When thepistons travel downward in the cylinders, pressure in the crankcase below the pistons increases. This pressure causes the reeds to open,allowing the air and oil mist in the crankcase to escape into the cam chest. When the pistons change direction and begin traveling backupward in the cylinders, a vacuum is created in the crankcase. The vacuum causes the reeds to close, preventing air from entering thecrankcase. The effect is that a slight vacuum is maintained in the crankcase, and oil scavenging is greatly improved.MSRP$21.95OPTIONS• Available in standard size or +.030" for use in engines with damaged breather boresMSRP$108.95MSRP$85.95NOTEMSRP$3.75$3.75$3.75$3.10$3.75$3.75$3.75$2.60The crankcase reed valve should not be used in 1984 to 1992crankcase breathing engines.
