    A Special Note about Email accounts!
    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.

Last fall, bike starting consuming gas and would not run unless throttle was wide open. So I figured it was time to do carbs. Finally pulled them.

Discovered that the plug I put over the vacuum port (when i changed the automatic petcock (1980 GS550L) for a manual one) was dryed out and cracking.

Would this be the cause for the poor running?
 
No. It would only effect that one cylinder, and only at low throttle positions.

Do the whole carb dip thing.
 
thanks

thanks

I have done much of the other recommended changes (regulator, valve check, etc) so I will do the carb dip.
 
Support the float tower when removing the pin so that it can't be broken. There is another repair thread on that currently.
 
The rotted vacuum plug certainly would affect performance in a negative way, but going forward with a complete carb overhaul will probably still be worth it.
 
thanks

thanks

Thanks for the replies and hints. I will be doing the carb cleaning as soon as I find the time.
