Let me tell you something... Those are Nathan Air Chime horns... They do
indeed come from locomotives... However, I hope the rider wears some
serious ear plugs... Those horns, if powered properly, are too loud to be
used anywhere I can think of. We're talking levels of sound that don't just
damage but destroy ear innards, etc.

All that being said, I want 'em for my bike too!

Sweet mother of god on a paisley pogo-stick!

Methinks that there's either some "Photoshopping" going on, or the horns
are there for pure looks. How does he feed the thing with it mounted on
a motorbike?!?!?!? Train chimes (as these are properly called) take
about a bazillion CFM at 90+ PSI to operate reliably! A 5 gallon air
reservoir is, or so I'm informed by people who have tried (and given up
due to the headaches involved) to run a set on a passenger car, only
good for about half a second of "somebody stepped on an asthmatic frog"
before there's basically not enough pressure left in the tank to do more
than hiss. The pressure is easy - It's the volume they need that's the
killer.


Hmmm... MAYBE these are an electric set? If so, it'd be the first time
I've encountered electric train chimes... I can't see any signs of
plumbing hooking up to them though, and no reservoir that would even be
SORT OF close to being useful size unless it's hiding in the tail-box.

Oh, yeah, it's a set of Nathan Airchime horns, nice clean install...
But there's one huge problem with this, something you don't see in the
picture - Where in the hell is the driver of this little bike going to
get enough air to drive these monsters?

Unless he converts two cylinders of the engine to air compressors,
and has air tanks hidden in both saddlebags, the most he's going to
get out of a standard electric horn compressor is a burp out of one of
those three horns.

You want to drive that sucker, the bare minimum you need is a
modified York AC compressor driven with a starter motor like this:
http://www.onboardair.com/trailhead.htm
And you need at least 6 gallons of air tank to smooth the pulsations.

Of course, now you need 200A at 12VDC to drive the compressor, which
the average motorcycle battery isn't going to provide for more than a
few seconds, and the 30A lighting-coil alternator windings will take
forever to refill it...

(quote from m/c ng, from the person who owns the bike)
================================================== ==============
Thanks. Of course, building something like this is as much fun as using it.
I used an air compressor from an 81 Wing's suspension, 2 old propane torch
tanks as air tanks, a solonoid valve, a 140 PSI shut-off for air bag
suspension. I didn't lose any cargo capacity as it's all outside of the
bags. I get about 5 seconds continuous blast (an eternity) or about 7 short
hoots in succession, and then about 5 minutes for refill. I will be looking
to scrounge a better compressor, but don't want to use all my charging
capacity. I have an area above the center stand where i can install another
small tank, but am looking for something to fill the shape.
The system could all be removed in 20 minutes If i get tired of it (not
likely) and when I install an 81 Wing's rear swing arm and final drive on
this 76 Wing in a few weeks, I will be able to use the 81's air shock system
without the usual welding of different lower ends to the shocks. This combo
will give me a higher gear ratio for better mileage, and lengthen the
wheelbase 2.5 inches.
Tomorrow I am leaving on a ride for the weekend, so i will be able to
compare my mileage with that of my trip 2 weeks ago and see what kind of
change there is. I could follow aerodynamic practice and put a simple spike
in front of each hooter to split the airflow, but the numbers will tell me
if it's worth the effort.

Actually, not that hard at all -- get one of the small scuba tanks (they
used
to have 38 cu. ft tanks -- about the size of a fire extinguisher (some
smaller
ones also available)) and the first stage of a scuba regulator -- that drops
2250psi down to about 130 psi (you can adjust the pressure). Not good
for a lot of "honks", but should work good for some anyway.

Heh, I've got a '95 FLHTP (cop bike for th' unwashed) that gets folks
attention when I hit Mr. Horn. It's no set of Nathan's, but a 100
watt amp punchin' out a three octave siren blast wakes folks up! It
costs about a grand to install a complete Whelen system, mine was on
th' bike when I bought it.

I'd love to hear those air chimes... from a bit of a distance.

Hey... Can you tell me the model number and/or components of that system?
Whelen is one of my customers... I bet I could get those units for my local
PD at a good price.

Nuthin' to it. I don't have th' Whelen part numbers, just Harley's,
but Whelen should be able to cross reference them if theirs are
different. Keep in mind these are 1995 part #'s but just about any
H-D dealership will have a "Parts Catalog Police Models" for newer
models. I'd almost bet they're still th' same tho. That said, if
your local PD doesn't have H-D's th' mounting hardware isn't going to
be th' same as below.

Here's th' major componant #'s:

Item Harley-Davidson part #

Amplifier 91156-93
Amplifier mounting kit 91260-93
Speaker w/terminals 91157-88
Speaker Mounting kit 91154-87
Microphone 76185-93

There are two pages of other part numbers i.e., wiring harnesses,
handlebar controls, mounting hardware, etc. I'm sure Whelen has all
of that info. Last I looked it was a bit over $1k for a complete
system and that's not installed.

Disclaimer: I'm not affiliated with H-D or Whelen and th' use of
these may be illegal in many places unless you are an LEO , Ambulance,
Fire dept, or a licensed funeral escort vehicle operator.

How about a CO2 fire extinguisher bottle. Lots of volume for cheap and
all at about 130 PSI
