Question Oxygen Sensor Replacement

I have a 2007 fuel injected Springer with 30k miles, big bore, V&H pipes and S&S gear cams. On a recent trip, on three separate occasions, the bike simply died, eg, not run. I originally thought a fuel vapor lock but, after coasting to a stop and powering-off, the bike started and ran again ... until the next incident.

The DTCs read P132-0 and P152-0 indicating the Front O2 sensor high and the Rear O2 sensor high. I figure the corrective action will be replacement of these sensors.

Is replacing the O2 sensors relatively easy to do or should I give serious consideration to taking the bike to a shop/dealer? Are there any recommended O2 sensor replacement kits others have used and recommend?

I do not have any special tuning or adjusting equipment ... just a novice's set of tools.

I classify my mechanical skill set as 'ok' bordering upon competent: basic tune-ups I can accomplish.

Thank you.

Repalcing the O2 sensors is very easy. You can get a slotted socket from J&P cycles that will fit the sensor, or you can use a open end wrench. The wiring from the O2 sensor has a delphi plug approximately 3 inches from the sensor. Simply unplug the wiring and then remove the sensors from the pipes.

Harbor Freight sells a socket pretty cheap.

The front O2 sensor is under the plastic cover that is below the oil filter on your bike. the rear O2 sensor is underneath the oil tank, accessible from the right side. See attachment.

The front plug is easy to access, just unscrew the plastic cover. The rear plug is in a tight spot. Easiest is to take out the battery and the plastic bit the battery sits in (if that's on your bike at least) then you can unclip the plug from the oil tank which makes it easier to disconnect and re-connect. After instal, just clip back into the oil tank.

I guess I would ask why both O2 sensors are bad at exactly the same time. Your bike is running rich, could it be the ecm?

Whenever i come into some cash: Ride Wright Fat Daddy's and Wild 1 550's. And it still won't be close to done.

Thanks to all for the responses.

As a next step, I'll look at the sensors for any indication of contamination or need for replacement. I an always replace them with a HD sensor.

Optionally, the LC-1 Wide Band O2 upgrade kit looks quite interesting. Anyone have any feedback on this product?

I will have to consider an ECM 'SNAFU' as well and will speak with the local dealer's service staff today.

Thanks to all for the suggestions, inputs.
