hey, been having that same problem. I recently bought a used 250gs and at the time it worked just fine until recently i took the carb off to have a look and when I put it back on the electric start seemed to have stopped working. It will start if i bump start it in second but when i try the electric start, all I get get is a clicking sound and it wont turn the motor over. I already changed the spark plug but that didnt change anything. what could the issue be and how do i fix it?

Thanks in advance
