Keihin PWK 28 Needle Jet

The small brass tube that sticks out in to the main bore of the carb, the needle moves in and out of this jet making it bigger or smaller, as a coincidence of this it can wear out requiring replacement. If the bike is running rich around 1/8 to 1/4 throttle, I'd recommend replacing this and the needle at the same time before trying different needles or jetting.
