S&S Cycle 124 in. Big Bore/Stroker Hot Set-Up Kits

The S&S Cycle 124 in. big bore/stroker Hot Set-Up kits transform a stock Harley-Davidson® engine into a 124 in. monster. It includes: 4 1/8 in. bore pistons; big bore cylinders finished in wrinkle black powdercoat; a dynamically balanced 4 5/8 in. stroke 3-piece flywheel assembly complete with heavy-duty connecting rods and integral mainshafts; 640 gear drive Easy Start camshafts; chromoly steel adjustable pushrods; premium tappets; and Super Stock 91cc cylinder heads. When installed, the kits yield a 124 in. engine with a compression ratio of 11:1. Although the engine is .960 in. 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. If you ride a 2006 HD Dyna model, or a balanced or non-balanced Big Twin from 2007-17, these top-end engine rebuild kits are for you. Note: 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, S&S recommends adding an oil cooler to bikes ridden in warmer climates. S&S does not recommend compression ratios higher than 10:1 for Tri Glide or other 3-wheel models (including conversions) due to extra loads caused by the lugging nature of these bikes. Detonation and subsequent engine damage may result.
