    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.

Where is the oil pressure regulator ???

I have an 82 GS450 with no oil pressure.
I have hooked up an oil pressure gauge per the shop manual, and at 3k I have about 5 psi. Installed new oil pump and filter with no change.
Suspect the oil pressure regulator is stuck open, but cannot find the reg.
Dealer said drop the pan, and it will be right there, wrong !!

Any help would be appreciated. Thanks, Greg M
 
I just looked at the crankshaft fiche for your bike and I see plain bearing inserts, so it should be a higher-pressure oiling system than 5 psi. :oops:

Not sure exactly how much higher, but the manual for the 650s calls for 43-78 psi at 3,000 rpm.

I don't see anything about a pressure regulator, so there is a chance that the oil pump itself needs to be replaced.

Regulator bolts to the oil pan - item 6 or 7.

Drop the pan and see if the screen is clogged, a number of riders found their sump loaded up and restricting oil intake
