KEIHIN Jet 130 — Manufacturer part number: 99101-124-1300
Main jet with a diameter of 130 from KEIHIN, designed for carburetion adjustments on compatible carburetors. An essential spare part for riders looking to fine-tune the air/fuel mixture and adjust the richness according to altitude, temperature, or mechanical modifications.
This jet is used during carburetor calibration operations: switching to a larger or smaller size to correct a mixture that is too lean or too rich. Before installation, check compatibility with your carburetor body and maintain a clean environment to avoid contamination of the fuel circuit.
Practical tips: carefully thread and tighten to avoid damaging the threads, clean the jet passage, and perform a gradual test under real conditions to validate the adjustment. If in doubt, have the installation checked by a workshop or carburetion specialist.
