Hey all,
This is the second season with my bike and I have found an intermittent problem that has seemed to gotten worse. My bike is mostly to work and back daytime riding, but last night was my first out of town jaunt. My son and I were playing leap frog through town, so he saw me at all angles as it was getting dark. When I pulled in behind him at home right at dusk, my headlight was off and my instrument panel backlight was off. My son also reported on the highway that my tail light was going on and off. I noticed reflective signs were also bouncing light back in the same oscillating fashion riding normal speeds through town.
I shut down with the kill switch, but when I flipped back to on (not start), everything came to full brightness. I hit the starter and it took a little too long (in my opinion) for the lights to come back. Just siting in place for a few minutes running, no issues. Engine revving caused the standard light brightness increase, and back off slightly when back to idle. Sitting in place and trying to shake the crap out of the running or off (but lights on) bike does nothing to repeat the issue. Starts strong every time! The phenomenon only starts to happen during riding.
Any way, long winded story. Where do I start to look on this? I consider it a safety issue and will not ride it that way.
