stuck gas cap 78 R100

I did not think my first request for help would be for a stuck gas cap. My new to me 1978 R100/7 motorcycles gas cap will not unscrew. It will turn counter clockwise but will only click. Any and all suggestions welcome. This was certainly anticlimactic as I was about to put some gas in to try to start to start it for the first time.
 
Thank you very much for the link. I shall attempt the removal tonight. I will be careful not to "bend the tank" as is apparently able to happen with too much force
 
:dance Very happy. The belt through the handle trick worked well. The gas cap is off so now I can do the modification/repair. Thanks again
 
Fuel cap

I had the same problem with my fuel cap on a 1978 r100rs. it was the cap with the BMW logo. Tried the belt release method but that didn't work. so decided to drill the fuel cap under the cap handle, through to the other surface inserted the end of a pop rivet into the hole engaging both drilled holes, hey presto, I was able to unscrew the fuel cap.
Many thanks to all concerned.:beer :thumb:thumb
