    Carb identificaition help

    Hi, I have a 1983 GS400E, it is an 8 Valve TSCC motor so it is a totally different motor than the normal 400.

    I have noticed a lot of parts are the same from the USD GS400E, so would the carbs also be the same?

    My 400 puts out 44hp which is more than the 450 does so maybe they are??

    I cant find any numbers but they look exactly like Mikuni BS series carbs, but which o-ring kit to buy?

    Thnks!

      Yep you guessed correct on Mikuni BS series. They are a Mikuni BS34 x 2.

        well I dont have an issue with the price of the 4 carb kit anyways, but the only thing I see about twins on there is this:


        Sorry, but all I have for the 450's are the intake O-rings and 20mm fasteners. No carb parts.

        Plus I am still not sure if the 450 parts are the same as my 400...

        I emailed him but he doesnt know anything about the 1983 400e...

        Any Euro/austrailia/japan guys on here able to find out? Intake o-ring size and fastener size? And whether the 4 carb BS series kit on cycleorings.com will work?

        I know I can measure, but I would like to have the parts BEFORE I tear apart a bike that runs pretty well.
