    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 know on my 82 GS650g (CV carbs), Clock-wise is lean, and counter is rich.

I start at 2 or 2 1/2 turns out from bottom.
Damn things are touchy too, i cranked them a tad too rich last week and nearly fouled out my plugs.

What carb? VM or CV?
CV out is richening.

81 gs 1000g
Note sure what carbs
after repacking and putting new ends on my mufflers I fing the plugs are sooting up so I thought I would lean the mixture up by adjusting the screws on top of the carbs that I think are the air pitot screws.
Am I on the right track or have I lost it.

Nope that would be the one. If you're sooting up the plugs the carbs were jetted already for the leaner pipes of you cut off too much air flow.
I'd get in the carbs and see what's in there.

What exactly did you repack?
My old megahones had nothing inside and the end caps had rusted away so I got some aluminium tube drilled some holes in it and wrapped some fiberglass wrap around it and stuck it in the empty megaphone , I the got some aluminium and cut it in to fit the the ends and drilled some holes in it, still pretty loud though,
so now I guess to air flow is restricted and my plugs are sooting up.
I thought I could adjust the air srew on top of the carns to lean the mixture out a bit.
 
that'll sort out the bottom end but what about the mid and top end?... likes been mentioned, open up the carbs and see what jetting / settings are inside. chances are needle and main had been changed for the less restrictive pipe and this will need changing back towards where it was originally
