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...

Can't find "DU" rings!

Does anyone know where to purchase new Anti-Friction "DU" rings for front forks?
I'm doing a rebuild on a pair of (according to the ebay seller) '78 GS750 forks and need to replace the "DU" rings.
However, according to the micro-fiches at Bike Bandit.com there are no "DU" rings on '77-'79 GS750 forks.

Edit:
According to the Bike Bandit parts list, the first GS750 with the "DU" rings is the 1980 GS750 ET and LT.
However, both of these forks are Leading Axle forks whereas mine are straight.

Will these work?
Any ideas?

Thanks!

Oddly enough, I was just reading that section of my manual (granted, this is a GS550). According to this manual, Suzuki did not start using the DU rings until model year 1980. That seems to match what you're seeing in the fiches as well.
 
They are not available in any case far as I know... They don't tend to wear out in my experience.

By the way... couldn't put a hand on that MC, sorry!

I have one from an SV650 that would work but looks completely different. Adjustable lever, round reservoir that you'd have to mount etc.

No worry's Dan, thanks for tryin! I'll just keep hunting e-bay.

Bike Bandit has DU rings from '80 and up available.
Does anyone know if they'll fit my forks?
I'm assuming a 1980 GS750 has 35mm forks, they're just leading axle which is why not many people use them when upgrading.... correct?

Yeah... my manual only mentions them being used on the TSCC models but they're still not listed on Bike Bandit's parts list.
 
Don't quote me on this but I think they're out of stock with no more coming but I've been wrong before!! :)

If there is no play in the fork then you likely don't need them.

Dan :)
 
I currently have my fork apart, I will take a picture of the DU ring for you.
