Description
Keihin N424-14 main air jet, used in Keihin CR-series smoothbore carburetors to regulate airflow through the main air circuit, working alongside the main fuel jet to fine-tune the air/fuel mixture at higher throttle openings.
Unlike a main fuel jet, this component controls air rather than fuel delivery, so selecting the correct size affects mid-to-high RPM mixture and throttle response rather than fuel flow directly.
Specifications:
-
Overall Length: 22.0 mm
-
Body Diameter: 5.5 mm
-
Thread Diameter: 4.9 mm
Notice
Before You Order — Measure Your Jet First
Remove the jet from your carb and physically measure it. If it does not dimensionally match this listing, this is not the correct jet — do not buy it.
Buyer is solely responsible for confirming the correct jet size before purchasing. Do not rely on year/make/model fitment guides — they cannot be guaranteed 100% accurate.
All jet sales are final. No returns or exchanges — no exceptions.
