S&S Crankcase Reed Breather Valve For Harley Evo Big Twin

Features:

  • New style breather is not dependent on the rotation of the crankshaft to make it open and close
  • Reeds open when the pressure in the crankcase is greater than the pressure in the cam chest and close when the pressure in the cam chest is equal to or greater than the pressure in the crankcase
  • By opening and closing "on demand" the reed valves automatically compensates for the lag time associated with accelerating the mas of air as it is forced out of the crankcase
  • Increases performance and stops high-RPM oil carryover
  • Installation is fast and simple, no aligning timing marks or rotating parts
