Beschreibung

With steel breather valve spacer set for correct end play. High quality steel breather valve for use as stock or high performance replacement. Note: S&S breather valves come with elongated breather holes to increase the duration of the vacuum; allowing more oil to be drawn from the cylinder heads. This has no disadvantage in any model year; either stock or Big Inch motor. Note: A .030" oversize breather is available to save worn or damaged crankcases as 531238. A JIMS breather hole reamer (MCS 978343) will ream the damaged hole to +.030" so a +.030" breather can be used. Tech tip: The timing for S&S breather valves; only for late 77-84 Shovel and 84-99 Evo Big Twin models; has been changed by S&S in the year 2000. This is done to improve oil scavenging and reduce oil carry-over in high performance / large displacement engines. Old opening was at TDC and closing at 65� after BDC. New opening is 17� after TDC and closing at 82� after BDC. The old timing specification can be obtained
