So I'm running airbox with no lid right now. Main is 270, needle 2nd notch from top. 2 turns out on air screws.
It's not perfect, I think I need a 260 main. Runs good, but bogs down after having a load on it for a bit.
My airbox seems to get lots of sand in it, and filter gets filthy after one trip. so I'm thinking I might put lid on. If so how many sizes you think I should expect. I think I should go to a 240... Think I'm close, or is it going to make these pipes run like dog shit?
