Description
If you’re running a high-rpm engine with marginal piston ring seal, oil carryover into your cam chest is costing you performance and creating maintenance headaches. The S&S Cycle reed valve solves this problem by automatically compensating for air mass acceleration in the crankcase, eliminating the lag time that stock breathers can’t handle. You’ll see cleaner combustion, reduced blow-by, and the kind of reliable operation that separates dialed-in engines from the rest.
