I contacted Pingel asking about a vacuum operated petcock, and they sent me the following information. I have not yet followed through with them. I began thinking about changing to a vacuum unit after forgetting to shut my Bonnie off overnight....several times. Luckily it didn't leak, but ....

Here's the info from Troy at Pingel:
Hi Bob, I think I can get you fixed up with one but I will need you to verify that the space between the two bolts that hold your valve on is 34mm or 1.338 inch. This is from center of bolt to center of bolt. Here is a little drawing attached, Then I would need to know if the valve is on the right or left side while your sitting on the bike. Then I need to know in what direction your fuel outlet faces, front, back or intword the engine?
Thanks.
Troy

Note on hooking up the vacuum unit - My W650 uses a vacuum petcock. A single vacuum line goes from the petcock to a "T" connection. From there, vacuum lines connect to the right and left Keihin CVK carbs (like ours). Unlike the ones on our Bonnies, these petcocks have three positions (1) Normal (2) Reserve (3) Prime - only used in the event you have run the bike totally out of gas and want to fill the float bowls.
