Bluegrass Breather Kits Catch Tank

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. Venting the crankcase to this Bluegrass Catch Tank to capture the expelled oil will keep the mess from your bike.
