    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 have a 77 gs750 it has a 630 cahin and I am trying to count links, but I am not sure what I am doing wrong because for other gs's people are getting numbers like 110 and 88, but I count 50, what exactly am I suposed to count??

2nd a friend with an sv 650 droped a tooth from the front sporcket for a little more low end power, is there any reason I cannot do that on this bike??
 
Re: Chain and sprocket ??

A 77 GS 750 with #630 chain uses 96 links. If you have #630 chain, the distance on the chain from pin center to pin center will be 3/4" If you have #530 chain, the distance pin center to pin center will be 5/8".

Count side plates. There is an inside side plate and an outside side plate.
You count both.

Another note are front and rear sprockets resonably generic meaning do the same sprockets fit many different bikes??
 
I believe all chain drive GS models use the same sprockets. There are some newer bikes that use the same mount dimensions for their sprockets that the GS does, but I know of no newer bikes that retained the #630 chain size so I doubt there will be any new bikes you can cross reference sprockets to for #630 chain.
