# S&S Cycle 92-99 BT w/ 4in Bore Special Application Crankcase - Natural

A ported breather passageway and a machined breather window allows the air/oil mist to flow from the flywheel cavity to the cam chest of the engine with the least possible restriction

-   A ported breather passageway and a machined breather window allows the air/oil mist to flow from the flywheel cavity to the cam chest of the engine with the least possible restriction
-   Machined for installation of a crank position sensor which allows for use in EFI applications and also allows easy installation of S&S IST® Ignition and VFI Fuel Injection
-   Crankcase venting can be achieved via two crankcase breathers, the cylinder heads, or both! We recommend using both crankcase breathers in engines larger than 95"
-   Relocated cam chest oil pick-up increases gear case scavenging and virtually eliminates oil carry-over at sustained high speeds
-   Cam chest is moved outward .250" to allow crankcases to handle large cylinder bore sizes
-   Machined to accept the stock oil filter assembly used on 1992-'99 big twins
-   Clearanced for strokes as long as 5"
