    Just installed the Premium tuners kit on my 80" Evo Bobber. It runs so much better it is hard to describe.

    I am having two issues.
    1. After installing the kit the mixture screen does not seem to make any difference in the idle. Can't get it to run rough even turned all the way in.
    2. When shut off, petcock off, if I stand the bike upright raw gas drips into the throat of the carb at a pretty good rate and soaks the air cleaner.

    Obviously I did something wrong. Suggestions please?

    Thanks.

    I'm assuming that the fuel is coming up through the needle jet around the needle? Fuel flowing into the carburetor with the engine off is an indicator of the float or float needle valve being stuck or worn. Typically shutting off the petcock valve stops this unless there is a faulty petcock.

    Regarding the mixture screw not having any effect on idle, you may be too rich on the pilot jet. But before changing anything I would fix the float level and replace the float needle valve if at fault. Excess fuel flowing through this circuit will obviously be adding too much fuel even during idle and be giving a false reading during tuning.
