KEIHIN Main Jet 185 — Manufacturer Ref: N424-27185
A replacement part dedicated to fuel mixture, the KEIHIN Main Jet 185 allows for adjustments to the air-fuel mixture during carburetor tuning. Known among mechanics and DIY motorcyclists, this jet is used to calibrate the amount of fuel delivered at mid and high RPM, in order to adjust engine behavior according to altitude, temperature, or modifications made to the setup.
Convenient to store in your workshop toolbox, this jet is part of the maintenance routine when working on a Keihin carburetor: disassembling the carb, replacing the main jet, and then checking the fuel mixture. It is aimed at those who enjoy finely tuning their mixture and optimizing throttle response without resorting to complex modifications.
Don't forget: choosing a jet should be accompanied by testing and checking the spark plug color to achieve a suitable and safe mixture adjustment.
