Kelsey, I have your basic Head/shim/piston kit, Not ported yet (maybe next year) I was wondering what baffles do you remove in the airbox...upper horn or the inner tubes?? Thank you Nick

If it is a DPM model.. you may want toleave the airbox together. If it is non DPM, then I would remove everything inside.

I would consider check the jetting after any modification to your air box. Take a spark test and maybe you would want to got up a size.
