Indicators / turn signals not working?
Hello I've recently bought my first bike and it's an F3, I have had several issues with it although most seem to have been fixed. A new issue is that none of the indicators come on when I signal and neither do the the signals on the dashboard. I've check the fuse and it's fine as it also serves the horn and that's working perfectly. When I put the signals on the relay clicks at random speeds, sometimes rapid and sometimes slow. I thought that if it clicked it would send some kind of signal to either the bulbs or the dash? I'm guessing the relay is the issue but has anyone else had a similar issue where it was working fine and then all went at once? Before anyone suggests I've checked all of the bulbs
Remove flasher relay and jumper wire across terminals where relay plugs in. This will send power straight across with no flashing. So winkers should turn on fulltime when you flip switch.
if it doesn't then you may have wiring problems, or issues with switches.
Do you have multimeter and know how to use it to measure voltage? This is 5-minute fix with multimeter... or less even.
if it doesn't then you may have wiring problems, or issues with switches.

The issue was in the switch gear, a mechanic I spoke to said he's had many Honda's with this and you just need to open it up and spray WD40 in. Sure enough it worked straight away and I've had no issues since. Thanks for the suggestions.

Thanks! 
No, pull the flasher relay. It's like switch between battery and winker lights that you flip on & off to signal. Except it's done automatically. By bypassing it with jumper wire, you remove it from circuit and power makes it to bulbs directly with no interruption. Then winkers and indicator on dash will just turn ON fulltime when you flip signal switch left/right. This test shows for certain flasher relay is at fault.
However, if flasher-relay was bypassed with jumper and winkers still don't turn on, then we've got wiring problem. Need to trace power-flow from battery to winkers and measure voltage at each junction (meter set to 0-20vdc). Trace flow-path on diagram like road-map. Where power disappears shows problem is between that spot and previous test location that did have power.
