This crankcase vent replaces your dipstick and allow excess crankcase pressure to be released. This is especially beneficial on bikes that are enduring a lot of high RPM or for big bore builds. As crankcase pressure increase, it will not only rob your bike of running at full performance, however also increase oil temps quickly.

CJR recommends not running the exit portion of the vent cap.
