Gs 1000 78-81 differences

[springystu]

Hi Guys,

I have had my 1978 Gs1000 HC for eight years and have just had to swap engines,
I have put in a 1981 Gs engine and carbs and swapped the ignition from my old engine (aftermarket electronic).
The old carbs had two cables for the throttle push and pull.
Do the new carbs only have a pull cable? And will a 81-84 throttle cable fit straight on and just blank the other hole in the hand throttle.
Also do the newer carbs have a choke cable as I already changed my switchgear for TL 1000 switches which have a choke lever already on them.

Thanks for any help

More info is needed such as what kind of engine you installed, what carbs, what country you live in, and so forth.

Here in the US market all the GS's received CV carbs starting in 1980 - one throttle cable and cable choke for all the bigger bikes.

Sorry

My Gs is a united kingdom model with manual choke and slide carbs with twin throttle cables i think you have answered my question as I have fitted cv carbs 54mm inlets so a standard single Et model throttle cable should be fine.
As for the choke cable I will get a TL 1000 or bandit one to fit the switchgear.
Is the timing the same on early and later gs1000 engines?

Cam timing or ignition timing?

Early bikes had points, later has electronic ignition, with seperate ignitor box. All details are available in the factory service manual. If you don't have one yet I suggest you download one from basscliffs site. No manual = No go.

When changing from the push/pull cables to a single cable,
all that I do is leave the not used cable in the mounts that hold the wire loom to the frame. (Into the atmosphere above the air-box)
The choke cable works on the CV carbs.
So, there is no reason to change the cables at the throttle.
