stupid question perhaps - oil change before/after valve check?

[Inhouse Bob]

hehe thx

so it would not matter if I already changed the oil and he performed his maintenance?
I ask because I am not mechanic and perhaps there is a certain order of things? like changing the oil as a last step after you have done a valve check?

I don't believe any oil is lost in the checking of valves, but maybe someone else with first hand knowledge can confirm that. I have not done a valve check on this bike, just others.
