ewwww not good at all hope it isnt too late but it prolly is. start flushing the oil change it over and over till the oil is clean and use different oil filters also and pull the plugs to get all the water off the top of the motor before hand
dude it's not too late.
As long as your oil is clean run it a bit. They sometimes smoke for a bit after the incident. it should clear up. Seen it several times.
Sometimes it takes a few rides but it should stop. im assuming it's light smoke.
phreebsd is right but usually that is the seafoam and what not burning off, but i could be wrong just none of ours ever smoked really cept for my buddies which didnt get sunk and we will let yall know asap what his problem was its going to the dealer in the morning
just make sure you keep an eye on that oil. change the filter make sure everything is good and clean. and re-route that crank vent too if you havent already. That will keep it from pukin oil into your airbox.
I noticed this as your title. "09 bf750 still smoke from puking oil up into the breather box" I got with you a few days ago. If you are finding oil in your air box, that will cause it to smoke as well. Try rerouting the engine block breather and clean the air box. See if that works.
I'm suprised that your having this much trouble in that little amount of water. I've hit deep skidder track ruts full of water at full speed, burried her up to the headlights in swamps & rivers, slow rolled it in a water hole and stopped it dead at full speed crossing a river and never had water in the oil.
Check your duct work, air breather, etc.....there is something loose or not routed properly.
