[QUOTE="Trfsrfr, post: 222444, member: 3959"] I forget when I last ran this bike before I got it replated, but I looked at the settings from ProCircuit that you gave me [USER=408]@Mihylo33[/USER], and my MJ is a 172s, but it ran good til about mid-throttle then started getting that boogery sound as I like to call it. But my plug (an Iridium br9exi) is black and sooty. I was thinking it was rich cuz of that boogery sound, but now I'm 2nd guessing myself with that 172 MJ. I'm guessing my float is off. Took the slide out but cant get the needle out cuz I dont have a socket that fits. Not sure why cuz I'm pretty sure I've had it out before. What size is that thing? [/QUOTE]
