A number of Harley-Davidson bikes are equipped with a 96 or 96B.
Harley-Davidson builds a wide range of motorcycles, but it has several base engines that appear in multiple bikes. One of these is the 96Ci engine, which appears in bikes such as the Super Glide Custom FXDC and the Softail. Two versions of this engine–the 96 and 96B–are similar, but they are designated separately. The 96Ci was introduced in 2007, and it is still in production as of the 2011 model year.
Base Engine Design
The 96Ci engine is a 96-cubic-inch, air-cooled, twin cam engine with an electronic sequential port fuel injection (ESPFI) system. It uses push rods to control valve timing, and a tongue and fork connection is used to link the crankshaft to the connecting rods.
Bore and Stroke
The bore and stroke measurements on the Harley-Davidson 96Ci engine are 3.75 inches and 4.38 inches, respectively. Although some differences exist between the versions of the 96Ci engine, the 96 and the 96B have the same bore and stroke measurements.
The 96 and 96B engines follow the Harley-Davidson EVO line of engines, although one notable change is the oil pump. The oil pump in the 96 series engines is a twin-geroter oil pump rather than the external oil pump used for the EVO engines.
The 96B edition of the 96Ci motor produces slightly more power than the base model. According to Harley-Davidson, the 96 engine produces 92 pound-feet of torque at 3,000 rpm. The 96B produces an additional 1.7 pound-feet of torque at the same rpm.
The previous EVO engines use single-coil 14mm spark plugs. The plugs on the 96Ci engines are dual-coil plugs that measure 12mm. The 96Ci engine uses spark more efficiently than its predecessor.
The 96Ci strikes a balance between performance and efficiency. The 96Ci engine gets 34 miles per gallon in the city and 53 mpg on the highway. The B version of the engine achieves 35 mpg in the city and 54 mpg on the highway.
