Sorry for the confusion, I ended up posting this problem twice. The first thread (this) got flagged as spam because I edited it right after posting and it didn’t show up, so I reposted it. The issue has already been solved in the other thread, so this one can be ignored.
For anyone curious, the problem turned out to be the side stand wiring not making proper contact. Once I fixed that, everything worked fine. My apologies for the duplicate post!
I wasn’t able to get the blinking codes to work, but I kept digging and finally traced the problem to the kickstand wiring. The wire wasn’t always making contact, and once I tracked it down and fixed the connection the issue was resolved. But thanks anyway for the tip, I appreciate the help!
Thanks for the info! I tried it, but I can’t seem to get any blinking codes. I flipped the kill switch three times (both fast and slow), but the FI light never flashed. I also bridged the service connector under the seat, and the dash just showed “CHK” without any blink sequence, or error codes.
Could you clarify how exactly it should be done? Do I need to wait until the dash finishes its startup and shows the CHK message before flicking the kill switch, or should I be doing it during the “startup” while there is nothing on the dash?
Hi everyone,
I’m having an issue with my 2011 Hyosung GT650 EFI. The bike starts fine in neutral, but as soon as I put it in gear the fuel pump cuts out and it also disables the starter.
Here’s what I’ve tried so far:
- The kickstand switch is bypassed (wires shorted).
- The clutch switch was tested and works. To be sure, I also shorted those wires, but the problem persists.
- I traced the clutch switch wire back to the ECU and confirmed continuity.
I suspect the kickstand switch circuit. Sometimes I have to unplug and re-plug the shorted wires to get the fuel pump running again, but I don’t know why.
It feels like the ECU is still seeing an open signal somewhere, but I can’t pin it down.
Has anyone run into this issue on the GT650 or similar EFI Hyosungs? Could it be a faulty connection in the kickstand circuit, or some other safety switch? Any advice or ideas are welcome.
Thanks in advance!
