O2 sensor eliminator — why?

[Gumby 1100_imp]

I cannot understand how leaving the O2 sensor disconnected would cause it to fail. I am under the impression that the sensor places a certain amount of resistance across it's leads according to conditions in the exhaust flow. Seems to me that the sensor will continue to operate as normal it just will not be read by the ECU. Someone enlighten me if I have this wrong as I have little understanding of these systems.

I was told by the owner of Redline Superbikes, the main supplier of the Eliminator Plugs, that the O2 Lambda Sensor should ideally be removed as it will eventually foul beyond use. That's why he provides a Cap Screw and Washer in most of his kits.

When the sensor is in circuit it is initially preheated which burns off a certain amount of carbon. It may be ruined if left in place but not left in circuit for extended periods of time.
