Tuning your carburetor? This 33-piece jet kit has everything you need! You get 22 main jets ranging from #100 to #182 and 11 slow pilot jets from #32 to #58 - all made from anti-rust brass that stands up to fuel and time. The jets are compatible with PWK, CVK, and PE type carburetors from brands like Keihin, Mikuni, OKO, KOSO, and more. Perfect for tuning scooters, ATVs, karts, and motorcycles with 125cc to 250cc GY6 motors. Each jet comes individually packaged and clearly marked, so no guessing about sizes during your tuning sessions. Having this range of sizes lets you dial in your air/fuel mixture perfectly for your specific setup and elevation. The brass construction ensures consistent flow and durability. Whether you're dealing with bogging, hesitation, or just want to optimize performance after modifications, having the right jets makes all the difference. Much better than buying jets individually and waiting for shipping each time you need a different size. Important note - these won't work with CV, VE, or larger CVK carburetors above 3cm, so check your carb type before ordering. If you're serious about carb tuning, this comprehensive jet kit is an absolute must-have for your toolbox!
