This kit includes S&S 4-1/8" bore pistons, big bore cylinders finished in wrinkle black powder coat, a dynamically balanced 4-5/8" stroke three piece flywheel assembly complete with S&S heavy duty connecting rods and intergal mainshafts, S&S 640 gear drive Easy Start camshafts, S&S chromoly steel adjustable pushrods, S&S premium tappets, S&S Super Stock 91cc cylinder heads. When installed the kit yeilds a 124 engine with a compression ratio of 11:1. 960 taller than stock, there are no frame clearance problems, and a stock EFI Throttle body will fit because the manifold mounting surfaces of the heads have been specially machined to fit a stock length manifold.
No fuel or ignition system is included. However, for the best results, a larger EFI throttle body, performance intake and performance exhaust are recommended. The EFI system must be recalibrated. Although not mandatory, we recommend adding an oil cooler to bikes ridden in warmer climates.The item "S&S CYCLE 124 HOT SET UP ENGINE KIT, 2006-17 TWIN CAM A, BLACK FINISH, 900-0568" is in sale since Thursday, October 24, 2019.
