Nope you are the first.....
If you disconnect the vacuum line from the petcock, then you have to plug it off in some way or another, otherwise you'll create a leak which will screw up the VOES.
Seems to me the best solution there is to just toss the old lines completely and replace with a single line from the carb to the VOES.

If it's automatic, then you've got the vacuum type.

When I had 1/2 tank of bad gasoline day before my road trip to MT. Washington NH, I was stranded 40 miles from home. I ended up pulling the entire petcock out the bottom to drain the friggin' tank. That was my first experience with vacuum fuel systems. What a stinky job that was. To top it off, the station manager busted my ***** giving me my money back until I showed him a taping pail of crappy 1/2 gas, 1/2 waterry goo.
I came inches from pouring it over his turban....grrrrrr.

Imagine if that **** happened to your car, you'd be calling a tow truck. Luckily it was only in your bike.... I hear it's a real bitch to Prime that back up again with that vacuum petcock. If you had a Pingle it would not have been an issue.....
