    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...

    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.

Intake O ring size for an '80 GS1100E?

Was going to order the rings I needed from cycleorings.com but his a snag.

The intake O ring sets are 40mm, 38mm, 32mm, and 30mm. My manual says my carbs are 34mm... So which should I order? Again these sizes are listed for the *INTAKE* rings, not the actual carb o rings. I've already got the BS CV o ring kit in the cart. :)

Now the bonus question- I might as well grab the stainless fastener kit as well. Anyone know which size I need for my bike?

THANKS!!
 
lets see if this helps

77-79 750's, 850's and 1000's use 32mm o-rings and 16mm screws.
79 425's use 40mm O-rings and oddball 6x35 screws, which I don't carry. **
77-79 550's use 28mm O-rings (which I don't carry) and 16mm screws.
80 & 81 1100E and 750's don't use intake O-rings or screws (so you're off the hook!)
80 & 81 1000's use 40mm O-rings and 16mm screws. **
80 and later 850's use 38mm O-rings and 20mm screws.
81-83 650's use 38mm O-rings and 16mm screws.
80-82 550's " "
80-82 450E's use 40mm O-rings and 20mm screws.
82 & 83 1100's (2-valve) use 40mm O-rings and 16mm screws.
83-86 550's use a siamesed setup; they take 30mm O-rings, and five 16mm screws and one 20mm screw. There's a 'medley' screw set on the order page for these bikes.
85 700 uses 38mm O-rings and 20mm screws

See,,,hang around here long enough and you do learn something.....LOL

Gatekeeper- Where did you find that list? I'm hoping I didn't miss it somewhere, but it's likely seeing as how I'm WFH and trying to order bike parts at the same time...
 
In the words of Homer Simpson...

DOH!! :eek::oops::eek:

Anyway, the rings are now ordered. Thanks all!
 
Actually, that information is incorrect. It should say:
80-83 1100E models do not use o-rings. Hehe. :D:D
 
Check your intake manifolds (tubes) for cracking UNDER the clamps. ;)
