Finally I made it.
She is on the road since January. What at first appears as a 1960 SR, is now except of the front end a 1954 GF. I made one bike out of two, used the parts which are in the best condition. I did a thousend miles since and she runs perfect, the rings are betted in and all the electrics is working.
I would not have been able to manage the restauration without the great help of you forum members, and I want to thank you very much for this.
Stay safe, Hans.
