KranKvent Crankcase Pressure Control Valve
Harley® engines have unique venting problems because of small crankease volume and a relatively long stroke. The Krankvent solves venting problems using high-tech materials combined with innovative design that improves performance and significantly reduces the build-up of pressure that can cause oil leaks and seepage at gasket joints particularly in the top end. Easily installed on all models.

Hayden Crankcase Pressure Relief Valve>
Tom Hayden, inventor of the M6 Primary Chain Tensioner, has now turned his engineering skill to controlling excess crankcase pressure in the Harley® engine The result is an ultra-compact design that utilizes a calibrated umbrella valve to reduce crankcase pressure and increase power.

Big Twin Breather Valves
Original Equipment plastic breather valves for all Big Twin models 1970 to present.

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.
