1977 400 carb info

[Bcrusep]

Does anyone know what size the carbs were on a 1977 gs400 and where i can get a rebuild kit for them? Thanks

I'm not sure the info, but do you need a rebuild kit? Can you get away with reusing your hardware and just replace o-rings and gaskets? Everyone around here will tell you that OEM is better than rebuild stuff and unless things are beaten up beyond use, you can just replace rubbers and gaskets. If your jets aren't broken or flattened or whacked, cracked and all that, you should just keep them.

check out this website for replacement parts for your carbs:

here's also a link for stainless allen head cap screws for the intake boots:

according to this website (http://www.suzukicycles.org/GS-series/GS400.shtml) your bike has Mikuni BS34 carburetors.

Does any one know what size the intake o-rings are for the gs400 1977? On cycle 0-rings you can choose from 28,30,32,38 or 40mm. Thanks
