It helps the engine run smoothly when the throttle is barely open. If your scooter stumbles when you accelerate or has trouble staying running at idle, this jet could be the cause. You can find it among \u003ca href=\"\/collections\/scooter-carburetors\"\u003escooter carburetors \u0026amp; jets\u003c\/a\u003e, where it helps restore the correct fuel mixture for your engine.\u003c\/p\u003e\u003ch3\u003ePerformance Improvement\u003c\/h3\u003e\u003cp\u003eThis idle jet controls the fuel mixture from 0% to roughly 25% throttle, so it has a direct effect on how the scooter behaves at low RPM. A blocked or wrongly sized jet often causes rough idling and a throttle that feels slow to respond. Made from high-grade brass with precise calibration, it supports steady fuel flow and more stable tuning.\u003c\/p\u003e\u003ch3\u003eWhen to Replace Your Idle Jet\u003c\/h3\u003e\u003cp\u003eAfter fitting a high-performance exhaust or a larger cylinder, you might need a bigger jet to prevent a lean running condition. The usual step is up one size, for example from a #38 to a #40. It's worth inspecting the idle jet for blockages whenever you notice poor low-speed performance.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Keihin PB \/ CVK Idle Jet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Machined Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAvailable Sizes:\u003c\/strong\u003e #38, #40, #42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Scooter Co 50cc 2-stroke models and Chinese GY6 50cc scooters with Keihin PB or CVK-style carburetors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBuddy 50 (50cc 2-stroke)\u003c\/li\u003e\n\u003cli\u003eRoughHouse 50 (50cc 2-stroke)\u003c\/li\u003e\n\u003cli\u003eRattler 50 (50cc 2-stroke)\u003c\/li\u003e\n\u003cli\u003eBlack Cat 50 (50cc 2-stroke)\u003c\/li\u003e\n\u003cli\u003eTaoTao, Wolf, Ice Bear and Bintelli GY6 50cc scooters (139QMB, PD18J or CVK-style carburetor)\u003c\/li\u003e\n\u003cli\u003eKeihin PB series carburetors\u003c\/li\u003e\n\u003cli\u003eMost 18mm-20mm CVK clone carburetors\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eHow to choose:\u003c\/strong\u003e Pick the jet size based on your scooter's engine setup, selecting #38, #40 or #42 as required.
