GY6 Cvk Main Jet

GY6 Carburetor Main Jet for Multiple Scooter Models

The GY6 CVK main jet controls how much fuel enters the air stream inside your carburetor, which directly shapes the mixture your engine burns. It is built to suit a variety of GY6 engines and can help your scooter run better. If you notice trouble starting or an unsteady idle, swapping the main jet may bring a clear improvement. Among the GY6 scooter parts available, this one matters most when re-jetting after you fit a new exhaust or air filter.

Purpose of This Part

The main jet adjusts the fuel-to-air balance in the carburetor, which can ease problems like bogging and surging. Replacing it is a good idea when performance drops off or after you change anything in the scooter's intake system.
