    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

I am hoping to find a carb rebuild kit for my bike. It is the strange one with only 2 carbs. I have had a hard time locating a kit for it. Any and all help is appreciated.

Get new OEM float bowl gaskets from a local dealer or a place like Flatout:
http://www.flatoutmotorcycles.com/fiche_select.asp

You need the (BS) CV carb o-rings kit from Robert Barr at:
http://www.cycleorings.com/

You should be able to re-use all the other stuff - jets & the like...

Also get the intake boot o-rings from him as well (measure them & choose either the small ones or large ones, or just buy them both & save the hassle). Replace the phillip head screws holding the intake boots on with SS allen heads too.

Robert may tell you he doesn't carry o-rings for your carbs, but I have used them on the same bike & they work fine - you will just have extra rings because those funky 2 barrels don't use the same number of o-rings as the other CV carbs...

Make sure you completely disassemble the carbs & dip them to clean them thoughly - not doing this will just cause you pain & frustration & you will be doing it a second (or third) time if they are not clean.

The guide to carb cleaning is here - not exactly your carbs, but you get the idea:
http://www.thegsresources.com/gs_carbrebuild.htm

Don't forget to adjust the valves as well - yours are easy with the 16V head (get a new valve cover gasket too)

Welcome to the forum - good luck & keep us posted on your progress.

be carefull taking out the diaphram if you split one suzuki want $70+ very hard to source elsewhere..I bid on a ziplockbag full of 550 carb parts on ebay and luckedout for $15
 
Thanks for the info. I am working towards a carb rebuild on a 1983 GS550E with these unique twinned carbs and your information is very much appreciated.
 
Good info here, thank you very much. A quick question, IIRC someone mentioned some time ago that these engines run better with a slightly larger float bowl, achieved by slightly increasing the thickness of the float bowl gasket. Does anyone have any experience with that?

Do yourself a favor, restore the bike to STOCK and enjoy the fine work Suzuki did. Messing around with silly things like thicker gaskets is a recipe for heartbreak.
