Once the engine reaches higher RPMs, the compression release lobe is centrifugally retracted, allowing the engine to operate normally with full compression and maintaining optimal performance. This camshaft is compatible with 95\", 96\", 103\", and 110\" engines featuring compression ratios between 10.5:1 and 11.5:1, ensuring broad applicability across various Harley-Davidson models. Its high-lift springs and adjustable pushrods are necessary for proper installation, providing precise valve control and performance tuning. The camshaft is built in the USA and is engineered for engines in the strongest 3000 to 6000 RPM range, delivering reliable power without sacrificing engine longevity. Proper installation requires the installer to verify coil bind, valve-to-valve clearance, and valve-to-piston clearance to ensure safety and performance. Not suitable for models equipped with OEM compression releases, this camshaft offers a significant upgrade for riders seeking improved startup performance and consistent power delivery. Its robust design and precise engineering make it a popular choice among motorcycle enthusiasts who demand quality and reliability from their engine components.\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 normal operation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatible with 95\", 96\", 103\", and 110\" engines with 10.5:1 to 11.5:1 compression ratios\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesigned for engines operating in the 3000 to 6000 RPM power range\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRequires high-lift springs and adjustable pushrods for proper installation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMade in the USA with durable construction\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRequires verification of coil bind, valve-to-valve, and valve-to-piston clearance during installation\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":43032070684766,"sku":"09250746","price":492.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0012\/2545\/7758\/files\/12760.png?v=1784502178","url":"https:\/\/vtwinvisionary.com\/products\/s-s-cycle-camshaft-easy-start-640-chain-drive-for-twin-cam-07-17-and-dyna-06-part-106-5235","provider":"V-TwinVisionary","version":"1.0","type":"link"}
