    Last couple of days have found that the indicators don't always work as I am riding along. Everything works when I start off but after a mile or two if I press the indicator button to the right either nothing happens or the indicator light on the clock flashes once then nothing. I have sprayed inside the control box with GT85 and wiggled the button. Tried tugging on the wires from the indicators to detect a intermittent circuit but to no avail. Any ideas anyone, a new switch box is over £200 and I don't want to buy one if that is not the cause.

    Does the left indicator work OK?

    not sure if the problem starts with the left as it does with the right but either way once it refuses to work neither left or right works until it decides to.

    If both indicators are dodgy it might be worth checking the relay which should be located under the seat or side panels? There will be a number of relays and you need to try and identify which one is for the indicators. I take it the indicators are original and led?

    yes they are the originals, I looked at the Haynes manual and it doesn't seem to list the indicators as on a relay that I can see but I will check tomorrow thanks.

    If there is no relay it seems that the indicators will be controlled by the ECU with a flasher unit built into the instrument panel? Have you tried altering the indicator settings in the bikes menu? Are the indicators set to self cancelling?
