Beschreibung

+.030" oversize steel breather valve. Used to save worn or damaged crankcases. Okay for stock or high performance replacement. Note: JIMS has a +.030" breather hole reamer tool which is available as 978343. Note: that steel breathers require steel breather valve spacers. Plastic breathers require plastic spacers. Do not intermix steel and plastic parts. 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. Tech tip: The timing for S&S breather valves; only for late 77-99 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 by install
