+1 Yes, shut it off

 

Because it was quick and in two years I have not had a problem.
But, I'll revisit this and look to plug it.
Thanks

 

I have since discovered a hole in the diaphragm the vacuum petcock.
( I had to take it all apart and stretch it a whole bunch, but I saw a hole )

So I bought this stuff called Seal-All (gas/oil resistant GOOP) and made a new seal on top of the old rubber. put it all together. and works like a charm.

I'm not sure what the lifespan of Seal-All is. I may have to send the company an email.

But I also plan to get a high flow petcock, I felt a chug after accelerating for quite a while, and around a corner and stuff. but nothing major, and definitely no stalling!

 

So when did they start using vacuum actuators? I just ask because I wonder if my bike has one. I always remember to shut my gas off at the end of the night when storing my bike, but what about when you just go out to eat for a lil over an hour?
Shoot, I got so paranoid about if I shut my gas off that I would go back and double check! Now I wonder if I even have to worry about it that much...

 

I absolutely hate vaccuum petcocks! Had one fail on a Kawasaki at 80 mph, blew gas all over me and bike, left me stranded 9 miles from a town.I replaced it with a non- vac unit from older Kaw, never had an issue.
My 01" Harley vac petcock took far too long to get fuel when going to reserve, it almost got me killed on the highway. It takes 5-7 seconds to get enough fuel into carb at 70 mph, way too long in the middle of a pass with a 5 ton truck barrelling down the other way. Stock vac petcock can deliver 22-23oz per minute, not near enough when you need 4 ozs right now! I replaced mine with an EMS unit that flows 88 oz/minute, now reserve is almost instant! If you have modified your engine, it is almost a must to assure enough fuel at WOT too. The EMS supplied enough fuel to run my 95" Supercharged (140hp) to 160 mph!
You do have to teach yourself to turn the petcock off, but any squirrel should remember that, right hehe. FWIW Fastrider124

 

Don't do that. Run 1 vacuum line from your carburetor to your VOES switch. Just Lose the T connection under tanks that go to petcock. VOES still gets its vacuum and you get direct fuel flow.JUST DONT FORGET TO TURN GAS OFF. don't be "that Guy".

 

Pull the tanks and run 1 line from voes to carb. A nice line. Voes requirements are met and ya get your gas. No more being stuck in yellow stone park.lol that poor guy.been there,well not there, but on road.....a motor getting no Gas when you have 1/2 a tank SUCKS..hahaha .thanks for sharing
