So I know there's tons of posts on here about deleting the airbox. Mine method isn't all that much different other than I'm mounting the pod filter directly onto the throttle body. More on that and pics later when the filter shows up in the mail. But for the time being I'm removing the rest of the bits. I bought an sas blanking plate, the dongles, and a crankcase breather filter. But I'm left with the breather on top of the head. The purple arrows show the vacuum hose going from the head breather to the chamber in the frame. The yellow shows where there was a vacuum line to the now discarded airbox. Theres a second nipple below that one which had a vacuum line going to another part of the sas system that was discarded. All that being said, the obvious option in my head is to buy another breather filter similar to the crank case to fit onto the head rather than plugging the exposed points on the frame chamber. Any input on why that would or wouldn't work is appreciated.

Dont! Please put that airbox back in. The airbox provides "still" air ... that means no turbulence. W/O airbox the engine is subject to the whims of your bike at speed - pressure at times and then vacuum other times. The only place I've seen a benefit of a removed box is in the calm spaces of a dyno room ... not the real world. Trust me I have ported hundreds of heads and spent way too many hours in a dyno room. Believe it or not the factory has a bit of a clue to what they build. Replace filter with oiled gauze replacement ... that's it.

I guess some just insist on having less horsepower? Oh well, everyone has the right to make a statement and it's a free country.
