S&S Crankcase Breather Reed Valve (Standard) for 1993-1999 Big Twins (31-2096)
S&S - CRANKCASE BREATHER REED VALVE
- Made in the U.S.A.
- By opening and closing "on demand," the reed valves automatically compensate for the lag time associated with accelerating the mass of air as it is forced out of the crankcase, increasing performance and stopping high-rpm oil carryover in engines with marginal piston ring seal.
- Installation is fast and simple; no aligning timing marks, and no rotating parts.
- New-style breather is not dependent on the rotation of the crankshaft to make it open and close; instead, reeds open when the pressure in the crankcase becomes 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.
- Available in standard or +.030" oversize.
- Sold each.
