This great looking Crankcase Breather solves a problem H-D has been plagued with since converting to their overhead crankcase breather in 1993; that is oil being ejected into the air cleaner through the breather system. With this breather, as oil-laden air condenses in the breather body, the excess oil now runs back down into the engine, rather than running into the air cleaner to be blown all over your bike. A cleaner setup for a clean machine!
