    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 bought a long stored 77 GS750.

I have cleaned up the carbs and am working on the brakes. I feel like things are coming along nicely...but it has a 4 in 1 header and this baby is loud. Is there any way to quiet it down without replace the whole exhaust system. The guy I bought it from said they were kerker headers but all I can say right now is that they are black and oh so very loud.

Re: about the noise

If the muffler has a removable baffle tube, you can re-wrap it. Also, J.C. whitney sells some Emgo replacement mufflers that would probably work and they are not too expensive. About 20 to 50 dollars if I remember correctly.

about the noise

The problem is that it has no baffles at all. A 4 in pipe that is empty. I would like to find a baffle kit or something to tone this girl down just a little...or maybe a lot.

about the noise

It does have remarkable resonance though.

Do you think pipes like that will hurt the bike?

Without any backpressure it's going to be really free flowing and cause a lean condition of not jetted accordingly. You can run open pipes (not legally around here anyway) as long as you're jetted for them.
