Check your starter switch. The starter switch has additional contacts that control your headlight relays, so when cranking headlights are OFF. Sometimes the switch can become sticky and doesn't fully return to remake those contacts meaning no headlights. With ignition to off give the starter switch a squirt of WD40, exercise the switch and see how that goes. Link to comment Share on other sites More sharing options...

Then it's looking like the Starter Switch issue. What you've explained is exactly what will happen if the Starter Switch is NOT making the lighting contacts when released. A good way to exercise the Starter Switch once you've given it a squirt of WD40 is to set your red KILL SWITCH to the OFF position. Then, with Ignition to ON you can activate the Starter Switch (engine won't crank) numerous times and observe your headlights, they should be ON until you press the Starter Switch then they should be OFF. Lets know how you go. Link to comment Share on other sites More sharing options...

I know of at least two VFR's including my own 2009 that lubing the switch did fix the issue. You now need to check the Starter Switch for continuity and its wiring. Do you have a multimeter and know how to use it? Do you have a wiring diagram of your bike? Attached is the area you are going to need to check. You need to know when NOT pressing the Starter Switch you should have continuity between the Brown/Blue wire and the Blue/White wires. Then you also need to verify you have 12v at the Brown/Blue wire with Ignition to ON. You will probably need to locate the RED 9P connector down from the switch assembly to do these checks.

Well it ended up being the switch I made a simple bypass and it works perfectly Thank you in advance mate Link to comment Share on other sites More sharing options...
