Description

Fine-tuning your carburetor's fuel delivery is essential for consistent performance, whether you're dialing in a race engine or optimizing a street build. A worn or incorrect main jet directly impacts throttle response, fuel economy, and peak horsepower—making proper jetting non-negotiable. This 4-pack of MIKUNI #720 main jets gives you the right sizing for Mikuni's most popular platforms, with the precision engineering you expect from Japanese OEM-quality components.

Each jet is manufactured to exact specifications, ensuring reliable metering across your carb's operating range. Stock up on spares and have the exact sizing you need for multiple tuning sessions or as backups for race season.
