    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.

Hey.
Im getting ready to rebuild my front forks because I have a leaking oil seal. I bought the oil and dust seal but upon reading the Clymer manual, I find that I would have to change the upper and lower DU anti-friction rings. Given that they are more expensive, Is it really necessary to change them? Its just that im supposed to do the job with a friend next sunday and Im not sure if the parts will come in time from the dealer.

Upper ring:51152-45400
Lower ring: 51121-45400

Most people get away without changing those.. they don't seem to wear out very commonly
 
Oh thanks, its just that I have a friend who is a mecanic that is coming to help me do the job and I didn't want to postpone the job to wait for the parts since the season is starting!
 
What the heck is a DU ring?


Anyway, unless a lot of crap has gotten past the seals into the fork, and/or the bike has done a LOT of miles, the teflon coating on these bushings generally lasts quite a long time. I've seen them in fine shape at 80,000 - 100,000 miles.

The upper ones see more stress and wear faster.
