    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.

vacuum between carbs

Is there supposed to be a vacuum tube connecting carbs 2 and 3? And if so does the spring go in front or behind the hose?

thanks
 
No, there is no vacuum connection between any carbs. Kawasakis from the early 80s would link their vacuum lines for some models. What spring are you talking about? I think Basscliff's intro has a picture labeled "Where do these hoses go?"
 
Soooo, they are vent hoses not vacuum hoses. Assuming they are the same for VM carbs. There's a pretty beefy spring that attaches the throttle pulley to the carb mounting plate. It runs down between carbs 2 and 3 which puts it right on top of where a vent hose would connect 2 and 3.

The picture shows VM carbs. A 79 GS750 should have VM carbs. There are 3 nipples showing in that picture: the outside nipples are vent lines, the middle one (coming from the #3 carb) is a vacuum line which connects to the small nipple on your gas valve. The big beefy spring does not jump out and bite vacuum lines.

The big beefy spring is the throttle return spring.
