    Is water supposed to be in the downpipe where I mounted my oxygen sensor ?

    I finally mounted my lc-1 afr and after initial startup water began to trickle around the oxygen sensor threads. This on a 07 ultra 250x. I pulled it out and put teflon tape on the threads. My question is, the inside of the pipe where the sensor tip is, should that area be dry. Maybe I have a gasket letting water go from the water jacket into the exhaust port. Otherwise, I don't think the oxygen sensor will warm up enough to give an accurate reading. I did have the entire exhaust off but all gasket surfaces were cleaned very well before reinstallation. I have no leaks externally.

    Lightbulb okay

    Thats what I thought. Luckily the ski has only run a few minutes. Should be okay. thanks killa. After looking at the service manual drawing, the water should come out of the holes at the downpipe right above the silicone coupler. Am I right.
