Driving down motorway today, headlights on, put on indicator and speedo needle dropped in speed from say 70 to 20mph and instantly recovered. It seemed to happen when I switched on indicators. Didn't happen if headlights turned off.
On holiday and few tools where I am. Any suggestions, loose connector to flasher relay? Bad earth, loose battery connection? Bike had done 300 miles of journey before this happened, will try to replicate if I can tomorrow. Will check the battery connections and indicator connections first.
Thanks
Gordon
