KEIHIN Jet 180 — manufacturer reference 99101-393-1800. An essential part for riders looking to fine-tune the carburation of their motorcycle, this Keihin jet meets the precise air/fuel mixture adjustment needs on carburetors equipped with interchangeable jets.
The jet plays a key role in achieving consistent carburation at all RPMs: starting, low RPM, acceleration, and full throttle. Replacing or adjusting the jet allows for refining the throttle response and avoiding overly lean or rich engine operation. Designed with Keihin's expertise, it fits into classic jet sets for precision adjustments.
Practical advice for the motorcyclist: check compatibility with your carburation and keep the manufacturer reference when ordering. For optimal and safe tuning, conduct gradual tests (idle, revving, riding) and, if necessary, have the configuration validated by a specialized workshop.
