The first basic is, the Guzzi drum forks have no dampers. For all
practical purposes, they're just a set of springs holding the sliders
from bottoming on the tubes, kinda like old shocks that have lost most
of their oil.

Heavy oil in the forks adds some drag that mimics damping, and the
forcing cone at the bottom also is a crude form of damping. That's the
best you can do on these forks without adding some form of damping rods.

I'm working on a way to fit FAC sealed dampers inside. I'll have to
make some tooling and use it to modify each slider. I want to do this
on my V7 and A-series Ambo, but if others are interested, it might
prompt me to devote more time to the effort.

I shipped a bunch of alternator kits yesterday. Some of you will see
them soon.

Okay, education time for me. Can you explain the differences - or at
least point me to a good resource to read - about spring, dampers, etc?

Since you fellers are putting so much time into improving your forks,
meebe you'd be interested in really improving them.

I'm working on a way to fit dampers to Loop drum forks. Might some of
you also be interested?

Hi Ray,

Just the springs, no spacers.

Greg,
I also installed the Wirths on my Eldo but have yet to ride it, so
no
impressions. Did you use a preload piece as well or just the
springs?

Last weekend I installed new Wirth fork springs and a new set of
the
13.25" Ikon shocks (thanks, MG Cycle). Wow, what a difference! The
bike
handles much better with slightly quicker steering and I really
appreciate the additional ground clearance (which I even found
forgiving


of the Dunstalls replicas mounted wide and low when I didn't choose
the
best line through some curves). I'm no suspension expert by any
stretch
of the imagination, but I'm very happy with my upgrades.
Originally,
I
had the stock fork springs and a very cheap set of 12.5" shocks on
the
rear (less than $50). Why didn't I make this upgrade long before
now?!?
Now, I just need to find a completely free Saturday that I can go
ride
around and play with all the settings on the Ikon shocks. :>
