White smoke/ oil out of the airbox

I just replaced the oil filter, put in the recommended amount of fresh oil, cleaned the carbs, and cleaned out the gas tank. Finally went to start it today and it idled for about a minute, then spit out white smoke like it was born to do it, and oil started POURING out of my airbox vents. It's on a 1980 KZ750 H model, with the inline 4. I'm so pissed right now, but need your guys' help. What the fuck just happened?

Would also check for gasoline-contaminated oil in the crankcase.
Do the sniff-test, and also physically examine the oil.

Perhaps the recent carb work resulted in substantial volume of gasoline rising up into the carb throat (for whatever reason) and ultimately making its way into the crankcase.

Good Fortune! :)

do you think you switched the oil with the gas?
