Speedo Upgrade for 1975 R75/6

[pkboxer]

This is my '74 with a russian/chinese bucket.

/5 headlight ears for the mounthing.
/6 ignition switch installed.
/7 electric tach in instrument with homemade face.

Speedometer? Err, in 3rd gear the revs are pretty close to the speed.

Excellent! What tach did you use?

+1, and where'd you get the chinese/russian bucket???

The guts of the speedo that came with the bucket was junked and I put a /7 electric tach in the housing.

Printed the face plate myself to match the spacing of the /7 tach but with a vintage look.

Bucket is from E bay, maybe $75 for it with the light and instrument.

A standard 7" halogen headlight fits so the size is bigger than the /5 light.

Airbear, I think he's Airbear on this forum too, has the same type bucket on his but with an Acewell speedo unit.


Edit - Charlie is "Brun" on this forum, here's his...

OK, you're my hero. This is exactly the type of build I want to do. I wish you had made a thread chronicling this beauty.

I am so excited I might pee: is the /7 tach what is actually calculating the speed for the speedometer? I ask because I do not see a tach in your photo.
The bucket you purchased--not from an Airhead, I take it. Any idea what kind? I love that you opened it up and put a new face on it. You must be one of those "weird airhead guys" too.

It was so slow developing it wasn't much of a build more a progression.

Fitting everything into the bucket and making it "neat" on the inside were the hardest parts.

The wires are color coded and match the colors on the junction board but I still documented the dismantling of it.

No speedometer, just a tach. Sometimes use a GPS Speedo on trips, mostly just ride with the flow of traffic.

Think the search was "ural headlight" or "russian headlight" or the like.

For those wanting something like a /5 bucket, there is this from a ChangJiang 750. The bucket is quite deep, so you need to organise some longer ears. The speedo hole is 85mm (3 3/4") diameter.



I made some s/s ears and have since painted the chrome rim black.



Google 'CJ750 parts'. There is also a version without the 'eyebrow'. They are about $65 for a complete headlight, including the ignition switch. The headlight itself is pretty ordinary but easy to replace with a sealed beam unit. The ignition switch includes a spring-loaded starter, and works very well.

I fitted an Acewell in a fabricated adaptor plate and I'm happy enough with it, but that 85mm hole will take one of these GPS speedos - available in metric or imperial, with choice of face colours. Google 'Speedhut'

Thanks a bunch. I'd be happy to see anything else you feel like posting about it.
I'm thinking of tearing apart the stock /6 tach, and putting those guts in a new, or at least more attractive housing from another speedometer. hmmmm. If anybody else has done this type of thing, show it!

Hey Brun, thanks for the specifics! Very useful. I'm going to get to work on the computer.

I believe this is fiberglass. Cheaper than rehabbing something old...

2nd item down. They have a speedo or tach you can use too.
