The S&S CYCLE Camshaft Kit Easy Start (Part Number 106-5289) is designed to enhance the performance of Harley-Davidson Big Twin models from 1999 to 2006, excluding the 2006 Dyna. This kit features a unique compression release system that simplifies engine startup by temporarily reducing crank compression. Once the engine is running and RPM increases, the centrifugal mechanism retracts the compression release lobe, allowing the engine to operate with full compression and optimal performance. This design ensures a smooth start without sacrificing overall power or efficiency.
The camshaft kit is optimized for use as a reliable, high-performance upgrade suitable for Softail and Dyna models, but it can be installed in any Big Twin engine. It provides significant low-end torque and horsepower, delivering the strongest performance between 1,500 and 5,000 RPM. The kit includes all necessary components for installation: camshafts, gear cover gasket, bearings, retaining ring, O-ring, thread lock, and comprehensive instructions. Made in the USA, this kit offers a bolt-in installation process for experienced mechanics or enthusiasts.
Attention to detail is essential during installation. The installer must verify coil bind, valve-to-valve clearance, and valve-to-piston clearance to ensure optimal operation and avoid engine damage. This camshaft kit is not suitable for models equipped with OEM compression releases and is not recommended for engines with compression ratios of 10.0:1 or higher. With its robust design and ease of use, the S&S CYCLE Easy Start Camshaft Kit is an excellent choice for riders looking to enhance their Harley-Davidson Big Twin's performance while maintaining reliable cold-start operation.
