I've had mine on for a couple of months......Moves the "cages"
right over when they try to intrude on my "space"....
I didn't use a relay, I ran wiring from the airhorn over to the original wiring, removed the stock horn and connected the wires....Instant LOUD
The idea of drilling the fairing was unacceptable. I "diddled" around awhile making some tasty little aluminum brackets that ran from the blinker mount post and from the fairing mount tubes and like that. In every case, (because of the single screw mount)
the horn ended up being just far enough away from the fairing to interfer with the fork "right/left" movement. It wasn't snug up against the fairing. If I mounted the horn with the compressor up and horn(s) down it also interferred with the forks because of the mounting bolt.
My solution was (with no mounting screw on the horn)
to find the low spot in the fairing (kinda of a VEE where the two pieces are joined)
that allowed the horn to sit and not obstruct the steering function in any way.
I did trim the entire length of the horn snout where it touched the fairing (about 1/16th")
so that the horn sat truly vertical.
Once I found the "perfect location" I marked the appropriate positions on the horn and the fairing (places where they touched each other)
and applied some serious industrial strength VELCRO (3M Dual Lock)
I had left over from my boating days. (Not the cheap store stickyback stuff)
The Griot horn doesn't weigh very much so with three different velcro attach points "that puppy ain't moving"
. In fact when I went to take it out to connect the wiring it took two hands to wrestle it free from the mounting position.
I have used industrial strength Velcro (3M Dual Lock)
on a variety of applications on my vehicles and my Catamaran and never had a failure.
Thought I might have a problem with the horn sucking rain with the horn up, but so far it hasn't been a problem even in really heavy rain.
