    Exhaust leaks can cause a lean condition. Does it pop or backfire? Sounds to me more like a pilot circuit or sync issue.

      yeah it backfires a lil

      it only backfires or pops i should say when i downshift hard, i can downshift without the popping unless she hits 4 grand plus

        Are your idle adjustment screws still capped off? If not try backing that cylinder out a half a turn. Are you refering to #3 as the right one sitting on the bike?

          yes No#3 is inside on the right.

          it idles a lil bit high, not much, should be 1100, it's at 1400 cold 1200 when she warms up it fluxs a lil in between. after ride tommoorow i will check the plug again, it's about 3 hour ride, if it's still white i will try and drop the idle a lil bit. will turn all the screws in, and back em off turn and a half i think. thx.
