The recall involves replacing the pivot bolt for a slightly longer one.
The threaded part of the bolt is very slightly too short, this means when the lock-nut is tightened there is no thread protrusion sticking out past the locking part.
What happens is the lock nut can come undone due to the lock not gripping, this in turn allows the bolt to slacken, caused by the friction on the shoulder grabbing the bolt and slightly loosening every time the side stand is used until eventually coming out altogether.
If you check at the back of the pivot bolt you will see and feel the end. If it needs replaced you will feel that the bolt end is flush with the nut.
The new bolt is 1-2 threads longer and will be proud by this amount when fitted. Therefor fully through the locknut.
1.5 to 2 threads would be the industry standard for protrusion.
I had this recall done recently and I highly recommend anyone does it regardless if their original bolt meets the 1.5 to 2mm specs of clearance...they put a completely different bolt on and a huge nut from the other side...
