    A Special Note about Email accounts!
    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.

I've been reading the factory service manual from bass cliffs website, and I'm a little confused about somethings I hope someone can help clear some things up.

I have a 79 GS 550.

I bought a motion pro carb sync tool.

One of my questions is the VAC line for the Petcock, what do I do with it before I sync the carbs? Do I plug it?

2nd, it's to my understand that there's no " factory " setting for the air pilot screw? It's different on every carb? For example for two turns? And I should try the highest idle method for this to get it right?

When I give it like a WOT response from idle it bogs, but if I open the throttle normally it revs up perfect. But any sudden fast throttle it bogs.

I'm pretty sure I have the carbs synced, valves adjusted, carbs rebuild with new orings, new carb boots, new carb boot orings, and cleaned/ lightly oiled air filter.
Thank you

Correct.

Mechanical slide carbs will do that.

No bike should choke with wot. How can that be normal?

That's just how they roll, on the models without accelerator pumps.
If you take a 1/4 second or more to open the throttle, it doesn't do it.
Just when you instantly snap it wide open.
It really never happens when riding, just when you are trying to make noise while stopped.
