    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.

1979 Gs550- bike just had carbs cleaned (dipped) and bike still is idling poor and only with the choke up. New gas, new plugs, battery good, wiring good. Like I said I am a newbie so bare with me here but it seems as thought I am not getting enough fuel/air mixture here. Attached is a pic of the carbs- can someone tell me what the knob between the 2nd and 3rd bowl is- what is its purpose?​
 
it's your idle screw

did you do the dip, or was it done by someone ? did you install all new O rings, you can get them from www.cycleorings.com

did you bench sync, and then do a carb tune ?

hopefully you had them fully taken apart, completely cleaned and then reassembled....

If you go to the link as provided above, you can download the authentic Suzuki factory service manual for free.

As for your bike, please check the newbie mistake thread linked in my signature to see if anything rings a bell.
 
That's the idle adjustment. Make sure the mixture screw is 2 -2.5 turns out. Make sure the air box is sealed. Did they replace the intake O rings when the carbs were done ?

there is no factory setting for idle, you adjust until you get the correct idle speed, about 1100 rpms +/-
 
i had our local dealer do the cleaning- yes everything was taken completely apart and o rings and anything that needed replacing was done. Thank you all for your help I didnt anticipate an answer so quickly let alone several. appreciate it
 
if all the work was done by a dealer, why is the bike running rough, I'd take it back and have them do the work correctly, especially if you paid for it...

I just took the carbs themselves in. Sure enough I literally just adjusted the idle settings and sure enough with a little patience its sitting at 1100 rpms. Im up and running. thanks everyone- ray.
 
Beautiful......

Glad to hear.....

another satisfied customer....LOL
 
Make sure you synch them properly and adjust the mixture screws using the highest idle method. If you don't have a Carbtune or other vacuum gauge, then post up your location in your profile. One of us might be close enough to lend a hand.
