MIKUNI MKD40 JET — Brand: MIKUNI · Manufacturer part number: N102221-040
An essential carburetion part for motorcyclists and tuners, the Mikuni MKD40 jet allows for fine-tuning the fuel dosage in the fuel circuit. Designed to integrate with compatible Mikuni carburetors, it directly affects the richness and engine behavior during acceleration and revving. Lightweight and discreet, this jet is the adjustment element used to achieve a carburetion suited to the operating conditions (altitude, temperature, intake or exhaust modifications).
Usage tips: proceed in increments when changing jets and monitor the color of the spark plugs to assess the richness. If you are unsure about compatibility or the size to adopt, consult a motorcycle mechanic or refer to your carburetor documentation. The MKD40 jet is a precision adjustment component — a small adjustment can significantly alter the fuel mapping.
