    A little carb Info. Please!!!

    I have a 1980 1100ET and the carbs seam to be running a little rich. Let me explain my situation. I have a stage 1 jet kit with a V&H megaphone header and the orginal air box with a K&N High Flow Air Filter. I have also changed my coil packs from the orginals to a set of Dyna's that I purchased from APE. After all of the work that I have done I still have a small trail of white smoke while Ideling. I belive I am running a little rich but would like a little more Info. if possible. At this time the only thing I have done to the carbs is advance the spark pluge gap and chanced the main jets to a set of 110's. At this time it runs better than it ever has before but it still seams to have a flat spot comming out of the gate and the white smoke is a problem that everyone makes comments about. Since I am not a good carb. guy I am not sure where I should go next. I know that I should adjust certin jets but I just do not know where to go from here. Please could some one let me know where to go next.

    Thanks for all of your help!!!!

    My feeling is that for an 1100 with a V & H 4 into one, 110 mains may be a little on the lean side. 110's are about what you would run on a 750 with a 4 into 1. What color is the center ceramic on your spark plugs?

      Correct me if I am wrong, But I thought that white smoke implied oil burning, while black smoke indicates rich conditions, maybe the carbs are not the issue,

        The plugs are running black with a little carbon build up. Not bad according to my manual but again any info. will be good. I just finished replaceing all of the gaskets on my top end and after inspecting everything it still seamed to be with in the tolarances. I do not think I am burning oil because the smoke dose not smell like it.

          Valve Guides, or Piston Ring Blowby, just by the light smoking @ idle & Plug info you have given.

          Do a Compression check and then a leakdown.

          Rich = Black Smoke, BME.

          Peace,
