Direct Replacement
-- porkchop -
I added a Fiaam electric horn as a direct replacement. Available for
around $10 from your local auto store or JC Whitney. At least as loud as
the loudest car electric horn,
-- t bone (tbone_spirit) --
mounted a $35.00 jc whipme oogah horn on an L bracket from a bolt on my
crash bars at the top, used the regular horn wires, loud as hell and
everyone looks wondering where the model T with drag pipes is LOL

Are you tired of the feeble sounding stock horn that has been supplied by
Yamaha? With very little effort you can replace it with a 120 decibel Fiamme
“Highway Blaster” electric horn. The benefit here is that you can, with care
and attention, mount it in the stock horn location. Mine lived there for a
few years until I mounted it in an unused air cleaner housing. Take care not
to let the body of the horn extend more then one inch to the front of the
frame tubes in that location. This will still clear the fender on a fully
compressed fork by about 1”.
I found mine at an auto parts store, but they sell the things all over the
planet. Just make sure you get the “Highway Blaster” not the Fiamme
“Blaster” model which is not as loud.
Because of the substantial current
draw of this monster, you will need to wire a relay with direct fused power
from the battery to power it up. Although they don’t list the power draw of
the Highway Blaster, I can tell you that it will fry a 10 amp fuse, and I
had to go to a 15 amp version to make it happy. Pick up a plastic body,
generic 30 amp relay at any auto supply store. The stock Yammie Horn plug
wires will both power and supply a ground for the relay. Polarity is not
important so it does not mater which wire goes to each or the two switch
controller posts. Use crimp-on spade connectors for the wire ends. (See
relay wiring diagram, discussion)
Most auto supply stores sell in-line automotive style fuse holders. Run a
hot (fused) wire to one of the switched posts on the relay, then run a power
wire from the second switched post on the relay to the horn. Run a ground
wire from the second connector post on the horn to ground. If you blow the
power fuse when you blow the horn, just reverse the power and ground wires
on the horn and you will be good to go. Fiamme of course does not give you
any indication regarding which is the input post and which is the ground.
When you are done, I would recommend that you completely seal all of the
openings in the bottom of the relay housing with either GE Silicone seal or
something similar. Plastic tie all of the wiring to the frame under your
tank and you are done.
Now when you press that horn button, you will activate the magnetic switch
inside the relay. That will send power to that “WAKE UP and WATCH WHAT YOUR
DOING” monster horn that you have. This horn has already caused individuals
to jump when they were standing near the bike and I hit the horn button.
If you choose to relocate the horn to another location, it is a simple
matter of just extending the wiring to wherever you decide to put it.
I remounted mine “sort of”
inside my old Baron’s BAK filter housing which still lives on the right side
of the bike (after MaxAir). If you will refer to the attached photos you
will see the 2.75” hole that I cut in the aluminum backing plate. I then
used an epoxy adhesive to mount the circular portion of the horn body into
the filter backing plate. When the epoxy had set up, I replaced the teardrop
K&N filter and then screwed on the chrome face plate for a perfect fit.
Positioned where it is, it projects most of it’s sound to the front and
right side of the bike (right at the driver’s window of an offending cage
who is about to enter my lane and try to kill me).

Another way -

And yet another - in the Dog
Bowl - Dipstick - (pictures coming) -
I installed mine in my
unused dog bowl. It was a tight fit but it worked out great. Once the
chrome cover is installed, it does muffle the sound slightly. But still
load enough to wake any cager. This is the Wolo horn from Harbor Freight
for $44.95.
