Well i finally got around to it. I installed my uni, powertech 4 and dynojet kit this weekend. I am very pleased with the results. I live in a suburb so i really couldnt open it up past 45, dont want to piss off the neighbors. But it pulls really good, actually really good. I am running the 148 main jet with 3 turns out, just like the directions said. It has a little back fire when i goose the gas on and off. Im going to ride it next weekend to see how the plug looks. What a great combo. I am also goign to take the slack out of the cable.
