I am in western Wisconsin during part of the summer. I have a CB350 race bike that I have been working on and racing for the past couple of years. I also raced a CB350 for several years in the early 80s, too.
Let me know if I can help you out with anything, although I won't be back to where my bikes are until the end of May or early June. I hope to go to the Ahrma race at Grattan in June and possibly the race at Beaver Run the week after that.
