Are 1977 GS 750 carburetors different from later models

[Guest]

Hello,

First post!

I recently purchased a 1977 GS 750. For various reasons I needed to pull my carburetor and give it a cleaning. As I combed the web for resources, I noticed my carburetor looks different. There is no diaphragm or butter-fly values, were the first year's carbs different? Anything special I need to know?

Also, having the classic problem of not being able to get the air box back on. Boots won't go on it square, about ready to say screw it and go to pods. But I hear that's bad if you have CV carbs, do I even have those? Would this be an OK candidate for pods?

I've ordered an old Clymer: Suzuki GS750 Fours, 1977-1982: Service, Repair, Maintenance guide off Amazon. I imagine I will get some answers there but I thought I would check the collective wisdom of this place first.

Sorry if this has been asked before. I did some searching here and did not seem to find it.

Any help or direction would be appreicated

Go here -your bike has VM carbs , later carbs are CV . Best to assume your bike has had neglected maintenance, so reinstalling airbox at this point might just be good for practice, as carb cleaning likely is on your-to-do list

That is exactly what I was looking for! I cleaned them, but not to the extent this .pdf goes to. I really appreciate the quick response!

Between this forum and Bassclif's site, you've found a gold mine!

By the way, the "later carbs" that are CV-type started with the '80 model year, so your '77 carbs are the same as the '78 and '79 models.

Jetting varied from year to year and was based on ENGINE numbers. Other than that 77 thru 79 are the same bodies.
