That #540 sizing sits at the absolute ceiling of the Mikuni hex main jet range where only the most aggressive big-bore builds and wild modifications can even put that much fuel to use. Getting your air-fuel ratio locked in at the correct jet size is crisp compared to chasing a stumbling throttle with guesswork. Having four jets on hand means you won't be caught short when you need to step sizes or swap back during a tuning session.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDelivers consistent fuel flow at the #540 jet size for repeatable tuning results.\u003c\/li\u003e\n  \u003cli\u003eBuilt to Mikuni hex main jet spec so flow rates match factory carburetor standards.\u003c\/li\u003e\n  \u003cli\u003eFits Mikuni hex-style carburetors for a direct no-fuss installation.\u003c\/li\u003e\n  \u003cli\u003eKeeps your carburetor fuel jetting powersports toolkit stocked with four jets per order.\u003c\/li\u003e\n  \u003cli\u003eDesigned for riders who won't accept a rich or lean condition when a jet swap fixes it.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eOrder the Mikuni Hex Main Jets #540 4-pack today from Dillon Powersports, authorized dealer.\u003c\/p\u003e","brand":"MIKUNI","offers":[{"title":"Default Title","offer_id":71127136305405,"sku":"134-8540","price":21.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0612\/9444\/4797\/files\/mikuni-hex-main-jets-4-pk-50-134-8050-0bd0c9f499_733670ae-e7cb-46f5-8161-7baec7ea41e8.jpg?v=1786548053","url":"https:\/\/shop.ddrv.com\/products\/mikuni-hex-main-jets-4-pk-540-134-8540","provider":"DDRV.com","version":"1.0","type":"link"}
