My thinking is that a bit of flexing via the "leaf spring" type brackets
may prevent my little alum. angle brackets from cracking. Kept the holes
very close together (so close in fact one bolt head had to be ground
nearly to half size to clear the other) in an effort to keep any stress
centered in the "beefiest" area of the alum. angle. If they fail, I'll
remake them in stainless. Sophia (even with one injured cylinder) was
lots smoother than the '69 for some reason. From time to time I would
watch and lightly touch the horns to try and get an idea of how much
they vibrate and they don't seem to very much. The Hellas are pretty
heavy which might help dampen the vibes some also. Time will tell...

The Fiamms came with some longer chromed steel brackets. But, they were
a little too long for what I wanted and were a little flimsy. The
brackets I'm making now will be painted mild steel. Charlie, I think
you'll be in much better shape with the angle "iron".

Hi Greg,

My brackets are aluminum, but are only approx. 1" square. I've been
kinda' checking them after each ride for just the reason you mention.
Been carrying a pair of vinyl-covered metal clamps to fit around the
crashbars in an emergency if they do fail. My Hellas came with the usual


multiple layer "leaf-spring" brackets, these bolt up to my homemade jobs


- did the Fiamms come with them? I've seen the "snail type" horns in
that location with the leaf-spring mounts without problems. Cheers,

FYI: I purchased a pair of high and low tone FIAMM horns (the kind that
look like a snail). I made a simple straight bracket about 2 1/2" long
out of 1" wide aluminum (1/8" thick) so that I could mount them just
below the top crash front crash bar mount using the standard 8mm bolt.
The engine vibration was too much for the aluminum and one of my
brackets broke in half right where the bolt went through it. Looks like
I'll need to use regular mild steel or stainless.

Charlie, did you use stainless for your brackets on Sophia?
