GS750L - Putting a fuel guage back on

[Arfius Arf]

Ive just bought a 1980 GS750L and she has had alot of the electrical bits removed. No electric starter, indicators etc but the main thing I really would like to put back on her is the centre console with the fuel guage. If I get the console and the wiring loom is it just a case of plugging it back into were ever the connector is for the fuel sensor/fuel float. If so were is it and what does it look like. Never had a GS before so it all new and exciting *Big grin*

...and I may even put some piccys up when I get her to how I want her

The gauges should just plug in. Look under the tank for the square plug with nothing attached.
As for the fuel gauge, look for two female connectors near the battery box.
And please post pictures of the "as is" condition that you found her in also.

£450 I bought her for... she is going to become a nice satin black with barb wire motif. Not a rat bike but not a chromey bike, somwhere in between

OK so i bought a fuel guage for a GS750. It has wiring with it that will plug into the female connectors near battery box and a square plug that will plug in to 'read' where the float is in the tank. Only problem is were is this to be connected. Took the tank off and the only thing under (attached to the tank) is the fuel tap. Is the 'float reader' connection actually on the bike or the tank? Below is a standard GS750 tank off EBay and this too hasd no plug on the actual tank. Im confussled and need to lie down

Anyone? Anyone?

I'd say your tank does not have a sending unit, could be the wrong tank, maybe someone swapped it out at some point ?

should look something like this

Also...your bike is not not an '80. It's earlier, say a '78 or 79.

[Arfius Arf]

It seems to be heavily modded. New speedo, revometer and bars amongsth other bits. So if it is earlier than 80 did they not have fuel gauges on them? If I get a later tank and put that on will this help me get a fuel guage back on the bike? Im confused your gonna have to spell it out for me I'm afraid ha ha

[Larry D]

The engine, carbs, kickstart all are from an earlier model than '80.

The 750 changed completely in '80 to a 16 valve, non-kickstart engine with different carbs.

If your bike was an '80 the engine would look like my '81 750.

[Arfius Arf]

Ahhhhh I seeeeeee..... still wondering if the earlier models were fuel gauge-less though. Just bought a fual cluster and no were to plug the friggin thing into now lol

[Arfius Arf]

Just done a registration check and its come back as manufactured in 1980 and first registered in April 1980 so I am proper puzzled now. Im in the UK so maybe thats made a difference? So confused now lol

[Larry D]

Your bike may have been left over from the previous year and registered incorrectly.

Yes, the 1st generation 750's had fuel gauges. This is what the fuel unit looks like, it is inside the tank and sends a signal to the gauge to indicate fuel level. This is of course from an '81 750, but, yours should be similiar.

EDIT::: I may be wrong about the fuel gauge.....sorry, I'm not that familiar with them.....I was looking at this "for sale" thread and there is a great picture of the gauge cluster. I can't see where there is a fuel gauge. Perhaps someone else will chime in to clear this up.

Im gonna buy a GS750 tank from the 80s with fuel sensor (and float inside) and just plug the fuel gauge into the sensor, wire it up to, maybe the headlight and see what happens. Cheers for the help... much appreciated

my 79 has a fuel gauge and the tank on your bike is longer by around 2" compared to my stock bike.Front calipers probably slightly more handy than a fuel gauge though.Finally just fixed my fuel gauge wiring and now it works.Doesnt seem to make the bike go any better

The front brake is with the bike, just not attached yet as uprated drilled disc has been added to the bike.

How does your fuel tank know when its low then as early tanks Ive looked at don't have a fuel sensor under the tank... unless its somehow connected to the fuel tap.

[daturat100r]

There are two wires coming out from the tunnel at the rear of the tank that connect to the loom just in front of the battery.I have had the tank off but have not looked at the sensor but hopefully doing my steering head bearings today possibly and will get a photo then.
