Camshaft Kit - Easy Start - 551 Gear Drive - Twin Cam '07-'17
The S&S CYCLE Camshaft Kit - Easy Start is designed to facilitate effortless engine startup on Twin Cam models from 2007 to 2017. Featuring a specialized compression release mechanism, this kit reduces crank compression during starting, making it easier to fire up your motorcycle. Once the engine reaches higher RPMs, the centrifugal retraction of the compression release lobe allows the engine to run normally with full compression, ensuring no loss of power or performance. This innovative system is optimized for 88", 96", and 103" to 106" touring bikes equipped with slip-on mufflers and a compression ratio of 9.0:1. It is a bolt-in replacement compatible with stock or mildly modified touring models, providing a straightforward upgrade that enhances low-end and midrange torque. The kit includes camshafts, gearcover gasket, bearings, retaining ring, O-ring, thread lock, and detailed instructions, all built in the USA for quality assurance. This product significantly improves throttle response from idle to 4000 RPM, delivering stronger acceleration and smoother power delivery across a broad RPM range. It’s important to note that this kit is not recommended for engines with compression ratios of 10.0:1 or higher, and installers should verify coil bind, valve-to-valve, and valve-to-piston clearances before installation. Compatible with stock pushrods, lifters, and springs (unless specified otherwise), the S&S CYCLE Camshaft Kit - Easy Start offers a reliable upgrade for riders seeking enhanced torque and easier engine starts without sacrificing overall performance or requiring extensive modifications.
