KEIHIN MAIN JET 65 — Manufacturer reference: 99101-357-0650
Main jet by KEIHIN, size 65. Designed for the main circuit of the carburetor, this jet allows for the adjustment of fuel flow and the richness of the air/fuel mixture. A simple yet essential part of the carburetor, it plays a direct role in throttle response and combustion consistency.
Ideal for riders who are tuning their carburetion, this jet is used during a richness adjustment to correct a mixture that is too lean or too rich depending on altitude, temperature, or engine modifications. Easy installation and removal with an appropriate screwdriver; remember to work on a clean carburetor and check the sealing of the jet well.
Before purchasing, confirm compatibility with your KEIHIN carburetor or the technical documentation of your machine. Proper carburetion remains a balance between reliability, consumption, and engine behavior — this jet is part of the basic adjustments to master this balance.
