Description
Air, rather than fuel, passes through the Keihin N424-14 main air jet. Used in CR-series smoothbore carburetors, it works with the main fuel jet to adjust the mixture at higher throttle openings.
The N424-14 measures 22.0 mm long, with a 5.5 mm body diameter and a 4.9 mm thread diameter. Select the jet size specified for your carburetor setup; this main-air jet is separate from the main fuel and pilot jets.
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.
