The S&S Cycle Easy Start Camshaft, part number 106-4840, is designed to facilitate effortless engine startup for Twin Cam models built between 1999 and 2006, excluding the ’06 Dyna. This camshaft features a specialized compression release that reduces initial crank resistance, making engine starting easier and less strain on the starter system. Once the engine reaches approximately 3,000 rpm, centrifugal force retracts the compression release lobe, restoring full compression and ensuring the engine runs smoothly without any loss of performance. This design maintains optimal power output across a broad operating range, especially between 3,000 and 6,000 rpm, providing a balanced combination of ease of starting and high-performance operation.
The camshaft is compatible with engines ranging from 95 to 110 cubic inches, with compression ratios between 10.5:1 and 11.5:1. It is engineered with high-lift springs and requires adjustable pushrods for proper installation. The product is made in the USA and is intended for use on models without OEM compression releases. Proper installation involves checking coil bind, valve-to-valve clearance, and valve-to-piston clearance to ensure optimal performance and longevity. This camshaft is ideal for riders seeking enhanced starting capabilities without sacrificing engine power or efficiency, backed by the quality and durability associated with S&S Cycle products.
Overall, the S&S Cycle Easy Start Camshaft provides a reliable solution for easier engine starts, tailored for modified or stock Twin Cam engines, ensuring smooth operation and durable performance across a wide RPM range.
