Camshaft Kit - Easy Start - MR103 Gear Drive - Twin Cam '07-'17 | Dyna '06
The S&S Cycle MR103 Gear Drive Camshaft Kit (Part Number: 330-0303) is designed to enhance engine performance while ensuring easier startup for Twin Cam models from 2007 to 2017 and Dyna models from 2006. This kit includes precision-engineered camshafts, a gearcover gasket, bearings, retaining ring, O-ring, thread lock, and detailed instructions, providing a comprehensive upgrade for your motorcycle. Crafted in the USA, these cams are optimized for engines with a stock or slightly modified compression ratio up to 10.5:1, delivering increased power across a broad RPM range, especially between 2,500 and 5,500 RPM. The design features a compression release that reduces crank compression for effortless starting, which retracts via centrifugal force once the engine reaches higher RPMs, allowing the engine to run normally with full compression and uncompromised performance. These cams are bolt-in replacements compatible with stock, un-ported heads, and are particularly effective with S&S CNC ported heads, offering an ideal balance of improved power and ease of starting. Proper installation requires checking coil bind, valve-to-valve clearance, and valve-to-piston clearance to ensure optimal operation. Not suitable for models equipped with OEM compression releases, this kit promises a reliable, high-performance upgrade for experienced technicians seeking a seamless blend of start-up ease and enhanced engine power.
