    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.

What a great site!!! Have had this bike for a year and enjoy it but want to improve it. I know my way around car engines pretty well but have no experience with bikes.

These are Symptoms.

cylinder 1 had a bad misfire. Discovered had wrong temp plugs. Changed them and runs much better. But cylinder 1 and 3 pipes were warm but not hot to the touch. Found vacum line from #3 carb was not connected to petcock. repaired and now #3 gets hot. #1 however still is only warm. When I pull the plug it has black carbon and is wet. others are clean and dry.

Does this sound like carb problem or firing problem? Any info would be appreciated.

Thanks
 
Welcome to the nuthouse, Basscliff will be along shortly to give you your world famous, mega welcome, in there you will find everything you need to know to restore your GS back to purring like a kitten.
It sounds like it is time to pull the carbs and give them a good dip and cleaning, you will find the tutorial on Basscliff's site, and repalce all the O-Rings while you are in there, you can get them from here, don't bother with the over priced kits from the vendors, they are not required.
Also be sure to check your valve clearances, they do tighten up and lead to all kids of running issues, that seem related to something else.
While you have the carbs off, be sure to change the intake boot O-Rings, they get hard and brittle with time and cause induction leaks.

Oh yes, and we like pics, lots of them, so don't keep us in suspense. :p
