The sprocket recall is a visual inspection in the first instance - purely to determine and confirm exactly which sprocket has been fitted to the machine.
If it is the first specification it will be changed to an updated version.
You will not be able to tell be looking - your sprocket will look perfect.
The simple answer is not to worry, take it to your local dealer that WILL be able to tell by looking.
They will replace your sprocket free of charge - usually while you wait.
