been noticing after about ten miles,, radio picks up engine noise.. just tried radio and bike was on the trickle charger and that was mess'n it up.. I don't think I just need resister plugs,, think sumthn's goin out in the radio.. last "attempt" at getting the cassette player to work,,, when I put the cassette in the fairing,,,,it had a profound effect on the radio,, it's supposed to switch it over to cassette,, but more like I was wreck'n sumthn internal in the radio when I was trying it. do I need a different radio? or could this one be fixed?
