    So basically here it is I re-jetted my bike and was running alot better road it for a couple days and it was doing great! I left to go out of town for the night and when I got home the next day there was a puddle of gas under the bike!! I looked to make sure everything was connected and when I pulled the bike out of the garage I saw fluid dripping from one of my air pods...I took all the pods off and the fluid that was in one of the pods was gas!! now I took the air filter off and seeing if the extra gas would evaporate over night....Anyone have this issue or know what it could be? I also did get gas yesterday and filled the bike up, if that makes any difference :? Please help me! I was looking forward to riding it this week

    You have a stuck/sticking or mis-adjusted float.

    Float level adjustment is precise and critical; as is proper float operation.

    There is a whole lot more to those carbs than the jets.

    Take the carburetors back off the bike.

    Remove the float bowls.

    Remove the float pins, floats, float needles, and clean everything. Polish the float valve seats or replace if pitted. (The float valves sticking or not sealing are the cause of your actual issue.)

    While you're in there, you may as well clean the carbs thoroughly since you're going to have to anyway. Replace any dried out or flattened o-rings and seals, gaskets, etc. Check the o-rings on the pilot screws, and the seals between the float valve seats and the carb bodies.

    Reassemble, and "wet-set" the float levels to specs using fuel and the "clear tube" method. The spec only has a 3mm "window" so precision is required.

    At this point, your actual problem will be solved; but there will still be some work to do to get the bike to run right.

    Continue with the rest of the carb service as shown in your service manual. (This is a 30-year old bike. You're going to need a service manual if you don't have one.)

    Bench sync, then return to bike and re-do your vacuum sync, etc.

    The above WILL fix it. There is no quick fix. You have to do the carbs right, then adjust and tune properly.

    Especially
    with intake and/or exhaust mods.

    What I've noticed is that for whatever reason, the pins that hold the floats in will bind on older carbs. I don't know if they bend, or get corroded, rusty, or if they use Jedi force, but sometimes they just stick for no apparent reason. I've gotten many a flooding engines home by simply tapping the bowl with the back of a screwdriver...

    fitz is right though, if you're going to do it, do it right.
