Oddball GS1000 Carb - parts?

[dubwicht]

I have a 1979 GS1000L and my carb is unlike any I have seen. It has this structure on one of the bowls. I can't find this on any parts diagrams and need a some parts including the spring and a washer to prevent water from getting in. Has anyone seen one like this and if yes, do you know where I can get parts? Thanks.

Those carbs do not look like the originals that came with your bike.

The 1979 carbs, for one thing, are VM26 mechanical slide type.

EDIT: are those Keihin carbs? Maybe from a CB750?

And are you sure your bike is a 1979 model year? Bikes with manufacturing dates after about 8/79 are most likely 1980 model year.

Here is another photos

This is a Canadian bike. Not sure if it makes any difference.

No, it doesn't
Definably not stock Mikuni
How about pics of the name and markings?

Never seen a gs with air cutoff valves. Throw up a pic of the full rack. Im suspecting keihins

In the other thread, about the throttle cable, it shows mechanical slide carbs with a butterfly choke. Most likely Honda Keihin carbs from an earlier CB750.

They are Kehin and I may have done something stupid - I have a CB650 and may have grabbed the wrong carb set.

The carbs you need, should look similar to these (assuming your bike is truly a 1979)

I have a the proper set. One of those days. They are a similar style but different manufacturer. Thank so much.

Yep, that looks like an accelerator pump diaphragm with the lower cover and diaphragm/push-rod removed. The photo on the throttle cable thread shows that the carbs are mechanical slides, the butterflies are upstream of the slides which means that they are choke plates.

FYI - Consensus from the Honda/Keihin world is that you can disable air cut off vales and be OK.

But as others have mentioned, that is an accelerator pump. Hard to say if you could live without that, assuming you can get the Honda carbs to otherwise work on your GS.
