Description
Fine-tuning your carburetor's fuel delivery is critical for optimal performance, throttle response, and engine reliability—and the main jet is where that precision starts. Whether you're dialing in a fresh build, compensating for altitude changes, or optimizing fuel mapping on a modified engine, a properly sized main jet ensures your air-fuel ratio stays in the sweet spot under load. This 4-pack of MIKUNI #660 main jets gives you the flexibility to experiment with jetting without downtime between sessions.
