    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.

hmm. i just did a search and bamboozled myself silly..and figured i better ask someone that's been here and possibly already TRIED it haha.
I have a 82 GS650L.. it is single front disc, and the rotor is warped slightly. well it really bothers me hahaha. and I just think dual is .well KOOL and prolly better stoppers.
I just today happened upon a tired, rusted, barnbiketom of a 79 GS750 PARTS BIKE with dual disks but the forks are very badly rusted. the fork upper tubes on the 650 are minty fresh. I know they are both 35mm, i measured 'em!

so.... will the lowers interchange? they look good but I don't wanna tear em apart to find they are internally different or won't work for somereason. If the y do, then I'll pull tem off, either polish or better yet powder coat em BLACK MAYBE>> then use the dual disc front wheel (they look the same.MAGS ) and the hose connector splitter etc etc etc. no problems with the calpers etc i can rebuild them too they will need it!!
sorry for so long but long story short. will the parts interchange so i can use my upper tubes with the lower legs from the 750????:dancing:
 
Hi,

Did you compare part numbers?

CLICK HERE to download a PDF guide for the Alpha-Sports site cross-reference.
(Note: If the newer part numbers return no results, use the older, superseded numbers.)

Thank you for your indulgence,

WOW thanks that is a great way to check part#s. in looking, the leg is different the damper is different, the fork seal different, etc etc etc. BUT I may just have to take them part anyway.. it may be something thatwill work.however it is supposed to be only that year.. but I wonder if it is merely a cosmetic issue or something else that will prevent it from working.. maybe someone else will have tried it and let me know it won't work:mad:

thank you cliff.. much appreciated!!

The tube diameter is the critical issue

The fork seal should note what the diameter is 35 or 37mm
 
I have a pair of '79 750L lowers that are indeed different from my '80 850L lowers, but not so different that they couldn't be used. The left side didn't have the bolt hole boss for the speedometer cable, so I had to use a zip tie to hold it in place. Other than that, everyhing else worked just fine.
