KEIHIN jet size 145, designed for carburetion adjustments on carburetors equipped with standard Keihin jets. This main jet allows you to adjust the air/fuel mixture richness during acceleration and at full throttle to optimize engine response according to the settings and operating conditions.
A simple and effective replacement part for those looking to work on carburetion: disassemble the carburetor, replace the existing jet with the desired size, then check the spark plug and settings. Before any intervention, check the reference and the general condition of the carburetor (cleaning of the passages and fuel filter is recommended). Using an appropriate jet is a key step to achieving a smooth throttle response and controlled consumption, while preventing misfires related to a mixture that is too lean or too rich.
Check compatibility with your model and keep reference 99101-393-1450 to ensure a proper exchange. No additional features provided — for precise adjustments, refer to the manufacturer's manual or a qualified workshop.
