The reeds flex on every closed throttle and eventually one cracks.\u003c\/p\u003e\n\u003ch2\u003eBoth Ends Need Closing\u003c\/h2\u003e\n\u003cp\u003eRemoving the housing leaves an opening where the hose attached, and unfiltered air entering an intake is a worse outcome than the system ever was.\u003c\/p\u003e\n\u003ch2\u003eA Repair Wearing Another Name\u003c\/h2\u003e\n\u003cp\u003eOn any Ducati past its first decade the reed housing has limited working life left. Fitting aluminium removes a job that was coming rather than merely deleting an emissions device, which is why the argument is strongest on older machines and weakest on new ones.\u003c\/p\u003e\n\u003ch2\u003eWhy the Cover Does Not Need a Gasket\u003c\/h2\u003e\n\u003cp\u003eThe head face is machined and flat, so a rubber ring in a turned groove seals against it with the fastener load doing nothing more than holding the two together. A paper gasket in the same place would bond, tear on removal and leave the owner scraping a cylinder head for an hour.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDucati SuperSport 939 S (2017–2020)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003eJP ES 041\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eManufacturer\u003c\/th\u003e\n\u003ctd\u003eJetPrime\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eCNC-milled Ergal 7075\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFits\u003c\/th\u003e\n\u003ctd\u003eDucati SuperSport 939 S (2017–2020)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInstallation\u003c\/th\u003e\n\u003ctd\u003ePlug-and-play, no wiring harness modifications required\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"JetPrime","offers":[{"title":"Default Title","offer_id":53636287693066,"sku":"JP ES 041","price":236.0,"currency_code":"ILS","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/002_00_44059939-965e-448b-bca6-b7bd695832f2.png?v=1788711527","url":"https:\/\/inter-pace.com\/en-il\/products\/jetprime-pair-system-eliminator-cover-ducati-supersport-939-s-2017-jp-es-041","provider":"Inter-Pace","version":"1.0","type":"link"}
