Motor Specifications

A twin-cylinder 1449cc (88 cubic inches) engine, part of Harley’s “Evo” line, powers the 2003 Harley-Davidson Road King. The engine features two valves per cylinder; these overhead valves are pushrod-operated and equipped with self-adjusting lifters. Harley’s 2003 Road King gets its spark from a single-fire, map-controlled ignition system, which is breakerless and features a multiple advance curve matrix. The bike has a bore and stroke of 95.3 mm by 101.6 mm and a compression ratio of 8.8:1. The motorcycle’s air cleaner and filter touts an ESPFI-identifying embossed aluminum insert and pleated paper filtration. A dry-sump system with a spin oil filter keeps the motor lubricated. The entire motor is rubber mounted, which prevents frame members from snapping and fillings from loosening.
