My little Ducati has 4 rings, with 1 below the gudgeon pin.

Thanks for the photo's Charlie.I shall be following this re-build with great interest.Were the pistons a lucky find or is there still a lot of NOS for these models in the USA?
Looking forward to the next instalment!

The ebay seller "valtermotousa" seems to have had batches of pistons made at some point or bought out someone who had. Not just for Guzzis either.

I just rebuilt a V700 drivetrain for a customer and used the same pistons. Nice quality and slightly lighter than original (490 grams vs. 500-505). A set of rings was going to cost ~ $130, so for not much more the new pistons seemed like a "no brainer".

Here's a photo album of the customer's V700 drivetrain rebuild:
