I had an opportunity to try to assist a fellow EV owner the other day.
When we tried to put his Z20A on the Center Stand, it went past the stops.
You should inspect the stand and the stops and ensure everything is correct.
On his Scooter, the stops were square blocks welded to the frame. On one side,
the weld beads actually made a ramp for the stand bracket. There was evidence on both sides of the brackets being forced out a little further every time the scooter was put up on the stand. On this scooter, when the brackets went past the stops, they were actually deformed. I pulled the stand and was able to straighten the brackets a little but they are not thick enough or strong enough metal. Also, the bushing that goes thru the bracket that allows it to rotate is actually longer the the metal is thick. The bracket have at least 1/16" of play. This also contributed to the brackets riding over the stops. I advised the owner to try to find some washers or spacers that would take up some of this play to help keep the brackets from riding over the stops.
