Description

Keihin 99101-357 hex-head main jets meter fuel through the carburetor's main circuit. The family is documented across several Keihin carburetor applications, including PWK.

Jet size is the variant axis. Each whole-number member uses a 99101-357-XXX MPN whose suffix identifies its size, so select the size specified for the carburetor and engine setup rather than relying on family fitment alone.

The standard non-Air-Striker PWK33/S46 configuration uses the #165 member, MPN 99101-357-165, at reference 26. This is configured PWK33 jetting, not a universal size for every PWK model or setup.

  • Family MPN: 99101-357
  • Head: 6.0 mm hex
  • Dimensions: 16.5 mm long, M5 x 0.8 thread
  • Standard PWK33/S46: #165 at reference 26

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.
