You might want to inspect both the ground contact points for excessive loss of metal. Over time, concrete does a good job of grinding off the rounded portion of the contact patch. My R100S was a bitch to get on and off the c'stand. There were open holes worn through at the contact points. Stand off, weld weld, grind grind, all better now.
Also, inspect the stand to chassis contact points. Both of them. That's the other problematic wear area.
When you remove the stand for possible rehab and are ready to refit, you'll be faced with stretching the springs to catch their anchor points. All but impossible unless you stick washers or pennies between the coils which will lengthen the spring and reduce the amount of blood loss.
