O2 sensor location

[Kevin Cease]

I hate I have to post every time I do something but I’m really trying to learn. I got my ECU flashed by MM and note says unplug the o2 sensor. But where do I locate it? Thank you in advance. Gen 3

If your not using the woolich auto tune kit then the factory o2 gets disconnected. If you have a plug great if not just unplug it and leave it in the exhaust till you get the plug for the exhaust.

Do NOT leave the factory o2 connected by any means or you will cause huge issues as this can lean the fuel tables out and nuke the engine.

Thanks I will not leave it. I ran it for a second in neutral but no driving I will take it out asap

look under the bike and you will see the o2 sensors. trace them up the frame and unplug them. if u want to remove them from the exh you can buy 2 12mm o2 plugs.
