What size jet you need to upgrade to will depend on the local elevation and the season (outside temperature) that you will be riding in.  We provide a size 128 main jet.\u003cbr\u003e\u003cbr\u003e\u003cem\u003e***This dual-layer UNI air filter MUST be oiled with foam filter oil and cleaned regularly. A properly oiled filter prevents dust particles and debris from getting into the carburetor and your engine. This is essential for proper operation and engine longevity. You WILL eventually destroy your engine if this filter is not oiled with the proper product. This kit will mount as-is to most 125cc and 150cc GY6-based engines***\u003c\/em\u003e\u003c\/p\u003e","brand":"HammerHead Performance","offers":[{"title":"Default Title","offer_id":53483511677293,"sku":"intakekit_hhp","price":59.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1004\/2710\/4621\/files\/airintakekit_2__1.jpg?v=1782374212","url":"https:\/\/hammerheadperformance.com\/products\/gy6-air-flow-performance-upgrade-for-150cc","provider":"HammerHead Performance","version":"1.0","type":"link"}
