    White Smoke after Carb rebuild/cam adjustment

    What does the white smoke mean after a carb rebuld and cam adjustment? It's coming from the 3-4 exhaust (4 into 2) and popping, i think, moderately - every 3-4 seconds. Prior to rebuild and adjustment this was not happening. I need to check my plugs but have not had time to yet. I haven't adjusted high idle yet either, once again, little to no time for the next two weeks. Air screws out 2 turns and fuel screws out 1 turn. 1979 GS850.

    Are your plug wires on the right plugs?

    Left coil should be on #1&4, right coil should be on #2&3.

      The wires still have the numbers on them. I did check to make sure they were on the correct cylinder - left to right 1-4. I'll check again.

        What do you mean by cam adjustment?
        Did you add slotted cam sprockets?
        Popping usually means a lean condition, so did you replace:

        1. O rings in carbs
        2. O rings between head and carb boots
        3. Carb boots?

          replaced all o-rings aboved mentioned above. New intake boots to manifold, not air cleaner boots to carbs though.

          i changed some shims out to specs - .03-.08mm.

          It's been running leaning inbetween the carb rebuild and cam/shim adjustment. I'm going to try the high rpm adjustment now. It will not idle without near full choke. I'll be back when finished.
