This bolt-in cam set is suited for stock or mildly modified touring motorcycles and delivers stronger performance throughout the rpm range, with a focus on improved low- and midrange torque from 1,000 to 4,000 rpm. The kit is not recommended for engines with compression ratios of 10:1 or greater.\u003c\/p\u003e\u003cp\u003eThe gear-drive design reverses the rear cam’s direction of rotation, creating additional operating clearance between the cam lobes and allowing higher cam lifts. It also improves valve timing accuracy by eliminating timing chain lash and the looseness associated with the stock chain. Due to the inherent characteristics of gear drives, increased valvetrain noise may occur during operation.\u003c\/p\u003e\u003cp\u003eThis complete kit includes inner gears, outer gears, inner and outer bearings, gaskets, and installation instructions. Installation requires material removal from the inner surface of the stock gear cover, along with a hydraulic press and other professional-level tools. Cam bearings and gaskets must be replaced when installing the new cams, and S\u0026amp;S Cycle recommends using an adjustable pushrod and cover kit. The installer must verify coil bind, valve-to-valve clearance, and valve-to-piston clearance before the engine is operated.
