The Dynojet main jets and the Keihin round main jets are measured the same way. A DJ120 main jet is the very close to a Keihin 120 main jet. You can use the Keihin main jet of the same size in-place of a Dynojet main jet.

FMF developed these specs with a 32:1 fuel to oil mixing ratio of a 50/50 mix of race fuel and super unleaded, 0 - 1500 ft altitude at 70 degrees outside temperature.
Please note: There are way too many variables in jetting to give you a recommendation that works perfect. Use these specs for a reference to help aid you with your specific bike.

Yes, the 1998 Kawasaki KX80 has a Keihin PE26 carburetor. There is not a specific setting I could give you for jetting your bike. It would really depend on your location (altitude/temperature) and how your bike is running with the current jetting. Jetting can be very tricky, there isn't one setting that will work everywhere with every bike. I would recommend taking your bike to a local motorcycle dealership’s service department to have your bike properly jetted.
