Harley-Davidson 92500073 Screamin' Eagle Milwaukee-Eight Engine Stage IV Kit 114 to 117CI Screaming Eagle

KIT,PWR PRFM UPGR,117, STAGE 4Stage IV

This Stage IV Kit was developed to deliver maximum horsepower from the Milwaukee-Eight engine

- all the way to the redline. The system-matched combination of larger displacement cylinders, free flowing CNC-Ported cylinder heads and a cam with the highest available valve lift are the starting point to building the perfect engine for the performance junkie. Designed for a high level of flexibility, this package is ideal for riders who like to comfortably cruise at lower rpm but still have plenty of arm-pulling acceleration when you whack the throttle. Kit includes CNC Ported Cylinder Heads with Performance Valve Springs, 64mm Throttle Body, High Flow Injectors (5.5g/s), 4.075" Bolt-On Cylinders, Forged 11:1 High Compression Aluminum Coated Pistons and Rings, SE8-515 Cam, Cam Bearing Upgrade, High Performance Tappets, Multi-layer Coated Head Gaskets, High Capacity Clutch Springs (1200N) and most necessary gaskets and seals. For '17 and '18 Touring models, installation of oil pump cover P/N 62400206 is recommended (sold separately). All models require ECM calibration with Screamin' Eagle Pro Street Tuner for proper installation. See Dealer for details.
