Its much easier if the bike does'nt have the flip up 'suicide stand'.The single swinger bikes are a doddle to get on the rear stand;
As mentioned before insert the stand pin into the spindle with the bike ion the sidestand.Move to the rear of the bike and gently lift it off the sidestand while pushing down on the paddock stand at the same time.If you have a good quality stand like the Ducati FG,it should go on easy.
To remove from the stand;
Stand on the l/h side of the bike,(gearchange side),and grip the l/h handlebar and rear subframe under the seat.Wedge your right foot under the nearest wheel of the paddock stand.Gently lift the bike up and forward just as you would with a centre stand.Once the bike is on its wheels,put it on the sidestand and remove the paddock stand.
Only ever use a front stand with a rear one.Some front stands have locating pins,others cups and some have a two pin bracket affair that goes under the fork legs.Should be just a matter of locating the pins,cups,etc under the forks and pushing down on the handle.
As H mentioned get someone to help you while you gain confidence,......or pad your garage out in old mattresses!
