Power-Up jet kit makes jetting your carb simple. FMF teamed up with Dynojet to produce a kit that offers a selection of jets and/or needles to get maximum horsepower out of ATV fitted with an FMF exhaust. Easy to use instructions have diagrams and step-by-step procedures to help you get your jetting where it needs to be, no matter the elevation. 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.
"Made the bike run very poorly. I followed the instructions and put in what they recommended... Bike ran very eradically. I changed the settings on the needle jet, the main jet size, the pilot screw turns... same eradic problems, the bike is unrideable.
I made all these changes one at a time, very methodically.
I went back to the stock jets, and the bike rips again!
