the cut. You are better off if you just have a non-vented hose as this is no different. It does not include a check valve (one-way valve) to allow gases to escape from the fuel tank but not allow dirt or water to enter. It hasn't. All there is is a tank decoration with a hole.

Wouldn't use them on a dirt bike as gas can leak onto your nuts. These are nice pipe ends, but 8 out of 10 are vented both ways to allow fluid to escape and the other 2 I either had to drill to work either way or throw them away. You guess which one. Still got 3 stars because they were good enough to let air into the gas tanks, my GoPed and the generator.
