Axle,
Just caught this thread and wanted first to welcome you to the forum and second, to compliment you on your build. I love the 'machine' look it has and while not usually a fan of mag wheels, somehow they look good on your build. I have a build going on right now (Indian Hiawatha) using a model 1932 Fitchel Sachs 2 speed 98 CC 2 stroke and am much impressed with its old school German engineering. I have yet to fire it up, but know it is going to be a great power plant. Your bike reminds me of some of the wonderful light motorcycles produced in Germany years ago. If you have them, please share some photos of the gas tank coming together and some commentary on how your made it... real nice!
