First of all, when you try this for the first couple times, keep someone standby near your bike in case when something will go wrong.
Set the steer straight in line with the motorcycle. Grab with your right hand the passenger grip and with your left hand the left steering grip. Push with your right foot the stand to the ground until you feel the bike is stable on both points of the stand on the ground. Nothing can go wrong as long the pressure at the floor at both points is there. (The bike has to be stable of course!)
Now you can lean with your belly (keep your back straight) over the seat until you can see the right footrest.
You have to do the following actions at the same time:
Push with your right foot as hard as possible on the step of the centerstand. Pull has hard as possible with your right hand at the passenger grip Keep your steer straight.
Keep leaning over the bike a bit so your weight wil be in de middle of the bike.
The bike has to come up and lean backwards until it stands steady.
When it is still hard to manage it is possible that your bike is lower than original and your stand is still as long as original. Or the stand is another brand/type centerstand. Goodluck drive safe and don't let fall your bike.
This is not the tutorial, it's just a tutorial. You always are responsible by your self when what you are doing goes wrong. It is not the fault of following this tutorial.
