About this Jitsie Needle Jet PWK 28MM Carburettor

  • replacement needle jet for Keihin PWK 28 mm carburettors
  • regulates fuel flow between the main jet and the needle
  • essential for smooth throttle response and precise fuelling
  • tapered design fits only one way — press firmly until it clips into place
  • high-quality brass construction for durability and accurate metering
  • small and easy to lose — always good to have a spare

The Jitsie needle jet for Keihin PWK 28mm carburettors plays a key role in controlling fuel flow from the main jet to the jet needle. Working together with the needle, it determines the fuel mixture from roughly ¼ to ¾ throttle, making it essential for smooth, consistent power delivery.

This small part is easy to lose during carburettor servicing or cleaning, so keeping a spare on hand is always a good idea. When installing, make sure the tapered side faces upward – the jet only fits in one direction. Push it firmly into place until it clicks securely into position inside the carburettor body
