Main jet Mikuni MKN1.2, spare part intended for carburetion adjustments. Designed to replace or refine the calibration of the jet on carburetors, this jet allows for the adjustment of fuel flow in the main passage of the fuel circuit. A simple yet essential part for achieving the right air/fuel mixture for your machine after modifications or changes in altitude and temperature.
Usage: replacement on carburetors to adjust the richness.
Advantage: facilitates more precise engine tuning at mid and high RPM.
Installation: fits in place of the existing jet — a straightforward task for a DIY motorcycle enthusiast familiar with carburetion.
Compatibility: Mikuni type jet — check reference and dimensions on your carburetor before ordering.
Ideal for riders who maintain their own carburetor or who seek to adjust the carburetion after installing accessories (exhaust, air filter). Keep the original jet for the possibility of returning to the initial setting and systematically check the mixture screw and synchronization of the bodies before road testing.
