    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.

Petcock Stuck

On my 1983 GS750e, the fuel petcock seems to be stuck. It wont turn at all, and it is on the "prim" setting. Is it common for them to seize up and is there something I can do ti fix it? Or should I just be looking at replacing it. Thanks!
 
The only thing that could be stuck is the "O" ring that seals it. My only idea would be try to spray WD-40 in there, then gently force the thing to move. Be sure you are turning it in the right direction. Petcock rebuild kits are available & work great, but if you break the little lever off !!!!
 
Mine did that when I got it. You can (as prev. stated) spray some WD40 into the seam around the lever, give it a couple minutes to soak in, then use a pair of pliers to move the sucker to ON or RES (Preferably reserve, see bad news to follow)

Unfortunatly, in my case and one other I've heard of the seizing meant that the whole apparatus was basically toast, and the petcock started to leak gas as if it was on pri, which made my carbs spew a puddle of gas on the floor every time I started. Blech.

Best best is probably a new Petcock. It's like 60 bucks if memory serves but it's so easy to replace and such a bitch to fix I felt it was worth it.

That and the gas smell gets a little irritating.
 
I have the older style petcock on my 79/850 which are easy to rebuild. On the later style BE very carefull with the internal spring. If their is any pitting inside the housing throw it away and replace it
 
Thanks so much for your help. I went out and sprayed a little wd-40 in there and then I used pliers and it turned right away. I guess there really wasnt anything wrong with it, just a little stiff from not being used for so long.. THanks~
 
Glad to hear it's working again. Just be suspicious of it for a week or two until it's working 100%.
