Description
Proper jetting is the foundation of carburetor tuning—and running the wrong main jet costs you horsepower, fuel efficiency, and engine reliability. This 4-pack of Mikuni main jets gives you the flexibility to dial in the perfect air-fuel ratio for your specific riding conditions, altitude, and engine modifications. Whether you’re fine-tuning a stock setup or optimizing a heavily modified engine, having multiple jet sizes on hand eliminates guesswork and keeps you track-ready.
