Hi..New here. Need some information if anyone can help. My sister bought an old house recently. We were cleaning out a garage on the property and I ran across most of an old cycle frame. There was an old tag that said 1911 Indian single..I like to tinker since I retired so I figured this might be a good project. I do aluminum casting and thought it might be fun to reproduce a faux motor. The rest of the frame is no problem to make up (lots of pics and measurements online) My problem is finding dimensions for the motor. Crank case,cylinder height,etc. I've built a few bikes over the years and this just looked like a good project..Any help or a point in the right direction would be greatly appreciated..Thanks......
