    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 don't have a service manual, and was wondering how to adjust the rear shocks. They are in the highest position from the last owner.

THanks
 
For starters a service manual can be found here http://members.dslextreme.com/users/bikecliff/
Generally service manuals won't show adjustment. The owners manual would be a better place to start.
Page 95 of the 77-82 GS550 manual shows the original shock.
As a general rule the rear shocks are adjusted with a C spanner with a hook at the end that engages the stepped collar below the spring. You just turn it to change the preload.
 
The best adjustment you can do is replace them with some modern shocks that actually work.

True this. The difference between working shocks and failed is like night and day. The mere fact that they are jacked up to the last would suggest that they are lacking. Pushing hard down on the seat and letting it rebound will give a fair idea of how much damping is there.
It's possible that you don't have the originals. Is there a logo on them ?
