Crankcase Breather Reed Valve

The new-style Crankcase Breather Reed Valve is designed for optimal performance. Unlike traditional breather systems, this innovative valve does not rely on the crankshaft rotation to operate. Instead, it opens when the crankcase pressure exceeds the pressure in the cam chest, ensuring efficient airflow.

With its "on demand" functionality, the reed valves effectively manage air mass acceleration, which enhances overall performance and minimizes high-rpm oil carryover in engines that have marginal piston ring seal. This means a smoother ride and improved engine efficiency.

Installation is a breeze—there's no need to align timing marks or deal with rotating parts. Simply install, and you're ready to go!

Made in the U.S.A. for quality and reliability.
