Oil In the coolant would point towards a cylinder/head gasket. Or less likely, a crack somewhere in one or the other, where adjoining pieces are designed to allow oil and coolant to flow. A wet, oily spark plug would point towards a gasket/crack in the heads, piston rings, or combustion chamber. And sooner than later, you'd notice a decline in engine performance. Zeke also mentioned the exhaust. If the engine is burning oil, you'd be looking for a grayish smoke. Maybe more so at idle than rev'd up? It's conceivable the engine's not burning oil in the combustion process, and is simply forcing oil into the exhaust. I hesitate to guess how much oil could accumulate in the "catalytic converter" part of the exhaust before being forced out the tailpipe still in it's liquid form. You could check for this "oil in exhaust theory", but IMO, you'd need to look and remove the exhaust header pipe from the cylinder head.
I've turned around and monitored my exhaust several times in the past few days commuting to school and back. While sitting at red lights I will check the exhaust and as far I can tell I notice nothing unusual from it.
On my bike, i'm losing oil since the beginning and I need to add some during the summer. Check the arrow on the picture.
Is there where I found some drop. It's near the oil filter cap, just more to the front.
It's not all the time but after a ride I can see some oil dropping from there. I explained this to my dealership and he told me that is probably the water pump seal that have a problem and need to be replace. I'm having now more 20k miles and the dropping is stable and is not growing. The dealership told me that many others bikes have this issue. You can check if is there you are losing your oil.
I do not see any after a ride to school to today, but as you said yours in intermittent I will keep an eye on it.
how much, oil are you using, topping up? did you take it back to the tech who saw no sign of oil burning? place a towel or tissue paper towel under it whenever parked.. if its burning oil you should see exhaust smoke..
also as mentioned spark plug is often diagnostic..
what engine parts were replaced by tech?
Losing quite a bit. Since moving in May, I changed my oil and have been topping it off when needed, and have four empty 1qt bottles. So, a lot...

I'm really not too sure. Honestly I do not think I was given any paperwork for the service at all. I will call tomorrow and see if they kept records for it.
I have not gotten a chance to remove any coolant or the spark plug yet, I am waiting until the weekend so on the off chance I mess something up I will have a couple days to fix it before stranding myself at home and not being able to get to school. I will keep you all updated when I get the chance.
