{"product_id":"mcs970602","title":"S\u0026S Steel Breather Valve. Std – 1936–1947 Big Twin","description":"\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eHigh quality steel breather valve for use as stock or high performance replacement. Note: S\u0026amp;S breather valves come with elongated breather holes to increase the duration of the vacuum; allowing more oil to be drawn from the cylinder heads. This has no disadvantage in any model year; either stock or Big Inch motor. Note: that steel breathers require steel breather valve spacers. Plastic breathers require plastic spacers. Do not intermix steel and plastic parts. Note: A .030\"oversize breather is available to save worn or damaged crankcases as 970603. A JIMS breather hole reamer (MCS 978343) will ream the damaged hole to +.030\" so a +.030\" breather can be used.\u003c\/p\u003e\n\u003ch2\u003eFitment\u003c\/h2\u003e\n\u003cp\u003e36-47 Big Twin (NU)\u003c\/p\u003e\n\u003ch2\u003eProduct Details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e S\u0026amp;S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e MOTOR PARTS \u0026gt; BREATHER VALVES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct code:\u003c\/strong\u003e 970602\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePart Numbers\u003c\/h2\u003e\n\u003cp\u003eMCS Part Number: 970602\u003cbr\u003eManufacturer Part Number: 106-5070\u003cbr\u003eOEM Number: 25300-36\u003c\/p\u003e","brand":"S\u0026S Cycle","offers":[{"title":"Default Title","offer_id":44334665498944,"sku":"MCS970602","price":152.73,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1329\/4265\/files\/970602ak.jpg?v=1785953018","url":"https:\/\/hogparts.co.uk\/products\/mcs970602","provider":"Hogparts UK Ltd","version":"1.0","type":"link"}
