    Hey all,
    I'm getting a LOT of condensation coming from my exhaust to the point of it dripping from where the muffler connects to the collector not to mention the mist coming from the tip. In the pic, I had taken the bike for a 10 minute warmup and then parked and was colortuning. Not long of a runtime for this much condensation I thought.

    Any suggestions or problems with this. I think Fitz said it was because of ethanol in the fuel but I made sure not to get fuel with ethanol so I'm not sure what the problem is.

    Also, I'm occasionally getting fuel spitting out this "nozzle" at the end of the carbs. I'm guessing it is the return line for the fuel but I have nowhere to return it to. Suggestions about that? I'd love to hear it.

    I also have 2 additional "nozzles" between carbs 1 and 2 and 3 and 4 and I have no idea what these get connected to. My bike came with pods and the only line hooked up was from the tank to the fuel rail and the #3 carb to the petcock for vacuum.

    Finally, I can't get things running right. From what I hear it may be caused by the pods. The colortune seems to have an awfully wide "blue-flame" band so I richen it to yellow and lean it out till I get a nice blue, however when I do that and go to hit the throttle hard, it bogs before revving up. Any suggestions with this?

    Thanks for all the help and I apologize for the long post!

    No clue on the condensation but the nozzles should be overflows and usually have tubes connected to drain down like a battery vent.

    Also, if the carb was not jetted for those pods/exhaust combo, it's going to run bad until it is jetted properly. A lot of people think they can just drop pods in and go. Without fuel injection, you have to retune the carbs.

    The PO did NOT jet the carbs. Plugs looked brand new when I pulled them and when I threw in the jet kit I pulled the original needles and jets out. The mixture screw caps were removed however, so they did mess with the mixture with stock jets.

    I did rejet the carbs with a stage 1 from K & N. I started the needles in notch #3 and dropped them to notch #5 right now. It looks like this keeps the carbs rich enough but if anyone thinks it will help to drop the needles to the richest setting(notch #6) I could do that, I'm not sure what the advantage will be, though. (I'm new to jetting myself).

    Condensation can be heavy on particularly humid days (upward of 80% without a drop of rain). So long as the condensation clears after 10 or so minutes after start-up I wouldn't be concerned.
    Of course there is the normal amount of water generated during normal operation but I couldn't hazard a guess as to what normal would be in your case without knowing the air temperature, weather conditions, humidity etc... on the day that you performed your maintenance. I know that here in southern California, even living next to the coast I don't see water dripping from the exhaust after warm-up even with the high humidity here.
    If you don't find evidence of condensation contamination in your crankcase, I wouldn't worry about it.
