    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...

    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.

Hi.

I recently ordered new intake boots and o-rings for my 79 GS850. Everything arrived in neat SGP bags labeled (correctly) with their part numbers except the intake flange o-rings, which came in a plain bag with no label at all.

Is there a way to tell the difference between common o-rings and heat-rated? My fear is that these are nitrile, and will break down quickly if I install them because of the heat (probably leaving a gooey mess).

Any advice would be appreciated, thanks in advance.

I agree, you can ask your supplier.
However, if you ordered them from cycleorings, you can rest assured that they are the proper item already.

Identifying O-rings

That is just the thing. I fear that they may have swindled me out of ignorance, malice, or just plain apathy. Whatever the case, I don't trust these what they sent me at face value and need to find a way to tell if they are any good or not besides installing them and having them fail.

For future reference I will order from cycle o-rings as you suggest since it sucks when you can't trust a vendor to send you what you ordered.

Thanks again

There's not really a good non-destructive way to tell the difference between the heat-resistant o-rings from Suzuki and "normal" o-rings.

Viton o-rings are made from rubber that it noticeably a little harder than regular o-rings, but the correct Suzuki ones are fairly soft.

What makes you think they would go to all the trouble of tracking down lesser replacements just to screw you over? It would be a lot easier to simply order the part numbers you asked for. No idea why they wouldn't have given you the SGP bag, though. As someone wiser than me once said, "Never attribute to malice that which can be explained by stupidity and sloth."

Are they the correct size? For a '79 GS850, the inside diameter is 32mm. In "inch" size o-rings, which are about all we can get in this metrically retarded backwater of the USA, a #125 Viton o-ring fits and functions just fine, although it's a tiny little bit fatter in cross-section.
