I'm looking for a copy of the May 1971 issue of Popular Cycling. It features an article on a Cheney Yamaha similar to mine and I need everything I can find on this bike before I undertake the resto. I'm also looking for any magazine articles on Cheney 2 stroke and XL Honda powered machines and anything at all on Boyd and Stellings frames, swingarms or whatever and anything to do with Hindall frames. Of course if you don't want to part with the magazines (and I wouldn't blame you) I'd be happy with scans or photo copies.
