This part being universal, it may require adaptations
Original MIKUNI main jet, reference N102221-0875. The MIKUNI MKD87.5 JET is a replacement part designed for Mikuni carburetors to precisely adjust the fuel flow. Numbered 87.5, it allows for calibration of the fuel mixture during maintenance or engine tuning operations.
Designed for riders who adjust their carburetor, this main jet directly impacts the air/fuel mixture: changing jet size is one of the key steps to correct a lean or rich engine, adapting the machine to a different filter, exhaust, or altitude.
A small but crucial part of the carburetor, this jet will suit both amateur mechanics and tuners. When replacing, be sure to make additional adjustments (needle, air/fuel screw, idle adjustment) to restore smooth operation. A wear and adjustment part, the MKD87.5 jet is the discreet tool to refine engine response and ensure controlled fuel mixture.
