Description

Keihin N424-21 pilot and slow jets meter fuel through the carburetor's idle and low-throttle circuit. This listing covers the N424-21 family in 19 size options from 035 to 080.

Jet size is the variant axis: each option identifies a size-specific member of the N424-21 family. Select the series and size specified for the carburetor or match the removed jet rather than choosing by carburetor family alone.

The standard non-Air-Striker PWK33 configuration uses the #52 member, MPN N424-21-52, at reference 10. That configured size applies to this PWK33 setup and is not universal across PWK models or configurations.

  • Family MPN: N424-21
  • Size range: 035–080
  • Dimensions: 28 mm long, 5.9 mm thread diameter
  • Standard PWK33: #52 at reference 10

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.
