Gs1000g having trouble finding the correct size fuel valve pet cock.

I ordered a petcock that was labeled for a gs 1000g and it does not fit, the bolt holes are not wide enough. (Not to mention they want to charge me half the cost of the part to return it) Searching online there are several different ones labeled for my bike, but all look different sizes. It would be nice if I could find a replacement that has a lever instead of the free spinning screw. Anyone know of any?
 
I'm a little frustrated right now. I wish the companies would give spacing measurements.
 
OK, a little clarification might be necessary. What year GS1000G, and is it in fact a G or might it be a GL?

The reason I ask is that the 1980 1000GL has a screw-looking selector in the petcock, but the 1000G does not.

I wonder if it is a gl then. As far as I know it is an 80 I hate the screw pet cock. I wonder if it was identified wrong. Also any information you have on the air needle adustment valve and the turn nob (drawing a blank on name at the moment) on the bottom of the carbs would be awesome. Not sure how many turns they should be at.

All my other bikes were easy to identify and find parts for. This one has me feeling dumb.

Are there side covers on the bike? If there are, they should say "GS1000G" or "GS1000L".

If you don't have side covers, look at the VIN plate on the steering stem. That will show the exact model, right after the serial number.

There are also a few other obvious clues that are visible from 20 feet away.
1. Front axle. Is it under the ends of the fork tubes or in front of them?
2. Front fender. Is it painted or chrome?
3. Headlight. Is it a 7" light in a black bucket or a 6 1/2" light in a chrome bucket?
4. Instrument panel. Is it a large oval that contains the speedo, tach and other lights or are the speedo and tach separate?
5. Fuel tank. It is large, somewhat rectangular with beveled edges, or is it a smaller "peanut" tank?
6. Handlebars. Are they a modest rise and somewhat comfortable or are they high and very awkward on the wrists?
7. Seat. Is it long, wide, flat and very comfortable or is it stepped, considerably narrower and rather uncomfortable?
8. Rear fender. Is it black plastic and under a body-colored tail section or is it chrome?
9. Tail light. Is it rectangular and under a body-colored tail section or is it standing alone on a chrome fender?
10. Mufflers (if stock). Are they almost long enough to reach the back of the tire or are they barely long enough to reach the axle?

In all 10 of the above questions, the first half will identify your bike as a G, the second half will identify it as a GL.

There are many things that can be done to "de-L" a bike, usually in the name of ergonomics, which will remove one or more of the 10 identifiers listed above, but almost never will anyone intentionally add one of those 10 to make it more like an L.

Measure the centerline spacing of the original petcock mounting bolts...is it 50mm or 44mm....these are the most common.

Side covers were
Spray painted so not sure
Vin says gs1000g-
In front of axle
Fenders are both chrome
6.5 chrome headlight
Tach and sped seperate
I guess kind of a peanut shape for the tank
Seat is stepped
Handle bars have about a 9 inch rise from the bottom
Tail light stand alone on top of the chrome
Mufflers go right up the the rear axle
 
8 out of 10 say you have a 1980 GS1000GL. Not a bad bike, overall, just that it has a few items that are somewhat unique.
Fortunately, that particular package of unique features only lasted for that one model year.

Going back to your original quest of finding a petcock, your best source will be Suzuki. One of our favorite vendors is Parts Outlaw. The unfortunate part of that is that the part will cost you $83.67, and another $4.99 for shipping (if you enter the discount code listed at the top of every one of their web pages), and it will take about two weeks to get to you. Beyond that, you will have the assurance that it is the proper item from the original manufacturer and will last another 25 years or so.

Hey thanks for the info. Do you know if there are any generic cheap versions out there that will fit? Im not entirely sure the one I have is bad, I just cant tell becuase I am having trouble getting it started. Even with rebuild carbs and manually feeding gas into the line
 
Several have had at least a modest success with an eBay seller GeorgeFix or something like that. Not sure how much (if any) cheaper that might be, but you do have the assurance that the Suzuki unit WILL fit and work properly.

I had purchased a replacement vacuum style petcock. It didn't last very long. Can't blame anyone but me on this one LOL... So, I changed my mind and went with an old style petcock. Adapter plates are available and the tank needs to be massaged where the filter goes through. The replacement is round as opposed to oval.
I prefer this style. Not all will. And for what I'm building, I need the flow :-)
