    DO NOT SIGN UP USING hotmail, outlook, gmx, sbcglobal, att, bellsouth or email.com. They delete our forum signup emails.

    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.

My 79 GS850 runs great when cold. After riding about 8 to 10 miles the RPM's will drop and the bike will stall. After restarting it runs rough and doesn't have the smooth power it did when cold. It?s been in the shop several times. Carb have been removed and cleaned. Complete tune-up with new coils and the bike has electronic points. A mechanics told me it could the rubber o ring between the carbs and the heads in the intake I?ve not changed the o ring because none of the manuals show this part. Problem is very frustrating. I have other bikes but I love this bike. I?ve had since new. Any help with experience on this type of problem would be appreciated.
 
While you wait for a guy named Basscliff to fall on you with info, visit www.cycleorings.com (look for VM carb stuff) to see the o-ring that might be crying for replacement after all this time.

Does it start bogging more quickly if you're really cranking on the throttle? Could the float bowls be emptying?

Hi Mr. Jlake_Dave,

Have a look at this article (PDF file):

And I have never read anyone on this forum who said that they got a proper carb cleaning at a shop. Check out these articles:
