    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.

Cheap manual fuel tap - 44.26mm hole centers

Further delving has revealed that manual petcocks are available for the early XS650 (XS1, XS2) and the XS500, which have 42mm bolt spacing and it looks possible the normal jiggling tolerances might allow them to fit with a touch of a rat-tail file. However, a direct fit has proven to be the XS650 Custom/Special of 1978-84, according to one poster on the KZ650 forum (the KZ650 B1 1978 uses the same spacing) who owns both bikes.
As far as I can measure from the side on my tank, the XS650C/S uses about a 45mm spacing, so should fit with no jiggling, the hole diameter allowing a straight fit.
I'm going to pick one of these up in the next few weeks and see how it goes. Cheap enough to find out. It won't go to waste, as my own 650C/S is needing a manual tap anyway.

I looked at the first post didn't see which bike you were trying to find an adapter plate for, but the amount of research you've done in time, probably has paid for 3 manual Pingel petcocks, if they have the spacing your looking for. I've had one on my Kat since 1996, has reserve and served me well.

However, recently the gasket between the plate, ( I think I had to make one) started leaking. I pulled the petcock, and the screen was totally clean, even though I've never done any thing to the inside of the tank. The paint surface where the plate mounts to was uneven and flaking. Made a new gasket used Threebond 1211, and is leak free again.

Have a stock petcock on my wife's 1150, with no issues since we've owned it (1998).
