KZ1100A2 Tachometer Bounce

My Tachometer is bouncing starting at about 5K. It's the electronic unit on the 1982 Shaftie.

It worked fine when I got the bike at the end of last summer. Since then I've done some gauge swapping around primarily to upgrade my 85 mph speedo to a 160 mph one. In the process, I mixed and matched from about 2 1/2 sets of gauges and I'm not sure if this tach is the one that was on it or if it was from another cluster I bought.

It occurred to me to put my other US spec tach on (has the 'Headlight" indicator) on but the rubber damper (92075-1315) that goes between the gauge and the bucket is gone. The one on the bike is there but is so rotted that it is stuck to the gauge and I'll have to destroy it to get it off. I still looks OK if I don't mess with it. The Damper seems to be Unobtanium so I'm stuck with the one on the bike.

Anyone know the fix for this? My search only found a few posts that were pretty old and no solution I could find.

Anyone know where I can find a set of dampers? It would be nice to freshen up those parts even if I can correct the issue without changing the gauge.

If you find a source, please post it here, I have 2 of these bikes and wouldn't mind getting some myself.

That 92075-1315 damper seems to be a hard to find part. vintagekawasaki.com lists it as sold out.
If it's any help, the cross-reference at Partzilla indicates that damper is also used on several other models:

KZ1000-J1/J2. KZ1000-K1/K2 Ltd. KZ1000-R1 ELR. KZ1100-A1/A2 Shaft. KZ1100-D1 Spectre.

note: the 83 meters are different. the partzilla x-ref can be confusing until you get used to it.

Yea partzilla is my go to source for part numbers and oem parts.

I did the rounds to the usual suspects and found a bunch of NLA/out of stock. I found one site that I'd never heard of listing them but I'll bet they don't have them and just don't know it.

I'm thinking of making some sleeves out of delrin to slip over some silicon wrap....

For homemade, I would consider high density foam weatherstripping from the hardware store. It comes in various widths & thicknesses.

I'll consider that, at least for the short term.

I'm taking a gamble and ordered from the site that says they have them. I'll keep you posted on whether they come through.

What we need is an aftermarket company to start reproducing the NLA unobtanium rubber parts. Makes you wonder whats involved in molding rubber hmmm...

I contacted a small company that already makes some vintage UJM rubber parts about reproducing some airbox ducts, but as I expected, he said making the molds is expensive, so I guess there needs to be a definite or well-defined market for the needed part.

Had this hunt ten years ago, and stripped my replacements off a couple ebay gauges...when stuff was still somewhat available and cheap.

I think those gauge meter dampers were made from extruded foam rubber, cut to length and bonded to form the ring. You may be able to fab a make-shift set from neoprene rubber to serve the purpose until a replacement set is found.

It's official. I just got the refund and NLA message.

I was thinking of getting some delrin and turning it to a facsimile of the damper contours with just enough room to put a layer of silicon wrap under it.
