Our new Power-Up jet kit makes jetting your carb simple. We’ve teamed up with Dynojet to produce a kit that offers you a selection of jets and/or needles to get maximum horsepower out of your motorcycle or ATV fitted with an FMF exhaust. The easy to use instructions have diagrams and step-by-step procedures to help you get your jetting where it needs to be, no matter what elevation you ride at. No more driving back and forth to the dealer with a handful of jets and needles with a million questions running around in your head on where to start.
