Hi!
It's hard to say, because it's dirty all over. Is the little plastic bottle also full? Why don't You clean your engine first, wipe all the dirt off and then it will be very easy to find the leak.

I agree with tehnis: clean the engine and the source of the leak will be a lot more obvious. Could be the clutch cover gasket perhaps?

Never argue with a fool: onlookers may not be able to tell the difference.

The little plastic bottle is full. Should I empty it out? It was full when I bought the bike last week. I will clean the engine and post some new pics.

Yes, empty the bottle. It collects oil that is vented from your crank case breather and into the airbox. Open your airbox and see if it has a bunch of oil in it too.

Yes! That's why I asked
Seems like we found the possible leak reason

Sorry for oftopic, but is this Your first experience with VN800 engine? Make sure Your valves are adjusted! Never relay on previous owner.
If any questions, don't hesitate to ask.

Yes tehnis, this is my first experience with any motorcycle engine lol. I did do research and knew these engines needed valve adjustments but I'm not comfortable doing this process and will take it to a mechanic. Hopefully it's not more than a couple hundred bucks

as your bike motor pushes out oil mist from the crankcase, the blowby mist goes to the air intake box, and suppose to be recycled back into the intake for combustion, excess oil will run down the inside of the air box and down a tube the a little bottle at the front of the motor, if it fills up , the oil can back up and overflow around the motor, maybe that's what you see, you may be seeing backed up crankcase oil mist from the full bottle

Thanks btom and all for the help so far. I'm going to empty the bottle, run it for a few minutes and report back with what I find.

So yesterday I emptied the little plastic bottle and checked the air filter, sure enough it was covered in oil. Looks like once the oil in the bottle filled up it starting backing up in the air filter and cover.
