Hello Lupo municipality, to me is a Lupo 6X MKB AUC which I just set up a bit. I have a question about crankcase ventilation. Below the air filter box is a vacuum valve. The hose comes from the KGE. On the other side the connection is open. Where should this connection normally go? At the throttle valve unit sits a piece of hose that is closed with a blind plug. Is this possibly the right connection? AND: Why do you do something like this…? Thanks & Greeting Ciwa
