    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.

i need to get a rear sprocket after this year what would be a good size regular riding, but till want the power range i have for when i want it
 
never really counted it maybe i should lol, meant create my own possrt not hijack this one
 
pretty sure its stock size tho, looks like oem material

The stock sprocket and chain size on an 1100 is #630. You can check to confirm that you still have stock by measuring the distance pin center to pin center on a link of chain. #630 chain is 3/4" pin to pin. #530 chain is 5/8" pin to pin.
 
There are at least two people asking questions in this thread, which is a great way to ensure everyone stays confused.

Anyway, when the question involves chain and sprockets on a GS, the answer is always the same: call Z1 Enterprises. If your bike originally came with 630 chain, they have the info and parts needed to convert to modern 530 chain, which is cheaper and more widely available. Of course, you can also change your gearing around if you like when you make the swap.

Back in the '80s, beefy 630 chain was needed on the larger bikes. Nowadays, 530 chain is many times stronger than it used to be.
