OK, dollars to donuts the first major issue you will have is with the carburetors, which are quite complex. There is a lot of great information out there to help you out with this, and even a great video on how to properly rebuild and set them up!
Yup, you stole that one! The sidecar alone is worth that much if not more! If you do part it out you can get $1000 to $2000 but it is a long tedious undertaking...
Welcome aboard, we will help you out with this as much as we can!
