    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.

Where do you guys go to get gas-resistant o-rings for your non-GS projects?

The local O ring and seal supplier, or Robert Barr. cycleorings.com

I'm not aware of any "local o-ring and seal supplier." At least, none of the places I've found that carry o-rings carries the fuel-resistant variety.

Also wasn't aware that Robert did anything other than put together the kits for our GSs.
 
Harbor Freight- NITRILE metric and imperial.
They hold up fine. I usually tear one putting the quick connects back on the Daytona fuel tank.

Z1 is carrying more and more o-rings. Not sure what bike you're looking for but they might have what you need. I've seen other online distributors posted on here but don't have a direct link to the thread.
 
Nice, guys! Harbor Freight had a great deal on an assortment. All the places I was finding locally would have to order viton ring assortments in, and they were looking for $40+!
 
Viton O-rings are best. I've ordered them from McMaster-Carr before as well.
 
For me it's Rocket Seals in Denver. I thought every city had an o ring oracle.
 
If you're on the cheap, harbor-freight has like a 100-pack or something, like 20 different sizes. As long as their nitrile, you should be okay. But since it's harbor-freight, there's lack of quality control, so double-check each O-ring before using. It's handy to have when you're not exactly sure about the size, or you're really in a pinch. I think they only cost like $10 or less.
 
I'd steer clear of those generic O-ring kits. They won't have the proper O-ring sizes in many cases. A proper fitting O-ring will have about 1mm of stretch when you install them. Stretch too much and it may work for a while, but the life span may be short. Personally, I'm not a fan of Buna-N for carb applications, although I've used them before. When I worked in the auto business we had a huge recall because some additive in the fuel, which was added years after the cars were originally sold, would attack the O-rings. Viton O-rings are more future proof and more reliable in general when it comes to fuel contact.
