KEIHIN Main Jet 148 — Manufacturer reference: 99101-357-1480
Original KEIHIN main jet, size 148, designed for fine-tuning the fuel mixture on KEIHIN carburetors. A replacement or adjustment part for riders and mechanics looking to refine the richness at mid and full throttle. The jet directly affects the fuel supply when the throttle is opened further, allowing for adjustment of the mixture according to altitude, temperature, or intake/exhaust modifications.
Easy to install for a skilled DIYer or workshop, this jet fits into the jet holder of compatible carburetors. Ideal for carburetor tuning sessions (synchronization, needle adjustment, idle adjustment) when it is necessary to adjust the richness. Does not modify other components and should be chosen based on adjustment needs and carburetor specifications.
Product delivered as is: check compatibility with your KEIHIN carburetor before installation. If in doubt, have the installation and adjustments performed by a professional.
