    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.

'79 GS850 VM carb question

So I thought that the screws on the bottom of the carbs, not covered by the bowls, were the pilot screws, but after checking all the documentation available here, specifically page 3 of this document, it would seem that is the pilot fuel screw and the pilot air screw is on top of the carbs.

I can't seem to find anything on what impact the bottom screw has or mixture and what is the factory default, and which may makes it richer.

I can't even find it on mikuni's pdf

Thanks for your time!

Rob, if you screw the fuel screw in the mixture weakens and out it richens.

You're not meant to play with those screws - the government will come round and arrest you for polluting the atmosphere and poisoning polar bears if you do. But if by chance your screwdriver should fall in to the slot then about 3/4 of a turn out from lightly seated is standard.
 
the diagram in your link is correct. the fuel pilot screw is on the bottom of the carb, at the front and the air pilot screw is up top, on the side
 
wow yeah look at that right there page 5 and 6... i saw that and didn't put one and one together.

And thanks for the standard settings!

Thanks all for the help!
