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...

    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.

Carb Question

I finally got my o-ring kit and went to clean the carbs on my 1978 gs550E and the first thing I noticed was that there was no small connection hose on the vents between # 3 and #4 carbs. Shouldn't they be connected? The second thing was that there was no spring on the pilot air jet. Can you use a spring from a pilot fuel jet for that or should I try to find a spring? If so does anyone have an idea where to get them. Thanks for all your help and I hope this thing runs when I get done but then again it didn't run before I started.Anyway Happy Thanksgiving guys.
 
Do you mean pilot fuel SCREW and pilot air SCREW? If so, yes, you need a spring on each adjustable screw in order to keep the screw from turning due to vibration.

Regarding the connection hoses, yes, you need a small piece of rubber to connect the vents between #3 and #4. Any old piece of fuel hose should do.


BTW, I have a box of spare parts for VM22 carbs like those on your 550. Please detail exactly what you need and I'll check to see if I can help you out.

Sorry about that it is the pilot air SCREW that didn't have a spring on it. Can you use one off a pilot fuel screw on it or is the tension on it not right to use?

I believe the springs are different size. I trust you are going to fully disassemble the carbs and dip them right? If you take apart one of the other carbs you can see the difference in the spring size.
 
I did notice that the air screw spring is a little shorter and a little stiffer than the fuel screw but do you think it will hold the screw to keep it from moving when I put them back together.If not is there anywhere I can buy just the air screw springs? Thanks for your time.
