The correct carburetor setting is a crucial point if you want to exploit the full potential of your engine. As with internal rotor ignition, racing CVT or clutch, a larger carburetor also requires precise tuning. With a Keihin jet set and the right size, this can be done quickly.
After a short test ride at full throttle, a glance at the spark plug is enough: black = too rich, this means try a smaller jet; white = too lean, try a larger jet. The needle and pilot jets can then be fine-tuned depending on the engine behavior at low and mediumRPM. The size specifications are of course engraved on each jet.
Careful adjustment not only ensures more power, but also increased reliability. The range includes main and pilot jets (also known as idle jets) to make carburetor tuning easier and to exploit the full potential. A well-tuned 21mm carburetor will perform better than a 28mm carburetor with the wrong jetting. For models with a Powerjet system, the matching replacement parts are also available. Just browse the category, filter as needed – the right jet is easy to find.
