This is the sensor formerly installed in the front cylinder.

Here's the one from the rear.

And here's the Power Vision reading now that I have swapped them.

*edit* issue resolved per Brian

That is correct -- or at least it's in the process of being resolved. Brian quickly shipped out a replacement O2 sensor. I'm hoping it arrives today and then we'll confirm the resolution for sure. Brian was very helpful. The customer support from Fuel Moto was just what you would hope it would be.

Leaving the signal cables routed as it is.
The cables aren't long enough to allow a swap of the cables with the O2 sensors remaining in their original positions. When I swapped the sensor positions I also swapped their connections. That was the whole point of the swap really. I'm sorry if that wasn't clear.

So to be perfectly clear . . . just in case anyone is reading this looking to address a similar problem, the swapping procedure was as follows:
  1. Disconnect front O2 sensor from cable.
  2. Remove front O2 sensor from exhaust header
  3. Disconnect rear O2 sensor from cable
  4. Remove rear O2 sensor from exhaust header
  5. Install O2 sensor that had been in front ehaust header into rear exhaust header.
  6. Connect that O2 sensor to rear sensor cable.
  7. Install O2 sensor that was previously in the rear exhaust header into the front exhaust header
  8. Connect that sensor to the front sensor cable.

Hopefully that eliminates any confusion.

Just to close the loop on this discussion (pun intended), the new sensor actually arrived on Wednesday. It just went to my partner's desk instead of mine so I didn't see it until yesterday. I mention this to further highlight the great service from Brian and Fuel Moto. He shipped it immediately and by next day delivery.

Installed it this morning and all readings are normal. Thanks, everyone, for your help. Now the only reading that is a problem is the thermometer! Oh well, that's why they invented coats, gloves, and full face helmets!
