RevTech Adjustable Breather Valves RevTech Adjustable Breather Valves


Permit the engine builder to alter breather timing to match the displacement of the motor. Increasing the stroke or cylinder bore changes the total volume of the crank-case. If the breather is not modified, the cylinders fight the pressure build-up in the lower end that a stock breather cannot relieve. RevTech® offers an all-steel breather valve for Big Twins 1948-early 1991. It's designed to replace the stock steel or plastic breather valve and with its removable gear, permits you to dial in the the exact timing needed to ensure proper scavenging. Comes complete with selection of four different sized thrust washers.
