    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.

Low-idle problem on recently bought 83 GS650 G, many previous owners

Thanks for the feedback! A friend of mine had said that you have to do the vacuum test on all 4 carbs at the same time, the way worded it definitely did sound like I was going to try to test each separately as you interpreted it though. This friend (not the same aircraft mechanic guy) custom built bike back in the day and is a pretty handy (although unlicensed) mechanic who has a hydraulic lift in his garage and know the in and outs of most vehicles (especially older stuff). He had suggested that I could small glass baby food containers with water in them to built 4 cheap vacuum testing doodads myself. Obviously they would not be nearly as accurate as the real thing but would give a decent idea of which cylinder(s) were having issues.

In any case, $136 sounds like a very reasonable price to me to buy the real thing, and probably a good investment moving forward as I'm guessing it could be used on pretty much any motorcycle engine (or would it be any naturally carburated engine)?

GS750B won't downshift when hot. Oil, springs, swell, shift forks?
