Gear drive uses less engine power to operate and improves valve timing accuracy over stock chain drive camshafts. Dynamometer comparisons show gains of 4 horsepower over chain drive camshafts. Can be installed on both carbureted and fuel injected models (exc. 2006 Dyna). Bolt-in cam first introduced in 2000. More torque for all around riding with stock comp. ratio and heavy bikes. Similar to #23 cam for EV80 (1700-5200 RPM). NOTE: Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance. NOTE: Sold as cams only, inner and outer gear kit and installation kit must be purchased separately.
