Theresa's instruments were submerged in 2013 along with the rest of the bike. The speedometer seems functional -- the odometer anyway, I can't be sure about the accuracy of the needle. But the tach just didn't want to get off the resting post, and when it did it got stuck at 3000 rpm.
So I took it apart. Still harboring dried mud.

The reason the needle was stuck was this tiny washer on the needle axis. It seems to be made of fiber and may have swelled up with moisture and never recovered its original ID. I tossed it out.

Back together, the tach works but the needle bounces around fiercely. That washer is apparently a damper.
New Vega tach on order.

The Colorado climate should dry out anything. The counterweight is still on?

What bike is this for?
I have two tachs that might be of interest: (1) one from a EV/Jackal seriew with less than 1500 miles, needle barely sunbleached, about as close to NOS as you'll find. I don't know that it works, but I'd expect so and (2) one from a 2000 Bassa with 80K+ miles--the needle is painted black. It is accurate but sits at about 1K with the ignition off.
Make an offer if interested.

Another option to consider is Speedhut. They make some sweet electronic tachs, and can be gotten with Guzzi logos. I have one on my cal II, and am very happy with it.
