#Velocity stack socks free#

The conscientious mech checked my air filter (buried under the fuel tank) as it was easy to do so while working on the bike (hoping to up-sell me one?). Story moment: I had my bike into the stealership for a task that I didn't want to do myself. It worked well on 2 of my bikes which accumulated 100+k miles each. I like K & N because it is washable and only needs to be bought once. A filter mounted in a large still air box whose intake is kept well away from rain, rocks, and large crappola will function pretty well for a long time. A filter stuck on a velocity stack may have to deal with a lot more than just dust. An air filter may/may not work well due to how it is mounted. Especially when the farmers are working the fields.Ĭlick to expand.I politely disagree.

The air over a river isn’t miraculously free from dust. Ever look at the air filter of a chainsaw? And then I got around outboards, and there’s no filter at all. That engines would self destruct without them. I grew up thinking air filters were absolutely necessary. Way back in time, when we all had points gauges and magazines were printed on paper, hundreds of articles were written about sock filters and how they’d work ok on a Honda, but horribly on a Suzuki. Not all bikes/engines/carburetors/etc respond the same. The more the sock flows (the less it actually filters), the less adverse the impact on air flow. Look at rally cars and the propensity towards the likes of a large oval Piper filter on a bank of Weber DCOE’s and radius pipes. But not as actual filters.Ī well tuned, radius edged, velocity stack pulls air from all around, and works best with a large box filter that the horn sticks well into. As a screen for catching actual rocks, I’d say they’re reasonable. But, that also means they’re going to get clogged more quickly. Now you can make them more effective by oiling them. Heck, just look at the pictures you posted.

Hold them up to the light and look through them. For those tiny in-stack filters to actually flow, they can’t be very effective at filtering.
