    Default crankcase breather

    has anybody completely blocked off the crank case breather into the air box while doing the airbox mod and replaced the hose with a crank case breather filter instead? Also was there any bennefit?

    Yes I did.It idles smoother because you arent pulling in bad oily air from the crank case.That can foul out the throttle bodies as well.You will smell a little oil at idle but cruising, wont know the difference.
