Description
The N424-74C is the long K27 / 27-xxx pilot jet used in Keihin PD-series carburetors. It meters fuel at idle and small throttle openings. Overall length is 28.0 mm, with a 5.0 mm maximum head diameter and a 4.9 mm thread diameter.
Choose the required size from 035 to 075. Match the series and dimensions to the removed jet, particularly when comparing it with the similar N424-21. This is not a universal replacement for other Keihin pilot jet series.
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.
