Just put on mikuni 28 mm flat slide carbs. Started up fist kick and idles like it's at half throttle, I checked the cable and the slide in the carb it looks perfect, I have stock motor, toomey t6 pipes, force reeds and uni foam filters. 2005 banshee. I turned the idle screws on the side of the carbs all the way in and backed them out 1/2 turn. I have 300 main jets in and it's 30 degrees out in Detroit Michigan, if I take the filters off and hold my had a 1/4 inch or so in back of the carbs it idles perfect like restricting air, before I take the carbs apart any ideas,
