O2 sensor eliminator — why?

[Dharma_Jones93_imp]

I've experienced this surging on other bikes. For myself it has either been one or more of the following: O2, TPS, or Intake Air Sensor. They generally don't emerge as check engine lights either, they're often "hidden" codes that you need something like tuner pro to reveal (or factory diagnostics). In my experience it's usually a wiring malfunction and not an issue with the sensor itself. When faulty it sends bad info resulting in the ECM trying to constantly readjust. If you bypass the faulty sensor (via an eliminator) you're only temporarily fixing the problem. As you add mileage to the engine the ecosystem will change, requiring adaptation to maintain homeostasis. Without this sensor, the ECM will not fully be able to adapt resulting a reappearance of the original symptom, that is until you replace the sensor.

Judging from the number of complaints there may be a factory flaw in one or more of these sensor systems. Could be a good idea to collect production dates, etc to locate a bad batch of sensors.
