Topic: Tach/Speedo lenses?

I'm confused about your statement:

"I removed the entire unit from the chrome ring that holds it in place and then I very gently pulled the plastic housing off. I was suprised how easily it came apart. It appears that the only thing that really holds it together is friction and the chrome band which holds it on the bike."

I took my tach off the bike last night, and the bottom of it had the black plastic housing wrapping around the bottom by 1/2 inch or so. I don't see how the metal portion could be pulled out without removing this lip around the bottom. Maybe yours has been previously disassembled? This must be clear as mud...

Are you talking about the 1/2" rubber strip that wraps around the bottom of the tach body and sits between the chrome ring and the tach body? If so, this ring simply slid off my tach. Mine may have been apart before, it didn't look like it but I don't have anything to compare it to. At first I was quite mystified how I was going to get the thing apart because I couldn't find an expanation anywhere. Mine didn't seem to be sealed at the bottom, if that makes any sense, so out of desperation I simply tried pulling the body off, and lo and behold off it came much to my suprise. I don't know if that makes any sense or if your is somehow different than mine. I'd be interested to hear if yours is some how sealed at the bottom.

Yes, mine is sealed at the bottom. The plastic housing wraps around the bottom outside of the metal instrument housing by 1/2 inch or so. It looks like I'd have to trim it off to pull the metal housing out of the plastic housing.

Hey 750k4,

You don't happen to have a digital camera do you? I'd love to see how its supossed to look. Mine has obviously been apart before, whoever did it did a great job beacuse I can't see any evidence that its been cut. No wonder it pulls apart so easily.

I think I can scare up a pic. I'm out of town for the weekend - I'll snap one early next week.

It's been raining quite a bit, and I haven't made it down to the salvage yard.

In case you didn't look at it, here's a link David left this morning.  Look like good face plates.  Not cheap though.

There is a recent post of a Japanese site that has the curved instrument lenses, I think.

Might be the stuff your looking for.

Great site - thanks for the link, haven't come across that one before. Lots of ways to spend your money! The lenses shown there look great but not cheap as you say. I picked up a complete spare tach on e-bay for consdierably less (still way too much though).

Yeah, it's too bad those gauges on the earlier, K0 models weren't a little more like the slightly later gauges. 

My 400F meters come apart quite easily, and in such a way as it enables just replacing the lense, or housing or what ever.  For example, I made a stupid mistake and scratched my speedo lens (around the edge when I was sanding the gauge without taking it apart).  I went to the salvage yard and found that an otherwise pretty rough tach ('72 bike) had the perfect lens for my '76 speedo.  So I replaced a thrty year old piece of glass with a 34 year old piece of glass and it looks like new.

All part of the joy of owning a K0 i guess

Thought I'd resurrect this thread and see if anyone had found a source for or decided to make their own early plastic "bubble" speedo/tach lenses?
