This S&S 124 cubic inch T124 low compression Long Block engine fits 2007-'16 HD touring bikes except Twin-Cooled models. Long Block engines do not include a fuel or ignition system, so If you already have a larger throttle body and EFI tuner, they can be used with this engine. The cylinder heads are specially machined to compensate for the longer cylinders so a stock length manifold or throttle body will fit perfectly, and the cylinder head breathers are compatible air cleaners designed for a stock engine. Stock non programable engine management systems should not be used because they are not designed for an engine this large. Engine features 4-5/8" stroke X 4-1/8" bore at 10.2:1 compression, S&S 585 gear drive Easy Start cams, S&S TC3 cam plate and oil pump, and wrinkle black powder coat finish that matches stock engine components. This engine has slightly less compression than our high performance T124 engine, making it more tolerent of variations in fuel quality, and a better choice for heavier vehicles. Installation requires an oil line kit which must be purchased separtately. Two year warranty. *T series engines are not compatible with HD Softail models* Not recommended for Tri-Glide or other three wheel models including conversion due to lugging nature of these bikes.
