    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.

Determine year/model from engine serial numbers

Is there a way to determine the year/model of an engine from the engine serial numbers? I have two engines. One I believe is a 77-79 gs750 (with round covers on the end of the valve cover) and I believe the other is a 80-83 gs 750 (with rectangular covers on the valve cover).

The two serial numbers I have are:
GS750-34314
GS75X-118417

I don't have the frames for either of the engines.

Do my assumptions sound correct for the years? I need to order some parts and I want to make sure I order the right ones.

Happy to post pictures if that would help.
 
The engine column is the number they started with for that models year. Same with the frame numbers.
