Carbureted four strokes need this upgrade. Adjust lean rich mixture by hand while it's running. Pipe red hot? Richen it up by turning this screw out a half turn at a time. Sooty exhaust? Lean it out by turning screw in a bit.Read All Reviews

I replaced an old R and D that got wore out. These are awesome. They work great and you pretty much will not have an issue again.Read All Reviews

Although not a Keihin factory jet it is of good quality. The jet size is stamped onto the bottom (as it sits in the carb) and it pretty small for this old man to read!! I installed and it fits fine and seems to be milled to the correct size.Read All Reviews
