Speedo and tach issues

Post by brecchi » Tue Oct 24, 2017 11:50 pm



Hello, I'm currently on a shakedown trip from DC, currently in Houston. Bike is an 81 GL1100 with 15,000 miles, in great shape and well maintained by the PO.

2 days, I noticed the tach gauge needle bouncing around for a while ,and then it just stopped working altogether. The next day, the speedometer started doing the same thing, bouncing around a bit between +/- 5mph of actual speed. The odometer was working normally. There was a bit of a screeching sound from the gears when taking off in first an then the needle actually just fell off! Its now laying sadly at the bottom of the dial. At around the same time, the odometer and trip odometer both stopped working and it seems that the light output at the bottom of the speedo is out or something p its very dark towards the bottom half.

The fuel and temp gauges are working fine.

Any guesses as to whether its bad cables, gears, etc?

Thanks,
Ben

I would think from your symptoms described you will need to invest in two new cables - the cables do need some lubrication - so not strange to hear that screeching sound is where it becomes bound up and eventually snaps somewhere along its length.

Pretty easy to confirm - just remove the cable from the back of the dashboard then pull the inner cable - see how much you have left.

One other possibility for the speedo is the actual drive itself has disintegrated internally, but first checks should be your cables.

Thanks - any idea of the best way to get to, and repair the speedo needle which fell off inside the housing?

You would need to disassemble the speedo itself - I've never done that - it depends on if you can separate the speedo casing, if so you should be able to reattach the needle..

Look on the internet for a possible solution - and also I would be looking for possible a replacement speedo.

cheers

Upon closer inspection, it looks like there isn't a problem with the speedo light, its more like a fine black powder is coating the lower half of the gauge and obscuring the dials (which aren't turning anyway.) Bummer.

Okay - so the tach was nothing more than a cable which wasn't fully inserted. I had to rush out of town but when I get back Ill start by pulling the speedo cable off. Either way though, Im anticipating a pretty involved fix as far as he needle and fine black powder coating the inside. At least if the cable is bad as well, that will take care of the odometer. Thanks for the insight - I may need a walkthrough at some point on taking the housing apart.
