S&S™ introduce their first truly complete 124" T-Series engine. It all starts with their super strong crankcase, which has extra thickness in key stress areas built in. A Timken style sprocket shaft bearing gives extra strength and load capacity. Onto this strong foundation they added their flywheels, connecting rods, a .640 lift drive gear cams, their 4 1/8" bore cylinders and pistons, rocker arms and covers, and the electric compression releases. S&S™ also included their new oil pump. This pump replaces the separate oil pump, cams, cam support plate, bearing plate, bearings and gear cover of a stock Twin-Cam engine. This new oil pump incorporates a modified version of the gear drive cams, and actually uses the cam drive gear to pump oil to the engine and to scavenge oil from the cam chest. Instead of the decorative outer gear cover this oil pump system includes a functional show polished billet gear cover that support the outer ends of the cams. Engines are completed with either a Super G carburetor or S&S™ Variable Fuel Injection (VFI) module with manifolds and throttle body for fuel injected bikes. The VFI system also comes with a tuning software package, which contains fuel maps for the most common exhaust systems used in conjunction with both S&S™ air cleaner and the VFI tuned injection system. VFI engines are available for engines with stock Magnetti- Marelli injection systems from 1995 thru 2001 and for engines with the Delphi system that was mounted on 2001 Softail and on all 2002 till 2003 models. S&S™ VFI is not compatible with 2004 and later models. As there are different Induction Kits available for VFI equipped engines, you have to order the style of your choice separately. When a carbureted engine is bought the S&S™ Intelligent Spark Technology (IST) ignition module is an option to consider as engines with IST ignition are covered with an extra one-year warranty, so you get a total 2-year warranty. S&S™ is sure the IST ignition will protect the engine for damage due to detonation. Also the "break in rev. limit" is activated on IST modules sold on complete engines. This means that the maximum RPM will increase after a certain amount of running hours. There are two different motor mount styles of 124CI T-Series engines available. The first type is designed and intended for installation in a stock Harley- Davidson Twin-Cam Chassis. This engine will bolt directly to the stock transmission and engine mounts of chassis designed for stock unbalanced Twin-Cam engines. A balanced T-Series style engine is not available at this time. The second type of T-Series engine is machined with an Evolution style rear motor mount and may be installed in a stock or aftermarket Evolution style chassis.

S&S™ TÜV APPROVED 124CI T-SERIES ENGINE These carbureted engines are basically the same as S&S™ unrestricted 124CI T-Series engines, with the same super strong crankcase, Timken style sprocket shaft bearing, gear driven cams, 4 1/8” bore cylinders and pistons, rocker arms and covers, and the electric compression releases. These engines are completed with S&S™ IST ignition, a Super G carburetor and S&S™ teardrop style air cleaner. They use different cam shafts, a special carburetor, air cleaner and intake restrictions as the S&S™ unrestricted engines to get them into comply with the latest TÜV emission standards. Engines are available for installation in a stock Harley- Davidson Twin-Cam Chassis, or Evolution style rear motor mount for installation in a stock or aftermarket Evolution style chassis. A balanced version as used in Softail models, nor a fuel injected version is not yet available.
