I got it home as quick as I could and took a look at everything. The only things I noticed was the tube connected to the bottom of my airbox (and maybe to the crank/cam housing - not sure) was loose and I also realized the I never attached one of the two metal bands that holds the airbox to the carburetor. The next day I fixed both issues, and also emptied out some oil (I noticed that I had over a decent amount over the max fill line when held upright), but now when I start the bike without choke my bike idles at 4-5000 rpm. And will occasionally stall after a while if I don't apply choke or mess with the idle screw.
Any thoughts appreciated
Also I forgot to mention that I have not noticed any smoke since the other day.

I would say either you have a vacuum leak (between the carb and the engine) or the choke mechanism is sticking either internally or externally.
A vacuum leak could be a clamp is not secure or even cracks in the rubber manifold. Spraying around that area with carb cleaner when it's idling and listening for a change in RPMs will tell you if you have a leak.
Your initial oil/smoke issue sounds like it was related to the over-fill, so you should be good after draining the excess.
