S&S Cycle Engine Case – +4.000″ Bore – Special Application – Evolution Big Twin

Description

• Product Description
• Vehicle Fitment

• • Designed for high performance engines with cylinder bores 4.000″
  • Cam chest is moved outward 0.250″ to allow crankcases to handle large cylinder bore sizes
  • Clearanced for strokes as long as 5.000″
  • Relocated cam chest oil pick-up increases gear case scavenging and virtually eliminates oil carry-over at sustained high speeds
  • Machined to accept the stock oil filter assembly used on ’92-’99 Big Twins
  • 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
  • Crankcase venting can be achieved via two crankcase breathers, the cylinder heads, or both; S&S recommends using both crankcase breathers in engines larger than 95″
  • Deck height is 5.875″
  • Made in the USA

  Notes

  • Machined for installation of a crank position sensor which allows the cases to be used in EFI applications and also allows easy installation of S&S IST Ignition and VFI Fuel Injection; a plug kit is included for applications that do not use a crank position sensor.
  • All S&S crankcases manufactured after June 1, ’08 do not have case interlock groove and ring and do not use case alignment studs. Case mating surface is flat, and cases are aligned with alignment dowels.
