Next-generation crankcase breather: a crankshaft-independent check valve that opens only when crankcase pressure exceeds timing-case pressure to vent air at the right moment. Optimized performance, no more oil leaks. Quick installation—no alignment or rotating parts. Made in the USA.
The new-style breather operates independently of crankshaft rotation for its opening and closing phases, while the reed valve opens only when the pressure in the crankcase exceeds that of the timing case.
Thanks to on-demand opening and closing, the valves automatically compensate for the delay caused by accelerating the mass of air expelled from the crankcase, which improves performance and eliminates oil leaks.
Installation is quick and simple, with no alignment required and no rotating parts.
