    A Special Note about Email accounts!
    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.

Knocking sound

I just bought a 1981 gs650e and I noticed today that in 5th gear there is a knocking noise, and only in 5th gear. The noise increases with speed. Does anyone have an idea as to what would be causing this noise?
 
You might want to try a 92-93 Octane, and see if it stops. Worked for my last bike.
 
Re: Knocking sound

What is your oil level in your sight glass, how old is your oil and what oil are you using? Also, have you removed your engine countershaft sprocket cover and checked to see that the hold down nut on your countershaft sprocket is tight?

I just changed the oil(10W 40). The oil is at the full mark in the window. Doing this had no effect on the sound the bike makes in 5th gear. It is possible that 5th gear is going?
