I must of owned over 15 suzukis in the last three years since I started this hobby. Now most of them from memory , did leak gas or just spill it on the ground if the petcock didn't have a shut off valve. I have run across some old Kaws that did it too. I have a Gs I tore down at least ten times this weekend too get the third carb too work. Which it is finally now working. But I noticed a puddle of gas this morning where there wasnt one before.

Not on prim but reserve.

Ok what causes this too happen. I know it goes away on its own sometimes. I don't see it usally happening when its running. So explain too me what causes that too happen too these older bikes. Is it the bleeder screw? Can't be the float height. Those are set too standard settings. 24 mm. Bad gas?? I do know this one tank did at one time have rust in her.

Bad float needle and seat, bad o-rings in the connecting Ts, leaky petcock. That should about cover it.

that must be why on these older bikes I see alot of shutoff valves then. That does make sense. It usally goes into the overflow tubes and onto the ground. I seen alot of the gs's over the years with shut off valves too the petcock.

Thanks.

It is most often the vaccum diaphragm in the petcock that fails in the GS's. You must know what I am taking about Cyg? The petcock is vaccum operated, that is, there is a small vaccum line that attaches to the intake manifold (or output manifold on the carbs). The diaphragm fails, and gas leaks directly down the vaccum line in front of the carbs where it pools up and eventually leaks into the airbox.

A Pingle fuel tap is a good upgrade. If you use a common shut off valve, make sure the valve is no smaller than 5/16" ID.
