Perhaps the side stand should be looked at.
Tony - you have a 'surefoot' that has been set so that your bike does not lean that far as I deliberately set the leg longer.
But it is a good point. Please check your stand for wear. My stand broke, and caused some unfortunate damage to the paintwork on my bike. It is the stand itself you need to be looking at, where it connects to the frame, rather than the frame itself. If it is very wobbly, then it might point to a potential issue.
