The S&S Cycle Camshaft Kit - Easy Start (Part Number 106-5299) is engineered to improve starting performance and overall engine power for Big Twin motorcycles from 1999 to 2006, excluding Dyna models. This kit features a specially designed camshaft that initially reduces crank compression, making engine startups significantly easier. Once the engine reaches approximately 3000 rpm, the centrifugal compression release lobe retracts, allowing the engine to run with full compression without sacrificing performance or horsepower. This design ensures a smooth transition from easy starting to high-performance operation across a wide RPM range. The kit is ideal for engines with displacements between 88 and 124 cubic inches, and compression ratios from 9.0:1 to 10.5:1, providing substantial torque and horsepower gains especially in the mid to high RPM ranges. It includes all necessary components such as camshafts, gearcover gasket, bearings, retaining ring, o-ring, thread lock, and detailed installation instructions, making it a comprehensive upgrade for experienced technicians. Manufactured in the USA, this bolt-in kit requires the installer to check coil bind, valve-to-valve, and valve-to-piston clearances to ensure optimal operation. Designed specifically for models without OEM compression releases, this camshaft kit delivers enhanced performance, increased torque, and improved throttle response, making it an excellent choice for riders seeking to maximize their Big Twin's engine capabilities.
