Description
Keihin N424-26 slow/pilot jet for compatible Keihin carburetor applications. N424-26 is a brass pilot jet that meters fuel in the idle and low‑throttle range of the carburetor’s pilot circuit. This 23.5 mm long, M6 × 0.75 brass jet meters the pilot circuit at idle and small throttle openings.
N424-26 is used across compatible FCR, FCR-MX, PJ, PWM, PWK and PE carburetors, with selected CVK, BD and BH applications. It is shorter than the similar N424-21 series (28 mm), so always confirm the removed jet’s overall length and the required size before ordering

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.
