The Nibbi PZ20 carburetor with 35mm air filter is for riders and mechanics restoring or upgrading 50cc–125cc 4-stroke Chinese-made ATVs, pit bikes, go-karts and scooters (examples: SSR, Taotao, Coolster, Apollo, Baja, Sunl and similar models). It’s suitable for owners who want a balance of improved throttle response, tuning flexibility, and reusable filtration without moving to a much larger carburetor. Always measure the intake and bolt pattern before purchase and use the included jets to tune for local conditions.\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: Is the Nibbi PZ20 compatible with my 110cc ATV?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: If your engine intake is 20mm and bolt spacing is 47mm center-to-center, the PZ20 is compatible with most 110cc Chinese 4-stroke ATVs.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do I need extra jets to tune for altitude?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
