{"product_id":"s-s-reed-breather-valve-std-o-d","title":"S\u0026S, reed breather valve. STD O.D.","description":"For head vented models. Similar in function to the S\u0026amp;S Reed valve for Twin Cam models. Unlike the regular rotating breather valve which is opened and closed by crankshaft rotation and pre-set timing; the Reed valve uses actual pressure to open and close on the right moment; at different RPM''s this ideal moment varies. This means an advantage for the Reed valve over the regular mechanical timed breather valve in reducing oil carry over; especially in high RPM conditions.   Note: Not suitable for use with crankcase vented models.\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e 93-99 Evo Big Twin (NU)\u003c\/p\u003e","brand":"S\u0026S","offers":[{"title":"Default Title","offer_id":54307665871175,"sku":"970608","price":212.75,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0987\/7812\/0519\/files\/970608k.jpg?v=1784469780","url":"https:\/\/www.chopperessentials.com\/products\/s-s-reed-breather-valve-std-o-d","provider":"Chopper Essentials Co.","version":"1.0","type":"link"}
