With in the first 100 miles on my ‘14 GT from buying it new at the dealer, I made two custom horn brackets that mounted in the stock location. The brackets were not as tall as the stock brackets which lowered the horns about 2 inches. Not much but did look better. About a year later, one of the custom brackets cracked and broke. I ended up removing both horns. I mounted the higher tone horn under the tank. I believe the fuel pump is mounted to the frame directly under the tank with a 10mm bolt. I mounted the higher tone horn to that same 10 mm bolt and used a couple dabs of blue locktite so the bolt will stay tight.
With out looking at my maintenance record note book, Id have to guess that I mounted the horn under the tank between 1,000 - 2,000 miles on the bike. I now have right around 13,300 miles on the bike.
Mounting the horn under the tank gives the GT a much nicer and cleaner look then having both horns directly in front of the engine. Iv had no issues with the horn mounted under the tank. The higher tone horn cuts through traffic noise better then the lower tone horn.
It took about 30 minutes to remount the horn under the tank, and re route the horn wire so that the wiring looks stock and not an eye sore. The second horn wire not being used, I put some electrode grease in the connection to keep moisture out and so the brass connector ends wont Corrode. Then I too about a 5 inch length of black heat shrink tubing and fitted it over the plug end. Heated the shrink tubing so that it would seal around the plug. I made sure to leave a couple of inches of heat shrink tubing past the end of the plug so that way it the heat shrink tubing would shrink up against its self and seal the end of the tubing so no moisture would get past it. Cut the Excess tubing from the end of the plug, being sure to leave about 1 1/4 - 1 1/2” of the heat shrinked tubing as a little big tail. With a mechanics razor blade, you can easily cut the heat shrink tubing off of the plug if you decide in the future you want to use it again.
I dont ride in the rain and my ‘14 GT has never been caught out in the rain, but living here in Houston with our 9 months of crazy 80% +++ humidity, its still very important to protect wire connectors and relays with the proper electrode grease / gel to prevent the connector from corroding.
Living here in Houston Tx where since the last week of May this year we’ve only had about 5 or 6 days below 99° F. I never liked the stock location of the horns because it didnt look good. I also didnt like them being mounted directly in front of the engine where was the opportunity for them to block some air flow to the front of the engine. I dont know fir sure if they actually do block the air flow or if there noting to worry about. The way I think about it, Its like a penny, have enough pennies and you end up with a dollar. A small fraction of blocked air flow here and a small fraction of blocked air flow there, pretty soon it all adds up to a decent amount of air flow blockage. Any time you can allow the engine to get a free flow of air helps.
Me personally, I wouldnt want anything allowing for the chance of goofing up the air flow to the engine. Might be worth a try mounting one of the horns under the tank. If nothing else, you dont have an ugly horn visible for everyone to see.
