All bikes (samples at least),.. nowadays... are tested for emissions and noise to enter the US... Reg's are tight, and they are tested at sea level...
If you live at or near sea level,... you will be a bit on the lean side under normal conditions...
I live at... 2600 ft elevation, and lean sea level jetting suits this elevation fairly well... 5k,.. and you may even be rich with stock jetting...
Now,.. we throw in some breathing mods, and... it's a total cr@p shoot...
So,.. nothing inherent in the bike itself,... but just a generality of modern pollution and noise reg's... that effect all vehicles...
Air/fuel mix... is very much effected by elevation, temps, and humidity...
So,.. there is, at best, the hope of getting a decent average for your riding conditions...
If you're interested... See my tuning guide, in the Tech Section for advice on dealing your particular condition,... it shows some easy tests to guide you through each stage of carb jetting...
No one piece of tuning advice can apply to all,...so testing is the key...
