    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.

Just purchased used 1981 GS650 four. Want to change oil. Do not have any specs, how much oil does it hold? I assume the trans and engine oil are handled by the engine oil!

Stephen
 
It should say right by the filler cap. It'll have the volume stamped on the engine case in milliliters.
 
The transmission is lubricated by engine oil. I have an 81 GS650GL (shaft) and there is a drain plug for the main engine oil, a drain plug under the transmission, as well as the filter cover which all should be removed to completely drain the oil. With my shaft drive there is also a final drive which is lubricated by 90W gear oil, seperate from engine oil.
I have a Clymer manual at home with the capacities for engine oil. It varies a bit if you change the filter or not. I will confirm this later but it seems to me 3.82L (4.04 qt) is the volume. That should get you close anyway. You can start it, let it run a bit, stop it and check the sightglass or dipstick to top it up.

The specs I have found said 3.3L or 3.49 US qt for engine oil. Do you know how much 90w gear oil goes in?


Stephen
 
:lol: 90w isn't so much an oil as it is a paste. :lol:

Seriously though, anyone with a Clymers that details the same model should be able to tell you... I know my Clymers has the specs for all 400 425 and 450 Twins from '77 to '87.
