If the slide physically moves but the carb doesn't respond smoothly, inspect the membrane.\u003c\/p\u003e\n\u003ch3\u003eIs this the OEM Harley part?\u003c\/h3\u003e\n\u003cp\u003eThis is the aftermarket equivalent. The OEM Harley part is only sold as part of a complete slide assembly, making this a cost-effective standalone option.\u003c\/p\u003e","brand":"Harddrive","offers":[{"title":"Default Title","offer_id":53035423760495,"sku":"820-50920","price":9.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/6734\/6543\/files\/output_f64c7ead-4a98-4c5f-ae7f-ac1b9930bbb2.png?v=1779561529","url":"https:\/\/vtwinbikers.com\/products\/harddrive-throttle-slide-vacuum-membrane-keihin-hd-cv-carb-820-50920","provider":"Vtwinbikers","version":"1.0","type":"link"}
