MIKUNI Needle Jet 990-793-003-P-0

Carburetor tuning at part-throttle conditions requires precision—and that's where needle jets make their impact. The MIKUNI 990-793-003-P-0 is a genuine Mikuni component engineered to give you direct control over fuel atomization in the 1/4 to 3/4 throttle range, the zone where most street and track driving happens. If your carb feels lean, rich, or simply unresponsive in mid-range, swapping needle jets is one of the most effective tuning adjustments available.

This needle jet features the authentic Mikuni engineering you expect—made in Japan with precise internal diameter specifications that directly influence fuel delivery characteristics. The size coding system (alphabetically and numerically stamped) ensures you select the exact taper profile your engine needs.
