 ====== One Way Breather Valve (77-85) ======
 The one way breather style system is more like a car PCV system. ((mrmom9r of the XLFORUM http://xlforum.net/forums/showthread.php?t=1204854&page=4)) Unlike an auto PCV, a Sportster has a faster acting type one way valve. \\

     * In L1982, a new style crankcase breather valve was used in production. \\ The breather valve kit (26909-79A), which is functionally more durable and quieter than the early style reed valve, will fit 1979-E82 models. \\ The late style breather valve incorporates a rubber umbrella valve attached to the base plate along with a larger diameter oil slinger washer. \\ The oil slinger washer is bigger (1-3/4" OD). \\ These parts, used together, will replace the early style reed valve assembly and smaller diameter oil separator washer. \\
