This part being universal, it may require adaptations
KEIHIN Jet 162 — original part by KEIHIN for precision tuning enthusiasts. Designed to replace the existing jet in your carburetor, this jet reference 99101-393-1620 carries the designation "162" and is aimed at riders looking to fine-tune the air-fuel mixture and engine behavior during acceleration.
Simple and robust, this jet installs into the corresponding opening of the carburetor and is part of the essential adjustments during a richness rejet, filter change, or after an intake/exhaust modification. It allows for adjusting the fuel-to-air distribution in the relevant range and is therefore an integral part of mixture management.
Before installation, check compatibility with your carburetor model and your initial settings. The operation requires careful disassembly of the carburetor and appropriate tools — a small screwdriver or jet wrench — and should be performed on a cold engine or by a professional if you are unsure. A correct adjustment contributes to a more consistent engine response and controlled fuel consumption.
