I've always enjoyed having a nice loud horn on my motorcycles and cars. In fact, I have air horns on my Dodge Dakota and my Ford Escort. They are useful in waking up other drivers. Whenever I add horns to a car or bike, I always leave the stock horn or horns in place. I add the extra set of air horns with the matching compressor and provide a second horn button, just above the regular one.
My rule is that I can bolt or clamp add-on items to the motorcycle, but there is to be no cutting, grinding, drilling, gluing or other disturbance to the original equipment on the bike. Sometimes you may wish to move or change items and it's not nice to leave ugly holes in the metalwork.
This particular motorcycle, the Harley-Davidson Dyna Street Bob, is rather close-coupled and doesn't have a lot of room to add things like horns. After some thought and discussion (with myself, LOL) I determined that the only possible place was on the left side, under the saddlebags.
I removed the two 3/8-16 bolts securing the left passenger footpeg bracket to the top of the swing arm and took measurements (holes on 1-1/4" centers). I then built a stainless steel crutch to mount to the two holes to hold the FIAM compressor and the two Wolo trumpets, a 10" and an 8". I think they sound a fifth note apart. They are rated at 130 db but I can't be certain. In any case, they are hellaciously loud. The crutch is TIG welded together and simply bolts on.
The horns are tucked up under the saddlebag are out of the way and won't touch on a fast corner (I've been riding motorcycles for many years and I don't do fast anymore, LOL).
I just got the horns and compressor mounted today. Still to come will be the addition of the extra horn button from my old bike and the relay. I will run 10 ga. wires from the battery and ground. The positive goes to the relay and the ground goes direct to the horn terminal. The horn button grounds the relay so that it will pull in and operate the horns. With the relay and the trumpets set very close to the compressor, the operation is instantaneous.
These are particularly useful when coming to a corner where there is a car waiting to pull out in front of you. It will definitely get their attention. If that doesn't work, I will generally apply the brakes and prepare to evade the car.
So many people nowadays are doing things that they shouldn't be while driving. They do their makeup, comb their hair, tie their ties, text their friends, talk on their cell phone and so on. I even saw a guy reading a book while driving the other day. He had it propped up on the steering wheel. I didn't get the title, but it must have been good. Reading is good for your mind but poor for your driving record.
Wolo also makes one called the "Bad Boy" which is a small combination air horn unit with two short trumpets. It's compact but not loud enough for me. Hope you like the horns. Everyone who rides a bike should have supplementary air horns.
