    DO NOT SIGN UP USING hotmail, outlook, gmx, sbcglobal, att, bellsouth or email.com. They delete our forum signup emails.

    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 was wondering if i need to replace my reservoir going to a gsxr dual disk for my stock dual disc on a 84 gs 750?.I was bleeding the brakes but it seems to soft still?.I don`t want to go to a newer gsxr res.I like the stock look.Can a new res on any sport bike work?.

what matters is the mc piston diameter
if you can find out what that is on the gsxr that the brakes came off that would clear it
i THINK yours would be 14mm
 
btw, larger mc diameter would not change the feel of the brake lever but only its travel distance (will be shorter)
- but because of this the brake lever may APPEAR to be firmer, as it will "bite" sooner

Stock master for a dual disc GS is 5/8" - a smig under 16mm. Single disc bikes use 14mm masters.

In my experience, using a 14mm master on a dual disc system will result in a spongy feeling lever since there will be more lever travel to displace the necessary amount of fluid compared to a 5/8" master. Hand pressure will be less but travel will be higher. I recommend staying with 5/8".

I agree fully with Nessism
