Hi there, I was surprised when I pulled my plug and its still burning hot. I was hoping for some coloration. The stock jets were pulled after the desmog and I have a 175 main, red needle with clip on 5th position and a 42 pilot jet. I am running some 75mph runs with a trail speed of 40mph in the sand. I am in Orlando FL. I got one of those adjustable fuel screws, warmed the bike up and then turned it in all the way. I was surprised that it didnt cut off with it in all the way but ran rough. It smoothed out when i turned it a quarter of the way out. So down low it almost says the 42 is too big but that cant be. Up top I think its lean. What are your suggestions??? bike has about 15 hours on it. Its an 08 530.
