I have a 96 200 has amazing low and midrange but wide open its not I raised the needle to the top clip not much help change the main from 145 to a 142 and put the clip 2nd from top still didnt improve it much if any the plug looks like its running rich. I cleaned the carb and filter looks like new has a new cylinder,piston,rings and a complete lower end rebuild by fredette has a stock pipe I havent checked the reeds wanted to get some ideas from the experts this my secound kdx and just came off of 2 different ktms and a cr250 so nabey I just expect more up top but I sure like the handling and comfort of this one just getting it setup the way I want it but thats half the fun ;)
