S&S Cycle Crankcase Breather Reed Valve - 31-2100

Upgrade your engine's breathing efficiency with the S&S Cycle Crankcase Breather Reed Valve. This innovative design enhances performance and minimizes oil carryover, offering a significant improvement over traditional crankshaft-dependent breathers. Experience simplified installation and reliable operation with this high-quality, American-made component.

Description

The S&S Cycle Crankcase Breather Reed Valve utilizes a pressure-sensitive reed system that opens and closes "on demand." This eliminates the lag time associated with accelerating air out of the crankcase, which is a common issue with traditional breathers. By responding directly to pressure differentials between the crankcase and cam chest, the reed valves ensure optimal venting and prevent oil carryover, especially in high-rpm conditions where piston ring seal may be marginal. This results in improved engine performance and reduced oil consumption. The silver finish adds a clean look to your engine.
