It's actually dual-purpose. First is to vent the crankcase as I described, recycling blow-by gases to the combustion chamber through the air cleaner and carburetor. The second to prevent water intrusion into the engine.
>From the Honda Common Service Manual: "A crankcase breather seperator is neccessary within the system to prevent moisture from entering the engine. Moisture vapor is not allowed to pass through the air cleaner and into the engine. Moisture is collected in a sealed crankcase collector tube. Periodic maintenance is to remove the tube plug and drain deposits into a suitable container, then reinstall the crankcase breather tube plug." -- You received this message because you are subscribed to the Google Groups "Nighthawk Motorcycle Lovers!" group.
