I mounted air horns on my 1500 but I need info on mounting them on the 1800. Have any of you done this.......any problems during mounting....how long to mount.....Should I let a dealer mount them?? Is there an electric horn that is as loud as the Rivco horns? I have not purchased the horns yet and may not get them at all if there are major mounting problems with fairing etc. . Thanks for any information this board can give me.
