MIKUNI MKD90 JET — Manufacturer reference: N102221-090
Replace or adjust the heart of your fuel system with this Mikuni MKD90 jet, a part designed for riders who are concerned about precise air/fuel mixture tuning. Designed for Mikuni carburetors, this jet allows for the fine calibration essential during maintenance, adjustments after intake or exhaust modifications, or simply to regain consistent throttle response.
The jet directly affects the richness of the carburetor and influences throttle response, idle, and the consistency of the mixture. Its manufacturing and calibration must be precise to ensure stable tuning: this is why using an original Mikuni jet guarantees compatibility and calibration that meets the brand's standards.
Workshop advice: check the compatibility with your carburetor model and your tuning needs before installation. If in doubt, have the choice and installation checked by a professional or a carburetion specialist to avoid any engine imbalance.
