Yeah Dennis, been having great weather actually, makes me very suspicious, hehe. I've been commuting nearly everyday now for about three weeks. Actually though I ride every chance I get, no snow and at least 20 out and I'm on it.
As far as I know Frank makes these pipes in small runs and when they get enough made put them on Ebay. An email I had a few weeks back stated he was in the process of making more but was also making some for a bunch of Guzzi guys that had inquired about them. You may just want to email him direct. Just make sure he understands they are for an 1 3/4" header as his "standard" pipes fit 1.5's
