o2 sensor
Question, the Deluxe I now have is my first EFI bike that I have owned. I have little or no experience with them and I also have zero experience with an o2 sensor as well. So, showing my ignorance here, does my bike have an o2 sensor on it? It's a 2006 Deluxe with EFI. If it does, where is it at and what does it look like? Shoot, since I am here and asking, what does an o2 sensor even do? Where is it on a bike even if mine does not have it? I would like to know and learn more about it. I have heard of guys plugging it, I think. If a bike came with it can you do away with it? I want to go to some 39" 04 42" cholos this winter and I need to know so that I get the right pipes. Thanks in advance for your knowledge and sharing it.

Just bought an 06 Deluxe myself and was surprised at no 02 sensors because my 06 Street Bob had them. I too want to put the Cholos on this winter as well as a few other things(air cleaner upgrade) so I guess I am going to have to do some more research!
So anyone else that has put this exhaust on an 06 EFI Deluxe please help us out!!!
Not trying to hijack your thread, just glad I actually saw this before starting my own!

If you had one it would be in the exhaust stream close to the head. The ECM uses the sensor to correct A/F ratio. It would be screwed into a bung on the header and the other end would be plugged into the wire harness. If you dont have one then you order the exhaust without the bung and if they dont have one without a bung for your year you just plug it.
If you are going to run an autotuner or PC with wideband O2 monitoring then you need the bung.
FI has several sensors that help the ECM feed the engine correctly, the O2 sensor is after the fact diagnosis, the other sensors are upstream of combustion.

No pics, but if you bike has them, feel on the inside edge(s) of your exhaust headers from the cyl port to the pipes. O2 sensor(s) should be somewhere between these two points and they screw into bungs (ports) in your header pipes...should be two.

The Softail models didn't have O2 sensors in 2006 but they did in 2007 and newer. The Dyna models had them in 2006.
Thanks,

Hey Dude,
Below are pictures of the front and rear header O2 sensors. I apologize for the quality of the pictures.

Since a Samson tech chimed in on this thread, I should plug them. The pipes look and sound awesome. You definitely won't be disappointed with the Samson Cholos.

Thanks a bunch for the pictures Dude. It always helps to actually see something your not that familiar with. The technology between this bike and my last bike are like light years apart. It's fun tinckering and learning though and this is a great site to do that at.
