I suppose it's possible, but I can't say for sure. (I'm handy, but far from a mechanic) I've only had my Hawk since August and that isn't a problem I've had. There is a crankcase breather that vents into the air box. This would be the source of oil in the air box. I don't know what atf fluid would do in a place where motor oil belongs, but hopefully your piston rings aren't toast.

I wouldn't worry too much. Adjust the valves and do a compression and leak down test. Someone has been done on purpose before.

There is no choke on an EFI bike. There is an automatic enrichment made by the fuel injection system based on temperature.
Once you get the valves adjusted, if it starts I would let it warm up and dump that oil again. It will be contaminated with leftover automatic transmission fluid. Then put a fresh ~ one quart of good oil in it. If it is still not running right after valve adjustment and fresh good oil, you may have some damage from running the engine with ATF. Rings probably, but also rod bearings, which are flat. The roller bearings on the crank may have survived. OK, so ATF can run hot. It is a pump oil. Yes, maybe short run is OK on ATF. Maybe you even "cleaned" up the engine! But get those valves right and yes, another oil change. YOu definitely want good oil in there!

The optimal temperature range for transmission fluid is 175 to 220 degrees. Motor oil temperatures between 230 and 260 degrees. The ATF will lubricate just fine but will break down quick above 220 Degrees which is about the Temperature this engines run. ATF is a lubricant, otherwise every transmission out there would of blew up by now. lol Just follow the advise and do the valve adjustment before doing anything else.

so my best course of action because the engine is so simple is compression test then valves adjustment if that doesn't go well then engine rebuild? and if that doesn't work either?

Valve adjustment first, cold engine. Compression test relies on the valves closing and opening on time. If it starts, good news. But warm it up and dump that oil/ATF mix. Then get new fresh oil in there.

It looks like the clamp is missing on your exhaust....by where the kickstart folds up to.
