    GPRSHO blowing O2 sensors

    I have a GPRSHO with an 08 motor. I can't keep an O2 sensor alive to read my afrs. I am using the Innovate MTX-L. What does everyone else use? Any ideas how to fix this problem. Temps getting colder up here and just want to be safe.

    Usually water in the exhaust stream is what causes the sensors to go bad.

    It's tapped in the muffler. There is a place there from the factory that I thinks most guys drill and tap.

    Yea there is a place that is in the manifold from the factory. Mine is mounted there and I'm using a mtx-l and havnt had any problems so far! Have u seen signs of rust or corrison on any of the sensors u have taking out?? My friend had that problem and he ended up have a crack in the water jacked part of the exhaust manifold and it was blowing water on the sensor and keep fouling them out after just a few mins of riding!
