This kit is designed to deliver a significant boost in low-end and midrange torque, enhancing your riding experience from idle to 4000 rpm. Experience improved performance and responsiveness with this high-quality camshaft upgrade.\u003c\/p\u003e\n\n  \u003ch2\u003eDescription\u003c\/h2\u003e\n  \u003cp\u003eThe S\u0026amp;S Cycle 551 Easy Start Camshaft Kit is engineered for optimal performance in 88\", 96\", 103\", and 106\" Harley-Davidson Touring bikes. This kit features an innovative design that initially reduces cranking compression for easy starting. Once the engine starts and RPM increases, the compression release lobe retracts centrifugally, allowing the engine to run at full compression without any performance loss. The 551 cam is a bolt-in solution for stock or mildly modified Touring models, providing a substantial increase in torque where you need it most. This kit ensures reliable performance and ease of installation, making it an excellent choice for enthusiasts and professionals alike. The S\u0026amp;S Cycle 551 Easy Start Camshaft Kit is designed to work with slip-on mufflers and 9.0:1 to 9.9:1 compression ratios using a stock starter.\u003c\/p\u003e\n\n  \u003ch2\u003eFeatures \u0026amp; highlights\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eEasy Start design reduces cranking compression for effortless starting.\u003c\/li\u003e\n    \u003cli\u003eOptimized for 88\", 96\", 103\", and 106\" Harley-Davidson Touring models.\u003c\/li\u003e\n    \u003cli\u003eDelivers a significant boost in low-end and midrange torque.\u003c\/li\u003e\n    \u003cli\u003eBolt-in installation for stock or mildly modified engines.\u003c\/li\u003e\n    \u003cli\u003eImproves performance from idle to 4000 rpm.\u003c\/li\u003e\n    \u003cli\u003eMaintains full compression and performance after startup.\u003c\/li\u003e\n    \u003cli\u003eMade in the USA.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eBrand: S\u0026amp;S Cycle\u003c\/li\u003e\n    \u003cli\u003eGrind: 551 Series\u003c\/li\u003e\n    \u003cli\u003eType: Chain\u003c\/li\u003e\n    \u003cli\u003eIntake Open: 17°\u003c\/li\u003e\n    \u003cli\u003eIntake Close: 19°\u003c\/li\u003e\n    \u003cli\u003eIntake Duration: 215°\u003c\/li\u003e\n    \u003cli\u003eIntake Lift: 0.550\"\u003c\/li\u003e\n    \u003cli\u003eIntake Lift at TDC: 0.178\"\u003c\/li\u003e\n    \u003cli\u003eIntake Lobe Centerline: 91°\u003c\/li\u003e\n    \u003cli\u003eExhaust Open: 41°\u003c\/li\u003e\n    \u003cli\u003eExhaust Close: 17°\u003c\/li\u003e\n    \u003cli\u003eExhaust Duration: 237°\u003c\/li\u003e\n    \u003cli\u003eExhaust Lift: 0.550\"\u003c\/li\u003e\n    \u003cli\u003eExhaust Lift at TDC: 0.170\"\u003c\/li\u003e\n    \u003cli\u003eExhaust Lobe Centerline: 102°\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch2\u003eImportant to know\u003c\/h2\u003e\n  \u003cp\u003eThis kit is not recommended for compression ratios of 10.0:1 or greater.
