I know loaded question but here goes, I added Redline fuel additive cleaner,( second time) and after 20 miles bike started missing and going to limp mode, Checked codes and found p0134 p0154. I could clear but still comes back. I drained fuel tank and put in clean fuel to no avail.My question is I get part number off bike 31869-10 but it doesn't match what dealer has 27809-10, do I trust their part number, and should I just change both now to be safe. It already ruined ride planned for fathers day and we plan on heading to Hollister in a couple weeks.

The part numbers for your oxygen sensors are 27809-10 Front, 27729-10 Rear... 

Where did you find the part number 31869-10?  I'm not familiar with that part number and a quick search told me nothing...  Are you sure that's not an OEM manufacturers p/n vs a MOCO part number?

The Harley part numbers are assembly numbers that include the harness and connector, and since the front and rear harness and connectors are different you need a different Harley part number for front and rear.  See sadunbars post for the two correct numbers. 

In the future, don't use any additive that doesn't specifically state on the container that it is sensor safe.  There's a lot of stuff on shelves that were originally formulated before O₂ sensors became common.

That part number is what we got off the diag screen as you filter through the prompts, first the error code then the part number.and yes Jerry I wont be using that again, it seemed ok the previous oil change but no more.

Are you running the PC-V with the wide bands? I see PC-V in your signature. If you're not running their auto tune unit with wide bands you should have the little connectors to plug into the wiring harness to tell the ECM not to trigger a code for O2 sensor.

The part number that comes up after you cycle through the DTC's isn't the number of the of the sensors, but instead just identifies which electronic module the information is coming from.

Bikes in INDE shop, swapped out 02 sensors, did not help, so they also tried engine temp sensor , still getting same codes and also p0031.Any ideas. We are planning on a trip down to Hollister next week for the 4th, so Im now getting a little nervous

I don't believe its auto tune as it was mapped, dynoed etc.and its been running ok that way since spring 2011.

P0031 is the voltage supply to the heater for the 02 sensor.  I have not worked on this issue on a motorcycle, but I have on a car.  Same code same problem...

Harley describes the cause for this code as:

A short or open in the heater circuit in the sensor
A failed O2 sensor heater
Wiring/connectors broken/frayed leading to sensor and/or relay
Failed PCM/ECM


Again, my experience was with a car, but this is what I learned during that episode.  If the O2 sensor heater circuit voltage is low, you'll need to unplug the sensor and with ignition on/engine off and (using a voltmeter) check for 12 volts at heater circuit feed. Is it there? if so, plug sensor back in and back probe the connector and see if you still have 12 volts.  If so, you'll need to start checking the ground circuit for continuity. If you don't have 12 volts at all with the connector unplugged, then check your appropriate fuses.  Usually heater circuit problems are because of a faulty circuit inside the sensor itself and usually replacing appropriate sensor fixes it.  But, you said you've already installed new sensors, so it has to be the wiring that is suspect.   

I suspect a non functioning heater circuit could also cause your 02 sensor fault codes to appear, but I don't know this for fact...it just seems like a good possibility.  At any rate, I suspect your issue resides in your fuse box or wiring, and not with the sensors themselves - or with your ECM...

Thanks for the help Jim Hd-dude and Sadunbar. Ended up being PCV went bad. Will not go there again.

Stick with the TTS, There's nothing to fail!

TTS if you have a good dyno tuner near you, TMax if you don't would be my suggestion.
