Yeah, the Rat forum is where I found my other info. I haven't done the EFI bike yet as I wanted to get as much info, such as yours, as I can. Your post is the first one I believe I've seen referencing turning off the O2 sensors. I used to do all my own wrenching but, when I was raising my kids, I farmed it out. Now I'm back in the saddle but there's this dadgummed EFI and on board computers to learn about. I was under the impression that the O2 sensors worked in conjunction with the EFI. Not so? If I understand what you are saying, I do NOT need the resistor if I leave the air pump in place and just neuter it. Correct?
