So.... now I have installed my ProDesign pro flow kit w/K&N filter. The instructions say to pull the crank case vent hose out @1/2 inch. This allows the K&N filter to fit, but will dirt get into my crank case through this hose? I think the flow of air comes out of this hose, but now there is no negative pressure (vacuum) from the motor. I'm sure some gasses may come out as the piston moves down, but will it draw in dirt as it moves up? Also, no airbox lid. I'm open to any thoughts, opinions, experiences, or flat out correct answers. Maybe a breather filter should be placed on the hose.... or maybe I'm just paranoid! What has everyone done with this hose?
