Hello everyone, I've bought a pod style filter to replace my airbox in my bike. However I have realized that there is hose that runs from my engine back into my airbox. It bypasses the filter and I believe it to be for blowby gases. My question is this; If i replace my airbox with this filter what should i do about this pipe? 1) cap it off 2) leave it disconnected 3) modify a connection into the pod for it Edit; discovered it is a crank case breather hose..
