My scooter does this, in my case it's the center stand. You can try a spray lubricant on the pivot point.
I haven't found a permanent fix for it though. Tried many different kinds of lubricants (WD-40, liquid wrench spray lubricant, lithium grease, engine oil, dupont chain lubricant) with or without disassembly, it always comes back. They all seem to work equally (not) well.
