Air/fuel mixture is important to optimize combustion. If oil is making it's way into the combustion chamber then the mix would consist of oil, fuel and air. Would it not effect the efficiency of combustion? I think the oil added would!

Yes.
If it's lost as much as 20 horses I think you may well see a smoke screen out the back?
The graph reads like it's got low compression, nothing else would give such a consistent loss of power across the board. IMO.

Is it not the fact that you have ran it in over 2000 miles and gave it an easy life? A leaking valve stem seal would not cos a lack of power unless it was leaking a lot of oil. im going with the fact that the engine has had a very easy life and isnt properly loosened up yet. i bought a new s1000rr in 2014 and had it off the 9,000 limiter from day one. it made 182 bhp on the dyno. away and book a few trackdays and dyno it again :joyous:
I doubt it - with modern tolerances the engines either work or don't.

My first bike in 2010 gained 10bhp over the first year(and the reading was not biased by the dyno/time difference etc.).
This is the power run I had done at Powertech.
My bike's repaired, now powering a whopping 193hp.

What was the problem with it?
Two valve stem seals were leaking. Apparently

Air/Fuel ratio is much better now.

Hmmm! Glad they've sorted it for you HP. As you may remember, I wasn't convinced at the time and to be honest I'm still not. But fair dos, if that's what they say it was, who am I to doubt them. Like I used to say when I was working, "you learn something new every day". The main thing is it's done now and you're happy again. AJ's are good aren't they!
