ah, of COURSE they are black. You pulled your O2 sensors so the system simply pours in excess fuel. No mystery here, right?
No, my plugs are black with the O2 sensors plugged in, the thrush mufflers installed, and the air strip removed. When I did unplug the O2 sensors it didnt seem to run any different, but I didn't run it that long, just long enough to get annoyed by all the popping, like I said it popped between every shift and on decel. I plugged the O2 sensors back in, the popping is pretty much gone, I get one once in a while now, but seems to be when the bike is cold, and the temps here have been cold.
