(OEM 26318-88A) 1983 SPORTSTER OIL PUMP DRIVE GEARS 750586 Standard diameter 750587 +.030" oversize Patent pending reed valve crankcase breather from S&S that really helps to resolve oil carry over problems in Evolution Big Twin engines. Unlike the rotary breather valve that has been used in Big Twin engines since the 1930's, the S&S crankcase breather reed valve is not dependent on the rotation of the crankshaft to make it open and close. Therefore the opening and closing times are not determined by crankshaft position. Instead, the reeds open when the pressure in the crankcase becomes greater than the pressure in the cam chest. The reeds then close when the pressure in the cam chest is equal to or greater than the pressure in the crankcase. The difference in the way these breather valves function is important because the ideal breather timing actually changes with rpm and the condition of the engine. 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. This is most significant at high rpm when the time available to get the air out is the shortest. In addition, "on demand" operation allows reed valves to accommodate greater amounts of compression blow-by. Installation of the S&S crankcase breather reed valve has actually stopped high rpm oil carryover in test engines with marginal piston ring seal. The breather reed valve replaces the standard rotary breather valve in Evolution Big Twin style engines. Installation is fast and simple. Remove the original breather gear and insert the new S&S reed valve assembly into the breather valve cavity. No aligning timing marks and no rotating parts. The S&S crankcase breather reed valve can be used to replace the stock style rotary breather valve in engines with minor breather cavity damage, and there is a +.030" oversized reed valve for engines with heavily damaged breather bores. Fits all 1993-2000 Evolution Big Twin engines. 1979 S&S REED VALVE CRANKCASE BREATHER FOR EVOLUTION BIG TWIN 781034 Fits K, KK, KH, KHK and Sportster 1952 thru 1966 (OEM 26203-52E) 781033 Fits 1967 thru 1976 Sportster (OEM 26204-67) 781036 Fits 1977 thru 1985 Sportster (OEM 26204-75) 710632 Matching Colony oil pump mounting hardware kit, chrome allen head screws 781037 Fits 1986 thru 1990 Sportster (OEM 26204-86) 781035 Fits 1991 to present XL Sportster and Buell thru 2001 (OEM 23204-91A, 26204-98) 710633 Matching Colony oil pump mounting hardware kit, chrome allen head screws Completely assembled perfect reproductions of the OEMoil pump as found on all Sportster 1952 to present. 1982 VTWIN MFG.
