I was cleaning up today and came across the full pump recall letter I got a few months ago. Dealer told me that Piaggio sent out second wave of letters. I did not receive it during the first wave. I already took care of it for myself.
I thought I'd post this for others that haven't received it, for example if you bought a used Piaggio or Vespa and they don't know you own the bike so couldn't find you. Dealers can check your VIN to see if you're eligible or if the previous owner had done the recall already. You can also call Piaggio.
Took about an hour at San Jose Vespa. I waited for it.
