CRF Valve Cover Breather Performance Kit
Fits CRF250X, CRF250R, CRF450X and CRF450R.
This kit replaces the plugged off drain tube and hose that comes from your head cover and vents to the air box. It keeps only clean air being used for the intake which dramatically improves performance. It also eliminates the need to constantly drain the overflow tube as excess oil is vented out.
