Morgan .. No, that's an entirely incorrect tach.
You will need a Smiths chronmetric RC83 8000 rpm tach driven with a 3' 2" cable and a 70549/4 tach drive. BTW, this is also the same tach and drive used on the A10 Road Rocket

Be alert when looking for a used tach drive as there are other 'look alike' types for other models that won't work. Phil Pearson makes and sells a nice reproduction drive for Goldies, if you need to buy new.

Ask around and you may find a good used drive. If/when you find a used one, ask me for my method of flushing and pumping fresh grease into the gear box.

Let us know how it goes.

Morgan, I am no expert but I have two Goldies ('56 and '57) that came with Chronometrics and the faces are different from the one you pictured; see
http://home.pipeline.com/~twotyred/Roadster10.jpg

The scale is "upside down" compared to most other instruments, with my zero being about where your 12 is and the needle traveling clockwise from there. I believe the scale on mine goes to 8,000 rpm, not 12 as yours does. I don't know about the factory dirt trackers, they may have been delivered with a different tacho. One imagines that the specification of the dirt trackers varied considerably by the time they arrived at the track, so "originality" may be an elusive concept.

If you want a better picture I can take one tomorrow, but if you're trying to duplicate the original dirt track racer equipment there may be little value in comparing with mine.

Cheers
Rick F

Hello Morgan!
Also I do not know what this tacho is from but 12000 rpm seems an awful lot to me (at least for a brit bike). The tacho drive for Gold Stars have a rotation ratio of 1:1, beware there are several other couting 2:1. this means for every rotation the mag does the cable does one too. You can easily check this by turning it by hand. This ratio sometimes is stamped on the outside of the drive. Generally two drives exist:one is made by Smiths and is made from zinc-alloy; others and more common ones were made of heavy bronze. The instruments Dave refers to are printed RC83 on the face and rpm goes to 8000 on the genuine Goldie tacho. No provision for a light bulb is made to these instruments. Expect to pay at least 100-150 bucks for the drive and 250-350 Euros for the instrument depending on condition, sometimes more. That is if you can find one. IŽll keep my eyes open.
Regards from Hagen

If the post works the a proper tacho knee drive and tachomeeter is on the way from Kansas.

Steve McGee Sr and I made a swap. I sent him my 12000 tacho above and will support him with oter stuff. I'm closing this thread and will open a new to show what I've got when it arrives.
Thanks all for your input bigt clap
