Speedometer Needle Broke Off

[OPTheory]

The speedometer needle was bouncing all over the place the past few days and had been in need of a lube - I thought I would do that tonight.  Well I was riding home tonight, going along at about 50 or so, I look down on my speed and all I see is a stub where the needle used to be.  I have no idea what happened, maybe it just bounced too hard and it happened to break off?  I have no idea. 

Now my question is, does anyone know of an alternative needle that I can simply put back into place?  Honestly, i don't want to fork out the money for a new tach/speedo gauge just because a needle broke off...

Any help would be greatly appreciated!

maybe open up the speedo and use some handy super glue skills

[OPTheory]

Yeah about that, I don't know where the broken piece went...

This sucks.

Have a look for Kerry's discussion on removing the gauge bezel by filing off the crimp on his webpage. 

Kerry also talks about removing and reinstalling the needle.

I've been into several speedometers and tachometers. The needle can be reinstalled.
(Is is still inside the glass isn't it?)

Getting access is the hard part. I made a motorized jig to spin the entire speedo around while I held a file against the crimped edge.

Reassembly is with black RTV Silicone.

Here's some shots of the process:

Well guys, I looked in a bit deeper and I guess the piece still is in there.  Gluing it on probably wouldn't be the best option.  Currently the speedo is pointing to 100 mph but moves very slightly if the motorcycle is ridden.  I confirmed that the cable is fine and the problem is within the speedometer box.  I'll have to take a look in it tonight.

So how do I actually get inside this and has anyone had a problem like mine?

Thanks!

Forgive my ignorance, but I can't seem to find this anywhere on his webpage.

I don't remember a Kerry thread about this. That may be why you cannot find it.

You must remove the metal bezel that forms a sandwhich around the front of the case.

Is your bezel black or chrome?
Regardless of the color, you have to remove the bezel.

You have two choices:
1) Pry the back edges sufficiently to get the bezel off.
2) Cut the folded part that makes the back edge - as in my photos - to get the bezel off.

A third choice is getting another speedometer and sending the bad one to me. If I had a spare speedo, I would trade for shipping costs.

My second photo above shows the results of disassembled "clocks" (Brit. slang - cool isn't it?)

If you are really in a bad way and not riding, you could send the thing to me and I will open it for you. I offer no guarantee that it will get repaired, but it will get opened.

Could you be referring to the old GSTwin.com page about LEDs?

Ooops!  My mistake!  It was Starwalt that was doing the gauge bezel removal.

[Kerry]

Yep, definitely starwalt.  I've never opened up my gauges, but I'll be checking out HIS posts if I ever need to.

I've got a spare I could send for the cost of shipping.  However, I'd have to check if it's in decent shape.
