Bluejay's right, but work out a ballence point that you are comfortable with and find a good place to put your right hand 'limited as it is'.
Hold the handlebars straight with your left hand. Place your right hand on the grab rail at the back of the bike.
When you first put the stand to the floor with the ball your right foot, rock the bike gently side to side to make sure that both feet of the stand are on the ground.(Now the bike is upright and ballenced) Now whilst pressing down gently on the stand with your right foot, rest your right knee against the side of the bike. Now lean your sholders over the saddle and stand up on the ball of your right foot staightening your right leg and lifting your left foot off the ground ( as long as you are pressing down or standing on the stand and both it's feet, and both tyres are on the ground, and your waight is far enough over the saddle, the bike can't fall over). Now, you should be standing with the ball of your right foot on the leaver arm of the centre stand, right leg straight, left leg off the ground, left hand holding the bars straight 'Not turned' right hand holding the grab rail, sholders leaning over the saddle, your head looking at the ground on the other side of the bike (all ballenced and acrobatic-like) Now with your right arm straight pull the grab rail towards you steadily and firmly (don't try to jurk it) at the same time press down firmly with your right foot ( Do Not try to pull with your left arm, just hold the bars straight) 'Now here's the magic bit' Lift your head up and look at the sky whilst at the same time straightening your back, pulling with your right arm and pushing ALL your waight down into your right foot, Bonk! the bike is now on it's stand
Go have a beer you've earned it.

Unless of corse you want another go
