Hi! I'm new here, obviously, and still own my first bike, which is a 69 sand cast, serial # 827 and decided I'd sell it, but ebay people picked it apart so bad that I decided to just keep it. It's about 90% original, and doesn't have a wrinkle tank anymore as I did a restoration on it years ago, and didn't know about wrinkle tanks, and replaced it with a NOS. It runs great and besides the wrinkle tank thing, it's all there. If anybody has one of these tanks, or knows where I can get one, give me a shout. I don't think its all that important, but I know the anal restoration crowd demands 100%.
