KEIHIN Main Jet 120 — Manufacturer reference: 99101-357-1200
Replacement main jet designed for KEIHIN carburetors. Numbered 120, this jet allows you to adjust the amount of fuel delivered at full throttle and in the high RPM ranges. Essential for carburetion adjustments, seasonal tuning, or restoring a carburetor after disassembly.
Easy to replace, this jet installs on the carburetor body after draining the well and removing the existing jet. For optimal adjustment, be sure to check all carburetion components (idle jet, needle, float height) and follow the motorcycle manufacturer's recommendations. Using an appropriate jet is a key step to achieving clean carburetion and smooth engine response.
Check compatibility with your carburetor before purchase and keep the manufacturer reference for any future interventions or additional parts orders.
