Starter problem.. it started! White smoke rom right carb?

One more thing, the bike had been sitting outside for awhile before I picked it up.  When I was taking everything apart *I noticed some water in the air box.  I changed the oil which was pretty nasty.  Maybe water made it down into the intake and thats why its smoking white?  I checked the dipstick again after I got it started and the oil looked awful murky again so Im in the process of changing it again now.  Maybe it will help?

My initial thought was that it could be moisture condensation/dust/pollen. Had it been me, I probably would have let it run for another couple minutes to see if it stayed the same or got worse/better.

After thinking about it, I think it is moisture.  When I removed the carbs when I first got the bike there was some crud in the left hand intake on the valve which I cleaned out but the right side looked good.  When it was parked last the left intake was closed and the right was probably open allowing any water to just go right in.  The motor was never seized or stuck at all so that's good.  Should I put a little Marvel Mystery oil down the right spark plug hole and let it sit over night?  Or will running the motor and changing the oil a couple times get any remaining water out of the engine?  Thank you very much for taking the time to answer my questions.
