Once the engine reaches higher RPMs, the compression release lobe is centrifugally retracted, allowing the engine to operate with full compression and maintain optimal performance. This feature is particularly beneficial for vehicles with 95\", 96\", 103\", and 110\" engines that have compression ratios ranging from 10.5:1 to 11.5:1. The camshaft is engineered for high-performance applications within the strongest RPM range of 3000 to 6000 rpm, providing reliable power delivery and smooth operation. Made in the USA, this camshaft requires high-lift springs and adjustable pushrods for proper installation and performance. It is important for installers to verify coil bind, valve-to-valve clearance, and valve-to-piston clearance before installation to ensure proper fitment. Please note that this camshaft is not suitable for models equipped with OEM compression releases, emphasizing the need for proper compatibility checks. The S\u0026amp;S Cycle Easy Start camshaft offers a combination of ease of starting, high-performance, and durability for serious motorcycle enthusiasts looking to upgrade their Twin Cam engines from 1999 to 2006, excluding the 2006 Dyna models.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eFacilitates easy engine start by reducing initial crank compression\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCentrifugally retracts compression release lobe at higher RPMs for full compression operation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eOptimized for 95\" to 110\" engines with compression ratios between 10.5:1 and 11.5:1\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesigned for high RPM range of 3000 to 6000 rpm for peak performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMade in the USA with high-quality materials\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRequires high-lift springs and adjustable pushrods for installation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEnsure proper clearance checks: coil bind, valve-to-valve, and valve-to-piston\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eNot suitable for models with OEM compression releases\u003c\/li\u003e\u003c\/ul\u003e","brand":"S\u0026S CYCLE","offers":[{"title":"Default Title","offer_id":43032069374046,"sku":"09250747","price":906.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0012\/2545\/7758\/files\/12761.png?v=1784502139","url":"https:\/\/vtwinvisionary.com\/products\/s-s-cycle-easy-start-camshaft-106-4840-for-twin-cam-1999-2006-with-640-gear-drive","provider":"V-TwinVisionary","version":"1.0","type":"link"}
