After checking your bolts, & if they are not at fault, take off the side stand & bracket, take your bracket along with your side stand to a local fabricator & explain the problem & show him the two offending items, you will see that where the side stand butts up to the mounting bracket, the soft aluminium of the side stand will be worn away a little, to rectify this add weld to the part the side stand buts up to & re shape till you get the desired lean angle. cost probably a tenner, darn site cheaper than a new side stand.
