Camshaft Kit - Easy Start - MR103 Gear Drive - Twin Cam '99-'06 (except '06 Dyna)

The S&S Cycle MR103 Gear Drive Camshaft Kit is designed to enhance engine performance and provide easier starting for Twin Cam models from 1999 to 2006, excluding the Dyna series of 2006. This kit features a specially engineered camshaft that initially reduces crank compression with a built-in centrifugal compression release, making start-up smoother and less effortful. Once the engine reaches higher RPMs, the compression release retracts, allowing the engine to run with full compression and maintain optimal power without sacrificing performance. This makes it an ideal upgrade for riders seeking increased power across the rpm range, especially between 2500 and 5500 rpm.
The kit includes all necessary components such as camshafts, a gearcover gasket, bearings, retaining ring, o-ring, thread lock, and detailed instructions for installation. It is designed as a bolt-in upgrade compatible with stock, un-ported heads, as well as S&S CNC ported heads, providing flexibility for different engine configurations. Made in the USA, the components are engineered for durability and performance, ensuring a reliable upgrade. Please note that installation requires checking for coil bind, valve-to-valve clearance, and valve-to-piston clearance to ensure proper operation. This kit is not suitable for models equipped with OEM compression releases, and proper installation is crucial for achieving the desired performance gains.

Designed for a straightforward installation, the S&S Cycle MR103 Gear Drive Camshaft Kit leverages a gear drive system to provide precise timing and smooth operation. The kit's compatibility with a variety of Twin Cam engines makes it a versatile upgrade option for enthusiasts looking to improve engine response and power output. Whether used for daily riding or performance applications, this camshaft kit offers a significant upgrade over stock components, especially for those seeking better throttle response and overall engine performance. The kit’s robust construction and detailed instructions ensure that mechanics and experienced DIYers can confidently undertake the installation, resulting in a reliable and high-performance engine setup.
