    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.

Hello good people. I want to move to a 530 chain for my 77. 750. From what I gather going through previous posts, 18 front 50 rear sprockets with a 116 link 530 chain should work. Does this sound right?. Also would any kind of shim/washer needed for the 750 B ? Tia.
 
Your numbers look good. You could go down on the rear sprocket to 49, but that's splitting hairs.

I'm not sure if shimming the front sprocket is needed or not. Some OEM sprockets have an offset built into them, in which case shimming is needed, since aftermarket sprockets are typically flat. Both 630 and 530 sprockets are the same width, (the 3 means 3/8" wide rollers), so you have that going for you.
