MIKUNI MKU42.5 JET (Manufacturer's reference: VM28/486-42.5) — official replacement part for Mikuni carburetors. Designed for riders who maintain or optimize the carburation of their machine, this jet allows for precise adjustment of the fuel supply within the carburation circuit.
Ideal for tuning and maintenance operations, this jet is part of the carburation component family and fits into compatible carburetor bodies of the MKU series. Replacing a worn jet or adjusting the jet size is a common practice to achieve finer richness tuning during break-in, altitude changes, or after intake/exhaust modifications.
Before any intervention, check compatibility with your carburetor and consult the manufacturer's technical documentation. If you are unsure about the installation, seek assistance from a qualified workshop: improper tuning can affect combustion. Maintenance, precision, and safety — the fundamentals to keep your motorcycle ready for the miles ahead.
