Sorry for such a dumb question but I am concerned.

So i checked my oil after my 600 mile service, and i would say it was inconclusive. There was oil on the stick, but more all over it after following the instructions. I asssumed it was because of the bubbles in my oil tank you can see if you shine a light after it has been run. Also could have touched the neck.

So i have been smelling hot/burnt oil after some ride, so i decided to check it.
followed instructions, running the engine for 30 seconds. Again bubbles in the oil tank, all over the stick. I wiped it clean, and after several attempts, nothing shows up on the stick after the ubbles have gone.

I am used to checking the car with no problem. Should i run the engine 30 seconds before checking?
also, i can see oil in there, if i add some, how much should i start with with such a small tank and no fudge factor.
