Mini Speedo

[jonirvine]

So, I have a '78 GS750 with the speedo ripped out (part of a cafe mod) and I'd like to add a tiny speedo, prolly this one:

Does anyone know if this would work with my bike? In particular, does the 750 have a electrical or mechanical that this would jive with? I'm pretty good with electronics not so good with the mechanics of a bike.

Any other suggestions for small all in one speedos that have other idicator lights too?

thanks, jon

Should work. I seem to recall from past use that the cable fits and the speedo drive ratio is the same as the '78 GS750. You'll have to devise yourown mount and wire the backlight. The matching tach will also work. BYW, these clocks (and others) are available from Mike's XS for less than the site in your link.

I've seen some Tach's with a use-range of 550 to 1000cc. I'm wondering if they'd still work "properly" with an 1100 bike? Does that extra 100cc do something to throw the reading out in some way?

That speedo works on my bike.

You will need some diodes to make the turn signal indicator and turn signals work. Basically, insert a diode to each of the turn signal wires coming from the harness (one is black the other light green), then pigtail them into the hot wire into the gauge. Otherwise, it works fine.

Thanks ChicagoBob (btw I'm from Burbank originally), that's good info!

Cinders, also great info. Are there specific diodes I need? One like this maybe? http://amzn.com/B000TK7XMY

I just installed this on my 550 yesterday. The ratio seems spot on the stock speedo and you can actually use the stock mounting points for the old gauges for the new speedo and tach, just be sure to put an extra washer on the bolt or else it'll rattle like hell.

BTW, I'm originally from the town next door to Burbank.
