S&S Cycle Camshaft Kit - Easy Start for Twin Cam '07-'17 and Dyna '06 | Part No. 330-0299

Camshaft Kit - Easy Start - MR103 Chain Drive - Twin Cam '07-'17 | Dyna '06

The S&S Cycle Camshaft Kit - Easy Start (Part No. 330-0299) is designed to improve engine performance while simplifying startup procedures for Harley-Davidson Twin Cam and Dyna models. Featuring an innovative compression release mechanism, this kit allows for easier engine starting by temporarily reducing crank compression during startup. Once the engine reaches higher RPMs, the centrifugal retraction of the compression release ensures the engine runs with full compression, maintaining optimal power and performance without any loss. This makes it an ideal upgrade for riders seeking reliable starting and enhanced power across a broad RPM range. The kit includes all necessary components such as camshafts, gearcover gasket, bearings, retaining ring, O-ring, thread lock, and detailed instructions, all assembled in the USA for quality assurance. Designed as bolt-in replacements, these cams are compatible with stock un-ported heads and work exceptionally well with S&S CNC ported heads for increased airflow and performance. The camshaft kit is suitable for engines with compression ratios from 9.7:1 up to 10.5:1, providing increased power especially in the 2,500 to 5,500 RPM range. Installation requires careful checking of coil bind, valve-to-valve clearance, and valve-to-piston clearance to ensure optimal operation and longevity. Note that this kit is not compatible with models equipped with OEM compression releases, making it essential to verify your engine configuration before installation.
