This BH-Motor set includes two full rebuild kits tailored to Mikuni-style carburetors used across many Sea-Doo SP\/GTX\/GTS models, numerous Yamaha WaveRunner and Wave Blaster variants, and select Polaris SL and TS series. Each kit replaces the small components that fail first: gaskets, O-rings, needles, and diaphragms, restoring proper fuel metering and sealing.\u003c\/p\u003e\n\n\u003ch3\u003eWhat parts are included and why do they matter?\u003c\/h3\u003e\n\u003cp\u003eEach kit supplies the service items technicians typically replace during a carb overhaul so your jets, bowls, and floats can work as intended.

These BH-Motor twin carburetor rebuild kits are aimed at PWC owners, boat builders, small-engine mechanics, and DIYers who want a cost-effective way to restore fuel delivery on Mikuni-equipped watercraft. If you maintain Sea-Doo, Yamaha, or Polaris models from the 1990s through the early 2000s and need to stop leaks, cure poor idling, or regain crisp throttle response, these kits provide the common replacement components technicians expect for a reliable rebuild.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do these kits include everything needed for two carburetors?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — each order contains two complete Mikuni-style rebuild kits covering the common rubber and metering parts for both carbs.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use this kit on non-Mikuni carbs?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: These kits are made for Mikuni-style twin carbs; non-Mikuni carbs may require different parts or a model-specific kit.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"BH-Motor","offers":[{"title":"Default Title","offer_id":48084840710302,"sku":"B076DNSZ34","price":34.98,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/bh-motor-front-packaging-twin-carb-rebuild-kit.jpg?v=1785863282","url":"https:\/\/northtrailauto.ca\/products\/bh-motor-mikuni-twin-carb-rebuild-kits-2-sets-for-sea-doo-yamaha-polaris-gaskets-diaphragms","provider":"North Trail Auto","version":"1.0","type":"link"}
