Your a wealth of information.. do you have the BIG BOOK ON H-D ?? I think thier should be a lot of old Z1s in kangroo country. Back in the day President Wilson got H-D involved in trying to catch the outlaw Villa. They sent down bikes but didnt catch him. I have a bunch of HD books, but I haven't had to refer to them yet. I moved house last week, so I don't even know where they are to be honest. In boxes somewhere Z1's are getting scarce over here, my bosses son has an orange and brown one, barely ridden since new, I think about 600 miles on it, it is beautiful.
