Reply To: Hyosung GT125 turns off while running
It’s really difficult to diagnose a fault like this without being there in person, it’s not mechanical so my hunch is it’s going to earth somewhere, it will be a process of elimination remove the headlight easy to do & very carefully check all the wiring coming into the headlight shell & where the wiring loom passes the head stock look for any damage no matter how small & unplug all the connectors 1 at a time spray with contact cleaner & reconnect try that 1st.
