I'd never run an unloaded engine above 2K ... but that's just me
Not to be an anal retentive enginerd but TECHNICALLY what you describe is not 'bleeding'. Bleeding is the process of opening a closed system to allow air to escape.
What you describe more closely resembles 'burping' like you would do on your cooling system.
Here, lemme help you out -
I'd absolutely do what you describe though ('cept at a lower rpm) before taking the beastie out on the road.
