    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.

I just bought 1980 GS550L that's been sitting for 2 years in garage. First issue off the bat the gas leaking through old o-ring from tank to petcock and ordered one but before I try getting this stock petcock going, I have seen the name "dreaded" petcock for these 1980's a few times now and was wondering if I should or if its even possible to change this petcock out for something that's not so "dreaded"?
 
When I had my '80 750, I put on a Pingel and an adapter plate. It worked great but was an incredibly tight fit. The nice thing was that it was a high quality part and it had a 'reserve' but they've gotten pretty expensive these days. If you want to get an after market vacuum petcock, I'd suggest you buy it on Ebay.....they're cheaper, made in Japan and are probably pretty high quality. (The one Tom mentioned is probably the same thing, but for more money.)
 
There isn't much out there that swaps straight in. Things like an XS650 unit has the same spacing but when you read of the Yam guys swapping these out it seems rather pointless.

As said above, just get a new replacement part. That's what I did after trying to fix the one fitted to my bike and and suffering a flooded engine after the failure of a second unit I reconditioned.
 
I wouldn't buy anything from him.
I bought a petcock from him 5 years ago, fast free ship. Unit is decent quality probably made in same Japan factory as a suzuki oem. I have no idea about other stuff that he offers.
