    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.

How I converted a 1980 non-lever petcock to a 1979 lever petcock.

Thanks for sharing. That looks like it will do the job but did the spacer need to be as thick? Just wondering.

Cheers,

For my application yes. The new petcock has a lever and it would not clear the bottom of the tank. Also the pickup tubes were about 1/2 inch longer and I didn't want them to hit the top of the tank. Also the reserve would kick in a bit too soon I think. 3/8 inch would probably have been sufficient, however the bar stock that the local welding shop had on hand was 1/2 inch.

Thats interesting because the petcock on my 1980 750L uses 50mm spacing. I was under the impression that all the 1980 petcocks without the lever were spaced 50 mm. I just checked Z1's website and the majority of GS bikes have 44mm bolt spacing except for the 1980's bikes that have 50mm. I like the idea of using the conversion plate, the 1980's petcock sucks.

That is why I decided to adapt the petcock rather than ship it back and order an 80 unit (though I still wish it had an Off position).
