Lars, I am glad the smoke cleared up. I am not sure I would add the 11th quart of oil, because I wouldn`t want to risk overfilling again. My rule of thumb is that I like to see the oil dash guauge needle at nine o clock exactly when warm. Then, you can monitor your oil consumption, and when the guauge is back down to 6 o clock, you know it is time to add another quart.

For cleaning the airbox, all you need to do is remove the straps, remove the air intake, remove the air filter. That gives you access to the inside of the airbox, where you can clean the oil on he walls if you see any. No need to remove the airbox.
