I am having some problems with my jetting I have ESR 310 kit w/ full drag port, 38 A/S & a FTZ drag pipe. My bike rips but when I hit 3/4 to full throttle it breaks up I am currently running a 48 pilot clip on 3rd from top and a 185main my plug looks like a medium brown but the end of my pipe is white. I had a 182 main in it and put the 185 in it but still doin it. I am running c-16 mixed @ 40:1 with maxima 927. I dont know if it is leaning out on top or if it is too fat?? What would cause the breaking up on top?? I am @ 700ft above sea level. Thanks

 

I got it figured out, 180 main, 50 pilot, DGH needle on 4th clip from top, 2.5 turns out on air screw, It rips now!
