Hey there w8n4myruca.
Have you installed LED indicators onto non LED fittings, with the resistors in line?
I've had the same problem on my ZX6R, and it seemed to all come back to the resistors playing games with the very sensitive wiring in my standard flasher can. The standard parts don't like too much change in voltage, and can start doing weird things when you change line resistance.
The buzzing noise could be your flasher can buzzing as it tries to blink but gets confuzzled by the weird voltages.
To resolve the problem, I found an LED specific flasher relay, that is designed to work with lower voltages in LED lighting. You can often find them on eBay, or from after market parts dealers and bike shops that are a direct fit to your standard wiring and relatively cheap too.
Try typing "kawasaki LED flasher" into eBay and see what comes up.
Hope that helps!
