    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.

'81 GS450 520 Chain Conversion

Can anyone confirm that the following parts will work to convert my GS450 to a 520 chain?

Vortex lists this front sprocket as a 520 conversion; Vortex part# 3270-16
https://www.vortexracing.com/shop/sprocket/111/

I can't find the thread right now, but I remember reading that the rear sprocket for an '82 GS300L will bolt right up to the GS450 wheel and it is 520 pitch.

Am I on the right track?

I was able to pick this bike up for $1150 with less than 6000 miles on the clock.

I found the thread that talks about this conversion. Just scroll down to reply #370

When comparing the drawings on the JT Sprockets website, the mounting holes look different to me. Am I missing something? I'm just trying to find a setup that is confirmed to work before ordering parts.
