    Afr wonít read right.

    Iím having trouble figuring this out. My afr is never consistent when I turn it on and within 10 min of riding it shows accurate 11.1-11.5 cruising. The longer I ride it starts not registering and is off the charts lean. Like 17+. Itís obviously not that lien otherwise it would not work but Iím trying to dial it in and cannot with an inaccurate gauge. I have tried replacing the sensor and replaced the O2 bung holder to the riva one and it still does the same thing. After letting it rest for a few, I can turn it back on and it will show fine again.I canít get over how In accurate it is. At this point the only thing I could think of is that itís a faulty gauge or how I have it wired but it powers up fine and it is wired to a 12 V source in the gauge cluster. I originally thought it was the aqua sport bung holder that was the culprit and changed it to the riva one as I had that on my last ski without issues.

    On a sidenote after some time on the ski my right foot well gets oily and slippery. the only thing I could think of is that the drain tubes for the foot well is back siphoning from the hull and has oily grime in it has anyone experienced this before?

    Dan, in the past I used the Bosh 4.2 O2 sensors in my skis running them for several years without replacement.
    But now on my 19 FXSVHO and my 09 FZR I use the Bosh 4.9 O2 sensors and they don't last me 2 rides before they go bad.
    Now I will test AFR's if I make a change to the ski and remove the O2 right after I check the AFR's.
    Is anyone running the 4.9 O2 sensor for extended periods without failure?

    I used to have the same setup in my 14í and never had an issue. I left it in all the time.

    The right side footwell is full of fuel to most bizzare thing ever.

    I use a 4.9 and in my sho with it in the manifold bung would go out after a ride.

    in this SVHO I have the riva adapter and got 2 rides so far out of it. I also have the heat sink for the sensor to help protect it from the water

    If that’s rich then, my gauge isn’t working at all. I mean, am hour into my ride it started reading 17+ there is no way.

    White plugs are lean... darker is rich.

    the pic I posted was reading 12.2-12.5 WOT
