1974 Eldos with the disc brake have a cartrige system like
the T series.

Does this mean that later Eldo's had some other type of
damping system
in the forks? I thought all loop forks were the same?
If not, that
explains why Cam's 74 Eldo seemed so much better up front
than my 71
Ambo.

 Bob,
I have heard clunking on two Eldos. A '72 that we
never figured out
but thinking back it may have been in the forks. That
one had a Wixom
fairing with a radio and speakers mounted in it. A lot
of extra weight
on
the front. Thinking back it may have been in the forks,
I don't recall
any
cracks in the fender when we had it off. The second was
my current
Eldo, a
'74 with a disc and a Wixom fairing. It turned out to be
a slightly
loose
bracket on the fairing that chattered when a bump was
hit. The chatter
was
amplified by the fairing and really sounded bad.
I have had three Eldos and Ambos and worked on
several others and
have never seen a cracked fender except for the bracket
on one I saw in
a
picture and that was a '74 with a disc. If there are
cracks in the
fender
the would most likely be in the brackets that hooks to
the fork with two
bolts on each side. If so the bracket would fall off
when the fender was
removed. If the fender is properly installed then there
is very little
stress if any on the sheet metal. However the fender can
be installed
wrong.
A shop in Virginia put mine on crooked once, two bolts
properly on one
side
and only one bolt engaged on the other side. Found out
as soon as I got
home
and saw the paint scraped off one side of the fender
from hitting the
fork
covers. I corrected the problem before any cracks had a
chance.
If the fender is OK and all the bolts are
correctly installed and
properly tightened then I doubt that the fender is the
problem. If you
have
a fairing or windshield make sure that all the mounts
and brackets are
tight. Also check for tight triple clamp bolts and any
thing that is
mounted
to the front of the bike is tight. The fender is rather
heavy and
removing
it could lighten the unsprung weight in the front enough
to cause the
noise
to disappear with out actually causing the noise. I
don't recall the
year of
your bike but the earlier Eldos and Ambos relied on the
weight of the
oil in
the fork to provide what little damping is available. If
you fork oil is
to
light it could aggravate the problem. If all else fails
I guess you are
down
to pulling the forks and checking them. A broken or weak
spring can make
noise as well.
The Key is to check the easiest to repair things
first and then move
on to the harder things. That way you don't have the
forks rebuilt only
to
find a loose bolt while reinstalling the forks.

P.S. How much do you have to get for your fairing and
are the mounts
with
it?

 Alan,
When I take my fender off the front the noise stops.
One guy here
mentioned
 it may be a crack in the sheet metal. I never would
have thought of
 that.

<<<<Now I have a clunking sound.>>>

Once upon a time (about 12 years back) my then new
to me 69 Ambo
developed
 a
 clunking sound in the front end. After much
deliberation I pulled the
 forks
 off and found that the left fork rattled when
shaken. With GREAT
 difficulty
 I pulled apart the fork to find that the "follower"
had unscrewed from
the
 
 bottom of the damping rod and was bouncing around in
the bottom of the
 fork!
 I have been told this is very unusual. Hope your
solution is easier.
