Designed to cover VM18–VM44 family carbs and many TM, HS, HSR, RS, and flat-slide applications, the kit is intended as a flexible tuning resource rather than a guaranteed match for every model. Each jet is machined to consistent dimensions, letting hobbyists and pro mechanics experiment quickly without waiting for single, specialty parts.\u003c\/p\u003e\n\n\u003ch3\u003eWhich carburetors and motorcycles will this jet kit fit?\u003c\/h3\u003e\n\u003cp\u003eThe kit targets a broad range of Mikuni-style carburetors used on two- and four-stroke motorcycles, ATVs, and offroad machines. It includes sizes and profiles that match VM round and smoothbore, TM series, HSR, RS, and several flat-slide designs, plus many common replacement applications listed by OEM cross-reference numbers.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eVM series: VM18 through VM44 (round and smoothbore variants)\u003c\/li\u003e\n  \u003cli\u003eTM\/HS\/HSR\/RS\/flat-slide carbs: TM24–TM40, HSR42\/45\/48, RS34–RS40\u003c\/li\u003e\n  \u003cli\u003eCompatibility with many Suzuki, Kawasaki, Yamaha, Honda, Polaris carburetors using these platforms\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow are the jets organized and what sizes are included?\u003c\/h3\u003e\n\u003cp\u003eThe set groups large round mains, large hex mains, standard pilot jets, and VM-series pilot sizes so you have incremental changes for fine tuning.

This YUKIIATIF 42-piece kit is best for motorcycle and ATV owners, track mechanics, and backyard tuners who work on Mikuni-style carburetors and want a ready set of mains and pilots to experiment with fueling. It’s especially useful if you service multiple bikes or ride in varied climates and elevations and need immediate, incremental jet options without waiting for individual shipments. Note: confirm physical thread and dash size compatibility with your carburetor before installation; this kit supplies common sizes but may not replace specialized OEM jets exactly.\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: Will these jets fit my VM28 or VM32 carburetor?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes—this kit includes round and VM pilot sizes that cover VM28 and VM32 families, but check thread type and dash size for exact fit.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use this kit to tune for altitude changes?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Absolutely—multiple main and pilot sizes let you lean or richen the mixture to compensate for elevation and temperature shifts.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"YUKIIATIF","offers":[{"title":"Default Title","offer_id":67595295424697,"sku":"B0F2J5BV8V","price":54.6,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0822\/3765\/3177\/files\/yukiiatif-front-packaging-42pcs-jet-kit.jpg?v=1790586899","url":"https:\/\/redleafauto.ca\/products\/yukiiatif-carburetor-jet-kit-for-mikuni-tm-carburetors-42-piece-mains-and-pilots","provider":"Redleaf Auto","version":"1.0","type":"link"}
