I have been communicating with
Scootworks for some time and have been waiting for confirmation that they have made a kit for our bikes. Last bit of communication stated that they have an America in the shop and are setting things up. Their price is $549 which includes the tensioner. They sell one for the Bonneville which won't fit the America/Speedy but price is supposed to be the same.
New Bonneville sells the one for the Bonney. Don't know why QPD is so much more expensive than Scootworks.
I think I'll put the conversion on hold for this year. Really don't want to wait any longer for an answer. My chain is still in good shape.
