    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.

Help ID'ing fuel tank/fuel cock

Bought (what was labeled as) an '81 GS550 petcock for my '80 GS550 - the fuel cock is slightly too long and about a mm thinner than the tank opening. The thread pattern is also closer together than the threads on the tank (so I can't attached the fuel cock even if I squeeze it in) so I'm now wondering if my tank is truly an '80 tank. Any more experienced members have any insight? Before I buy another fuel cock I want to make sure I'm buying the correct part for my tank

Thank you!

What is the center to center distance for both the tank and petcock.

BTW, buying a dirty old petcock is almost as bad as recycling condoms.

Tank: Center to center of the threads is 2" (50mm)

Petcock: Center to center of threads is 1.75" (44mm)

I know I know but this was $14 shipped so I couldn't pass it up (which would explain the occasional itch)

Does anyone know a non vacuum universal petcock with 50mm c/c flange? I'm really trying to avoid paying for the $80 OEM part...
