If you run the bike before checking the oil, the bike MUST be at running temperature to ensure the oil drips down to be correctly checked.
Running it for a minute will NOT achieve this. (if you MUST run it before checking it, let it warm up until the thermofan kicks in, turn the bike off and wait a minute for the oil to settle)
That's why I recommended riding it and then parking it on the centre stand.
The oil will then be at the correct level - and it doesn't matter if you check it stone cold - as long as it was parked when hot. (actually, stone cold will be easier to see on the dipstick as the oil is thicker.)
Cheers,
