Speedo restoration

I am a huge fan of the unmolested speedo on a fully restored bike. I purposedly left a couple "aged" items on the bike to show its history, and the speedo is the most noticable one.

I have a Rally 180 (VSD) style headset, which was produced on the latter USA released SS180s.

In the slideshow above I show you how to replace a broken face plate and seal your speedo up again.

Here's what you need to do:

1) Purchase a new bezel and face plate.  I purchased NOS from Scooter Shop.

2) The bezel is folded over the back of the speedo.  It seals it very well and compresses the gasket inside.  Without a doubt, the internals of the speedo were spotless and the cleanest part on my bike.

3) I used a tiny flat head screw driver to elevate the locking lip of the bezel.  If I had to reuse my original bezel this would have been a major pain in the butt, because the bezel was misshaped afterwards.

4) With the small screw driver break apart the old black gasket between the face place and metal speedo.

5) Now release the plate.

6) Clean ONLY the external and the area where the new seal will go. Use a mildly abrasive pad without chemicals.

7) Put a new seal on.

8) Clean and then put on the new face plate.

9) I chose not to fold over the brand new bezel, because I was scared I could damage it.  Instead I used a "gasket maker silicone" and sprayed it around the seal.  I then pressed the bezel back down over the top of it and put a heavy weight on it to compress it.  It sat for 24 hours.

10) Finally, I used the gasket maker again and sealed the gap between the lip of the bezel and the speedo itself.  Don't stress . . . you can wipe the silicone off with your thumb AFTER it dries for clean up. Let it dry - don't mess with it wet.

Remember that this is all facing downward, so if it rains or the bike gets washed I am more than safe since the bezel is filled with silicone.

If you would like a SPECIFIC picture from the slide show posted so you can view it as high resolution and HUGE on your screen, please leave me a comment and I will post it.
