white smoke is a sign of incomplete combustion of fuel. (or in my case when I got my bandit, water in the tank) So what may have happened is there was junk in one of yur jets or instead of having the petcock on the "ON" or "RES" position, it was set to "PRI". May want to double check that one. I think it is consensus on the board to go about 2.5-2.75 turns out to start. You did do a good think on checking where you were before you started tearing everything apart and verifyin that you were at 3 turns out. I would try to go about 2.5, take the bike out and get'er real warm and then fiddle with the screws again. Your prolly just running a bit rich, no prob. But check your fuel too.
