Each carburetor is pre-jetted with a proven baseline setup to provide an excellent starting point. Every engine combination is different, so final jetting may be required depending on your engine modifications, fuel type, elevation, temperature, and riding conditions. If you need help with tuning, send me a message. I can recommend a jetting setup that will get you close and can also supply additional jets for fine tuning.
