Gauge grease

Greg (Don)...
      Where'd you end up finding that gauge grease?.
My gas gauge at 44k miles has started the bounce...  Needle flipping all over, but not all the time..

Bruce,

For others looking for this in the future, the thread is here with the specifics of the thickness I bought.

I bought it on eBay. I found it under silicone damping fluid. It’s used for a lot of things.

With all that said, the weight I bought may have been too thick or maybe I need to take the gauge apart to get it in there. I removed the fuel gauge and wiped some of the fluid on the gauge shaft using a toothpick. My hope was that gravity / capillary action would draw the fluid down into the bearing.

Well after a few weeks it hadn’t done a thing to fix the wagging. I removed it again and buttered it up. It’s still sitting on my dining room table and I don’t know if it’s worked or not. It’s been six months...

So if I were going to buy again, I might choose a lower viscosity. Or maybe this will take more invasive disassembly. No definitive answers right now. Sorry. I’m not desperate enough to try to remove the needle yet.

Update to the previous post:

Plugged the gauges in, rocked the bike. The fluid didn’t wick down into the bearing as hoped. I guess I’m going to have to figure out another method to get the fluid into the bearing.
