42 Pcs Carburetor Jet Kit for Mikuni. Main and Pilot Slow Jet N100.604. Brass construction with precise drilled orifices. Fits VM18-VM44 TM24-TM38 HSR42/45/48 RS34-RS40 carburetors. Compatible with Honda Suzuki Kawasaki Yamaha.

• 【42 JETS IN 4 CATEGORIES COVER YOUR TUNING RANGE】The kit includes 19 large round main jets (sizes 90 through 190 in increments of 5-10), 10 large hex main jets (130 through 280 in increments of 20), 7 TM pilot jets (17.5 through 40), and 6 VM pilot jets (25 through 60) — this spread covers lean-to-rich tuning from sea level to 8,000 feet elevation without ordering.
• 【REPLACES N100.604 VM28/486 VM4/042 VM22/210 AND MORE】Each jet follows the N100.604 thread standard and cross-replaces VM-series part numbers including VM28/486, VM4/042, and VM22/210 — drop these into any Mikuni VM18 through VM44 round-slide carburetor, TM24 through TM38 flat-slide, HSR42/45/48, or RS34 through RS40 rack carburetor without modifying threads or drilling jet bodies, because the thread pitch and seat angle match OEM Mikuni specifications measured with a digital caliper at 6mm × 0.75mm pitch.
• 【BRASS CONSTRUCTION WITH PRECISE DRILLED ORIFICES】Each jet is machined from solid brass with a through-hole drilled to ±0.01mm tolerance — the orifice diameter determines fuel flow, and a ±0.01mm variance on a 1.0mm main jet translates to less than 2% flow deviation compared to cheap zinc-alloy jets that can be off by 0.05mm or more, causing a lean condition on cylinder one and a rich condition on cylinder two that no amount of mixture screw adjustment will fix.
• 【FOR MOTORCYCLE ATV DIRT BIKE AND UTV TUNERS】Whether you are re-jetting a VM34 carburetor on a vintage Suzuki dual-sport after installing a less-restrictive exhaust, tuning TM36 flat-slides on a Honda track bike for a different track altitude, or dialing in the pilot circuit on a Yamaha ATV that fouls spark plugs at idle, the 42-piece range gives you the exact size you need in one kit — works on 2-stroke and 4-stroke applications across Honda, Suzuki, Kawasaki, Yamaha, and Polaris platforms.
