The banjo fittings and chrome tubes route the vented gasses upward so gravity can keep any expelled oil droplets in the engine. The vent line can be run up and out, or the optional catch tank is available for those who would rather vent to a closed container.

• Engines that vent crankcase through the cylinder heads also expel oil through the same passages; venting directly into the air cleaner can result in an oily mess on the side of the bike
