Clutch cable on motorcycle broken?

I wanted to ride my motorcycle again after a long break, so I recharged the battery. When I turned on the ignition, everything was normal. When I tried to start it, nothing happened. Not even a noise, just the oil light lit up. But it can't be the oil. Anyway, I pulled the clutch to try again. But then the cable leading to the lever snapped. A small, cylindrical part with a small eyelet also fell out. The motorcycle is over 25 years old, so I'd like to repair it myself. How should I go about this? Thanks in advance.
