Come to think of it, no one seems to have complained about fuel starvation on a 01+ that I recall.  That could just be because they are newer and not all junked up yet, or that they're better.  (I'm certain they are different.)  The mounting looks slightly different, but it should be no problem putting a 01 petcock on an earlier bike.

I had fuel starvation all the time on my '92, and it hasn't happened once on my '01, even during long high-speed trips loaded with a passenger and luggage.  Whether that's because of fewer miles or because of a different petcock is anyone's guess.  However, the '01 petcock is definitely different (at least on the outside).

I found a simple way of modifying the stock 2004 - 2007 petcock so it can be converted to a manual operated system.

Regardless of whether you buy a new frame petcock with out a vacuum line or modify the old one to NOT use a vacuum line, what do you use to "plug" the port on the carb?

Thanks

A vacuum cap. Another option is to cut the line and plug it with a screw.

Doesn't the Pingel petcock have a valve handle the faces straight down out of the tank and can be reached from below, with the tank in place?  I was under the impression that was one of the big benefits of the Pingel--completely rip-out both stock petcocks (tank and remote vacuum operated) and have one manual petcock at the tank, with one fuel line running to the carbs.

Now, I'm apparently flirting with disaster here has I've ripped out the second petcock, directly plumbed the fuel into my carbs from the prime outlet of the tank petcock, and just added a valved quick couple inline.  With how much I've had to take that tank on and off, the valved quick couple is wonderful.  (Too bad I broke down and bought after most of that work.)  I could add an inline valve, or if I wasn't so cheap, I'd spring for a Pingel.  (That and having to completely empty the tank again, file-out the hole to accept the Pingel petcock, etc.)

So, how long till I blow-up my engine by filling it with gasoline? 

-B.

(P.S. if I know I'm going to be sitting the bike for a while, like when it's been out of service, I do disconnect the quick coupler.)

Sadly that's nothing you can fix without buying another bike.  I think the odds are slim of disconnecting a fuel line in most accident scenarios that leave the fuel tank attached to the frame.  Certainly not as high as the odds of me forgetting to turn the valve off prime when I get to the office 20 minutes late.

Dgyver,

Thanks for the answer.  I am a newbie enough at working on my bike that I have to ask, where do I get a vacuum cap and what size will I need?

Thanks

Auto parts stores carry them. Not sure the exact size, but 3/32-1/8" should be fine. I believe they they can be purchased in a variety pack. In a crunch you can use plastic caps (typically used as thread protectors) found at hardware stores but they will become hard and may eventually crack.

Here's the Honda gas tap that we have been talking about - mine came in tonight at the dealers after I ordered it Wednesday evening.

and here it is next to the original Suzuki one.

There is a locating ridge on the rear of the Honda one that will need to be ground down for a good fit, and I found I will need some more fuel line as the stock length is now too short. The main feed line to the carbs exits at the rear of the Honda tap. The Honda one has a nice big handle to hold onto, bigger than the Suzuki one.

Is the position of the CRF petcock the same position that you install it in?
