I had a similar problem. Solution: install an electric flasher bought at Pep Boys Auto. I then cut and capped the wire leading to the dash signal indicator light. Fast/weird blink solved.
I am revisiting this issue... Can you tell me what wire leads to the Dash Indicator Light? Also, is there proper way to remove the Dash Panel? I still have the factory windscreen on the bike.
To recap: I ordered an LED Blinker switch and installed it along with 4 LED blinkers. When I operate the signals, all 4 blink nice and steady like hazard lights.
Thanks
