Learn to drive whellie with a small risk

Hello, I have now driven a season with my bike and think that I can move it quite well on the road. Now the attraction is to drive a wheely over a few meters. Only how do I start with it, and so that I keep the risk low? Maybe you can post me your beginner tips and general tips. P.S.: under the search I found nothing. I have done a small, very small power wheely from time to time, but how do I do this with 5 0 or 80 things? Do you stand up? Do you just turn up the tap from 9,000 rpm on? Or do you pull on the handlebars? How should you start slowly with it? Do this naturally on blocked terrain Evtl you have useful tips for me. Ohso, referring to the motorcycle: GSX-R 750 K4 Thank you very much already
