Reply To: Bike has intermittent problem with shutting off when input in gear
You mean it cuts out as soon as its in gear ?
If its EFi , have you downloaded the service manual on this forum to get a flashing sequence eg. the red Fi light will blink with pauses
10 blinks, 3 blinks , 3 blinks , 7 blinks = It repeats , this is Stator Sensor Coil for example. The ECU should let you know why it didn’t want to carry on , it should report itself on the dashboard once you turn the key on, dont start it. Flick the kill switch 2-3 times quickly and wait for the ECU to flash red codes on the dash.
Report back , if you struggle to understand the sequences , record it on your phone and upload the video to GoogleDrive/DropBox etc , and get a public share link, post it here and we shall see.
Otherwise , clutch switch and sidestand switch (even if bypassed would have corroded wires inside the harness, strip back and see.) – I would NOT bypass a clutch switch though especially on EFi models.
Hyosung sold Gv250 models with carbs until 2011 in some parts of the world, Hyosung introduced EFi models in 2008 with a SENTEC ECU (ultra rare now) and sold them until 2009 , then 2009 was the start of 2nd generation EFi which had Daewoo ECU until 2012 (then it is now Delphi ECU present day)
So being a 2009 of yours , I don’t know what’s under your hood (carbs? EFi? – Though EFi manual is at the forum to get error codes , if its carb model then it has way less electronics to diagnose)
