S&S Cycle Special Application Crankcase For Harley EVO 1984-2000

S&S Special Application Crankcase

This kit is designed and fitted for high performance engines with cylinder bore anywhere between 4" and 4-3/8".

Features

• Cam chest is relocated outward .250" which allows crankcases to handle larger cylinder bore sizes
• Relocated cam chest oil pick up maximizes gear case scavenging and nearly eliminates oil carry over at sustained high speeds
• Machined to accept the stock oil filter assembly used on 1992-99 big twins
• A ported breather passageway and a machined breather window permits the air and oil mist to flow from the flywheel cavity to the cam chest of the engines with minimal restriction
• Crankcase venting can be accomplished via two crankcase breathers, the cylinder heads, or both however, S&S recommends using both crankcase breathers for larger engines than 95"
• Clearanced for strokes up to 5"
• Machined for installation of a crank position sensor. This allows the case 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
