First I'm not sure how to remove the gas tank on my 1976 honda supersport CD750F. Can anyone help me out with that?
Also, the motorcycle starts when I jump start it but as soon as I stop giving it gas with the throttle it stalls. It won't start when I push the electric starter even though the battery is fully charged, and it was suggested that it is a faulty relay switch. Where would I locate the relay switch and what should I do? Does it need to be replaced or...?
Help!

Thanks,
J
