KEIHIN Jet 172 — the compact replacement part for those who want to master carburetion. Designed to fit into carburetors that accept standard jets, this jet number 172 allows you to adjust the air/fuel mixture to restore or fine-tune engine settings.
Whether you are an amateur mechanic or a tuner, this jet is a simple yet essential component for working on the mixture richness. Ideal during a needle change, an intake modification, or to correct a mixture that is too lean/rich, it installs directly into the designated opening of the carb body. Be sure to compare the size with the old jet before installation and conduct road tests or bench tests in safe conditions.
Practical tips: keep the old jet for comparison, clean thoroughly before installation, and make gradual adjustments. If in doubt, entrust the installation to a workshop or motorcycle tuner.
