Features:

• Simple yet effective way to keep the oil inside the engine or at least contained
• Banjo fittings and chrome tubes route the vented gasses upward so gravity can keep any expelled oil in the engine
• We recommend venting the crankcase to the open air by hiding the vent line up and out of sight beneath the tank
• Optional catch can 401 722 is available for those who would rather vent to a closed container
• Works with all Mikuni carbs on 1993 99 Evo Big Twin and 1991 06 Sportster models
• Unfortunately, almost all Harley Davidson engines that vent the crankcase through the cylinder heads also expel oil through the same passages.
• Venting directly into the air cleaner, especially a free flowing air cleaner, often results in an oily mess on the side of the bike.
• The banjo fittings and chrome tubes route the vented gasses upward so gravity can keep any expelled oil droplets in the engine where they belong.
• It is recommended venting the crankcase to open air by running the vent line up and out of sight beneath the tank, but an optional catch tank is available and sold separately for those who would rather vent to a closed container.
• Notes Fits 1993 , 1999 EVO Big Twin with Mikuni HSR series carburetor, 1991 , 2013 Sportster models with carburetor or EFI.
