I'm try to do my own dual sport kit. I got everything I need for my state except a horn kit. I tried the one from four strokes only but it doesn't work well enough...Can't hear it over the exhaust. So has anybody put together their own kit for a wr426? I need a horn that will work with alternating current...b/c I don't want a battery. Any suggestions on how to do this or info on where to get one would be greatly appreciated. I've search but cant find anything.
