Don't cut the fuel pick up screens leave them stock length so you can still have a reserve.
To do the mod
1) Remove the petcock
2) Take petcock apart
3) Clean filters
4) Remove small set screw that holds fuel selector in
5) Remove selector, being careful not to loose the spring behind it
6) with the long tab & arrow facing down, mark the existing channel to the left another 1/4 turn (should allow selector to spin to the right from "ON" to fuel
7) Grind out the marked channel with a dremel to match the existing set screw channel until the selector with the set screw in will turn to "Fuel"
8) use carb cleaner or berrymans to get all shavings off and reinstall it.
Once the selector is on "Fuel it will flow both the regular & reserve pick ups
You can use the fuel selector as, on (1 long pick up), reserve (1 short pick up), or Fuel which is both on & reserve at the same time.

One of the easiest mods to do. Literally takes about 15 minutes.
-
Good to hear
-
Thanks guy's, I took it apart and see what your saying.
-
You will run from the "Fuel" position. Just use a dremel to grind the stop out from the metal lever. Do not mess with the plastic barrel inside.
-
You have to take it apart. Once it apart you will see a stop that wount let it go past and on position you have to get rid of t he stop so you can turn it a 1/4 turn past the on position. So when its done the new on will be a 1/2 turn from the off
-
Yes it can be modded to feed off both tubes instead of just 1. You will lose your reserve but it flows twice as much. It requires some grinding on the petcock with a dremal, and making both filter tubes the same length. Somone might have a pic of the mod, I don't.
when you do this, do you turn the petcock to the on position and drill out the plastic closing the fuel off? Will this make it impossible to shut the fuel off? If someone can give a clear description on how to do the petcock mod it would be greatly appreciated.

A little 1211 wont hurt to seal it up
-
I did not. I just cleaned it up good and let it dry. I will do that on the new one that I already have coming.
-
did you put any dielectric grease on it to help seal o ring, just rub it on o ring and put it back on
-
Well I ordered a new OEM petcock earlier this week. Seems mine wouldn't seal to the gas tank after I removed it. It had a slow leak around it and you can't buy just the oblong seal. :'(
-
oh and you have to frim fuel tank for it to fit, all you do is cut the center out with a razor blade.
you can get just about any one you like, but you will need the adapter plate if does not have the 2 screw holes.
-
yep they will fit, there are a few different styles of the valve, you just have to look.
or buy the one i sent you. ;)
-
The banshee one has 2 outlets so ill avoid that one. So the bolt holes going into the tank are all universal?

i think its the banshee one, just look for the one that looks like yours oem one.
-
You will want the one with the single outlet unless you have twin carbs.
-
Are they all the same or is there a specific one for the lt tanks?
-
Pingle Guzzler is the one most were using. Not sure how much more it flows than a modded stocker.
-
Which pingle do most people use? Is a pingle better than the mod stock peacock? Both of my petcocks have the mod done but I've always wondered if pingle is better or not.
-
Some quads with modified engines and large carbs or guys running alky need the mod to supply the carb bowl with enough fuel, without using a pump.
A stockish Zilla on gas will be fine on the standard petcock. Just make sure the filters are clean and your gas cap does not restrict airflow into the tank.

Mod?
-
when you do the petcock mod you cut the long tube to the same size as the short one.
-
If you need to replace the internal o-ring, I have had good luck with a P16 15.8 x 2.4mm nitrile o-ring. That will stop fuel from leaking out of the valve around the selector. I have never had problems with the petcock to tank o-ring.
-
Yea its one of them parts you have to buy the whole unit. Just like the oring that goes in the brass piece in the carb. You have to buy the whole piece with that part to. Kind of bull poop they do that.
-
OK so I couldn't find this information anywhere on the site. I removed my petcock today and ran a new fuel line removing an inline fuel filter the previous owner had installed.
The Petcock has two tubes (main and reserve I guess) and both have filters on them (White parts in the picture). I was going to replace the oring but it looked ok. Also I don't find one listed on the Suzuki OEM parts finder but suppose I could find one similar elsewhere.
Here is a picture.
