Replacing clocks

[jack_ireland]

I have a 1980 GS750E with an 82' 1100 engine. Without trying to offend any GSX lovers out there I thoroughly dislike the 750 clocks (and square headlight unit) and want to replace them with an older 78 - 79 GS unit. Has anyone tried this, any known issues beside the rewiring work ?.

Thanks in advance.............Jack

Hi Jack, I am doing a similar thing with my gs1000. I'm fitting a Fairing from a gs1000S but cant get hold of the matching clock set and as I'm going to "17 wheels the Speedo would be way out. Does your bike use a cable driven rev counter like the GS? Have a trawl through ebay and see what you can pick up. I have just won these to see if they look ok mounted inside the fairing.
I plan to retain the electronic rev counter but will probably have to replace the Speedo as I suspect it to also be electronic, so a cable drive will be an easier solution to mounting and calibrating the electronic speed pick up.

You would probably do better to change over to the '82-'83 1100E instrument cluster. The wiring harness is probably going to be a closer match than the older bikes'. If you go with an '83 cluster you get the 140mph speedo. As far as the square headlight, probably the worst idea for cosmetics that the Japs ever came up with. A lot of early '80's bikes had them. I'd simply change over to the '82-'83 round 8 incher, which is probalby one of the best cosmetic details of that era motorcycle.

I'm gonna use 1150 clocks to replace the originals on my '79 1000S. Old gauges are too tired, and the 1150 stuff fits real nice inside the S fairing... I just need to convert to electronic tach, which should be a snap.

Just run the lead to the tach off of the negative post on one of the coils and you're done. I used a set of Bandit 400 gauges on my 1100 due to the 17" GSXR wheel and front end, and had to run the tach the same way. I used a bolt stuffed into a vacuum line, stuffed into a 3/8" fuel line, stuffed into the cable housing on the valve cover to seal up the tach drive. It looks a lot better than it sounds, and it works really well.
