KEIHIN Main Jet 92 (manufacturer part number 99101-357-0920) — original jet designed for KEIHIN carburetors. Designed to control the fuel flow in the main engine speed range, this jet allows for fine-tuning of the carburation in conjunction with needle and mixture screw adjustments.
Ideal for riders who perform fine adjustments to their carburation, this main jet size 92 adjusts the amount of fuel delivered to the engine in the high-speed range. Changing the jet is a standard step during re-jetting following modifications (exhaust, air filter, altitude) or to restore clean engine behavior across the entire acceleration curve.
Simple installation for a skilled DIYer: drain the carburetor, remove the float to access the jet, replace and tighten according to the manufacturer's torque specifications. For precise tuning and optimal safety, prefer a bench check or the intervention of an experienced motorcycle tuner.
