The older tank mount is rubberised, the tube through the frame is on a rubber mount but if you over tightened the bolt you can crush the thin walled tube and this makes vibration worse. If re-fitting the tank, check it is level. Whether you have lugs or not there will be a happy point on bolt torque for least vibration. If the tank rear/head stay comes looses, and it can, you get a lot of vibration. If you start getting a lot of vibration, check head stay, tank mounts and front engine mounts, also head to exhaust ring bolts.
The bike will vibrate a lot when new and loosen every nut and bolt it can, the vibration is telling you to keep the speed down and run it in. The book says 35-40mph but is too slow for top gear and it will knock-bottom, 45mph gradually going to 50mph as you get a few miles on it. You should be able to feel the engine and gradually increase the work going into it as it loosens up. I think most riders can feel when an engine is happy and when it is straining. Don't strain it.
