This part being universal, it may require adaptations
The MIKUNI MKF42.5 jet (manufacturer reference N100606-0425) is a spare part designed for Mikuni carburetors. Designed for tuning operations, it allows for the adjustment of the amount of fuel sent to the bowl in order to refine the air/fuel mixture richness during the setup.
This 42.5 size jet is suitable for common carburetion interventions: changing the main jet to vary the richness, tuning tests on a bench or on the road, and preventive maintenance after cleaning the carburetor. Installing or replacing a jet requires a clean disassembly of the carburetor, checking the orifices, and, if necessary, using precise tools to avoid damaging the head.
Practical advice: check compatibility with your type of Mikuni carburetor before installation, carefully clean the circuits, and carry out gradual tests to validate the adjustment. Suitable for skilled DIYers and workshops looking to achieve reliable calibration during mixture adjustments.
