I tried out several different models out of plastic before using this "design", this is the in my view the best compromise, as depending the mount of the speedo cable and free movement of inner wire, the laying of the electrical wires from the ignition, the clutch cable laying and the welding of the bracket for the front engine mount. Last but not least also the stability.

I tried to take away as much matrerial as possible, view of the mount/plate from bottom:

To the rubbers for the cylinder, I have the rubbers and the cylinder will get them when all other things are done.

Looks good, and well thought out.
