I honked at someone that merged right into me in traffic the other day and I could barely hear it through my helmet. Time to fix that.
Once the fairing was back on, it's barely noticeable.
I plugged the original horn wires right into the control side of the relay, then just added power/ground from the battery with a 15amp fuse.
I removed that ugly yellow cage and painted the disk black. Just a few hours in the garage, drilled two holes in the headlight bracket and some finessing, and voila... pretty damn loud dual horns.
