    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'm chopping a 82 gs 650glz and just finished the carb rebuild but now the bike idles at 12,000. I tried adjusting to the top screw but it didn't work. I'm just a little lost. I think i need to adjust the air screw or air jet(whatever you want to call it) at least that's what the manual says i have to do but the manual sucks and isn't very descriptive.
 
12,000 rpm idle? Sounds like you got a hunk of weld splatter from the oxygen lance on the throttle linkage.
 
didn't use a cutting torch. cables are clean. check that already
 
Did you do a bench sync? and do you mean "1200" for your idle ?
 
12,000 rpm is a tad beyond redline on these engines...........Does it have an airbox, pods, or what? If it's sucking a lot of air, really lean will cause the idle to go up and up.............
 
i did mean 12000 but i fixed the problem. and now its at 1500 or so still needs a bit of fine tuning but now the gas won't turn off at the peacock . any suggestions on how to fix this.

The peacock?:confused: The gas petcock on most of the GS bikes are vacuum operated, so there is no real "OFF" position. They have "ON", "PRI", and "RES", sometimes only first two. If the fuel flow doesn't stop without vacuum applied, you've either got the petcock in the "PRI" position or you've got a leaky petcock.
 
sorry meant petcock not peacock (really spaced on that one). so the vacuum pressure stops the gas form constantly running?

Vacuum opens the valve to let the fuel flow by gravity, lack of vacuum shuts it off.
