Breather valves and the precision shims that set them up — components that regulate crankcase pressure and keep the V-twin venting correctly. We stock Jims and Kraus, fitting Big Twin and Sportster engines to help prevent oil leaks and hold a consistent crankcase vacuum. Correctly shimmed breather assemblies matter most during an engine rebuild or performance upgrade on Softail, Dyna, Touring, and Sportster motors. Set the endplay right and they'll seat properly.
