I removed the tachometer so I could paint the gauge plate. Now, the tachometer is very slow to respond. It's like the needle is moving through molassas. I checked and the cable is secure.

Any ideas what's causing this?

whens the last time it was lubed?

Not sure. not in the 8 months i've owned the bike.  It was working fine until I removed the tachometer to repaint the gauge panel.

Is it screwed back in all the way?

Yeah.  It's as tight as it will go.  It still "works"... you just get no immediate feedback.  You can crank the throttle back to what should be about 5k RPMs but it'll make its way to about 2k after about 2 seconds.

It also does the same thing when you release the throttle.  Instead of shooting back down to 1.5kRPM, it just extremly slowly moves down from wherever it was at.

did you get it lined up right when you put it back in?  im sure it has a square end that fits into the tach to run it like a speedo would right

This is what mine is doing after removing the gauges and changing all of my bulbs.  What wound up being the problem?

Check that the cable isn't kinked anywhere. And I don't know about the GS cables, but I've seen cables have a loose fitting on one end. Not common but possible.

I had this problem when I removed mine to replace the bulbs with LEDs. I discovered that the part of the cable that spins was slipping inside the receiver on the tach. I took everything apart and it looked like the spinning part of the cable and the receiver hole used to be square shaped, and are now rounded. Removing the cable broke whatever connection they had and caused everything to slip.

In troubleshooting, I varied the RPM with the tach cable disconnected and noticed that the spinning part of the cable was responding properly. I'd try this to verify it is the same problem.

I fixed it by putting a drop of nearly dry epoxy on the spinning part of the cable, then inserting it into the gauge and letting it dry for a few days. I haven't tried taking the tach cable back out, so I'm not saying that it is a perfect solution, but my tach responds normally now .
