Kuryakyn 9930 Kuryakyn Bluegrass Crankcase Breather Kit

• 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
