Red Shift 786V2 Performance Cams for 1986-1990 EV XL® Sportster® and 4 Cam Offset Tappet Engines
These engines have off-center tappets (tappet centerline offset from cam shaft centerline).
786V2: This profile will allow tuning for increased power and torque over the previous 785 off-center design.
Increased valve train stability of this design requires extra-stiff pushrods but allows substantial reduction in valve spring pressure compared to other cams in this class.
Baisley Pro-Geometry rocker arms recommended (increase ratio for more lift).
