Unlike traditional rotation-dependent breathers, these pressure-differential reed valves open automatically when crankcase pressure exceeds cam chest pressure and close when pressures equalize — delivering on-demand airflow that keeps up with your engine at any RPM. Made in the USA, they install quickly with no timing mark alignment required.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePressure-differential operation — opens on demand, no crankshaft rotation dependency\u003c\/li\u003e\n\u003cli\u003eAutomatically compensates for lag during high-RPM operation\u003c\/li\u003e\n\u003cli\u003eReduces high-RPM oil carryover in engines with marginal piston ring seals\u003c\/li\u003e\n\u003cli\u003eNo timing mark alignment or rotating parts required for installation\u003c\/li\u003e\n\u003cli\u003eImproves airflow, reduces oil consumption, and supports smooth operation across the rev range\u003c\/li\u003e\n\u003cli\u003eMade in the USA by S\u0026amp;S Cycle\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 31-2096\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e 31-2096\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e S\u0026amp;S Cycle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.21 lbs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Manufacture:\u003c\/strong\u003e USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Harley-Davidson Evolution Big Twin, 1993–1999\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"S\u0026S CYCLE","offers":[{"title":"Default Title","offer_id":48383477842161,"sku":"31-2096","price":165.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0626\/1348\/7857\/files\/12593.png?v=1783437141","url":"https:\/\/howlingmoto.com\/products\/ss-cycle-31-2096-breather-reed-valves-evo-big-twin-93-99","provider":"Howling Moto","version":"1.0","type":"link"}
