KEIHIN Main Jet 172 — Manufacturer Ref: 99101-357-1720
Calibrated main jet 172 by KEIHIN, designed for riders looking to fine-tune their carburation. A simple yet essential part of the carburetor, the main jet regulates the amount of fuel admitted into the main circuit and directly affects the richness of the mixture at mid-to-full throttle openings. Ideal for tuning, replacement, or optimization during engine preparation.
Installation: disassembly of the carburetor is required to access the jet. Check compatibility with your carburetor model or machine before installation. For optimal tuning, proceed in steps while monitoring the spark plug and engine behavior at different throttle openings. If in doubt, consult a workshop or a carburetion specialist.
