The US models don't have one. If you want to do something with the factory O2 sensor, you will need to purchase a european bike.

If you have a sensor it is located in the slip-on exhaust, si you've should have noticed that.

When you follow the cable from the sensor, it will take you to the left side fairing. You can unhook it by loosen the connector (succes with that one) and there you have to plug in the O2 sensor.

Here's a pic to show you where its at:

Nope, there is more than 1 normally (on euro bikes at least, like mine)

If you follow the wire it should go to a "Lambda"-sensor which is plugged in you're exhaust.

My bike has a Taylormade, which is an US brand, so there is no hole to put this Lambda in, because normally US bikes dont have that.

The O2 sensor is needed for Euro bikes wich have slip-ons without Lambda-sensor holes in it.

where in the exhaust is it found?

i was told by dynojet that i needed an o2 sensor eliminator because i have a CA bike

They didnt send instruction on how to install it??? They usually do. I didnt think the US bike had an O2 sensor either. I think you got ripped off my friend

Its almost impossible to adjust anything on a dyno without the bike having a O2 eliminator. So i think you dont need one...

I'm gonna have to agree with the others that have said the US bikes INCLUDING CA models DO NOT have an O2 sensor. The service manual has no mention of an O2 sensor, and it always points out when there is a difference between CA models and non-CA models.

The only additional item Ca bikes have is the fuel vent canister. There is no exhaust O2 sensor on any new US CBR1000RR.

If you want to use the autotune function you need to have a bung welded on to your collector. The inlet of your slip on is too short to accommodate one. Any muffler shop can do this for you.

Add here.
