yes and you can also let a vac line slowly suck it up to do a even better job, but pleas read the directions, as you can hydro lock it fast if you not carfull. be really for a lot of smoke.

run the engine till it hot
run with the seafoam being sucked in
when you start to see smoke shut it off (after removing the can from the vac line) for about 5 min
then start and drive or rev it to clear it out, driving it is cooler

it can folw plugs so be ready to replace one if the idle gets ruff, and change the oil as well as there is a lot of corbon loose now.

Getting ready to try this... How do you get it to suck up the seafoam? GS is gravity fed, I didn't think there was enough vacuum to suck fuel out of a container of seafoam, unless I find a tiny funnel or something.

There's plenty of vacuum to suck out a bit of cleaner.  The problem is keeping it from sucking out too much.  I'd get some aquarium line, an aquarium valve.  That way, you can open and close the valve to regulate the flow.  You could even get a T and have both cylinders sucking seafoam at the same time.

Where are you talking about hooking a line up to? I was thinking of just sticking the fuel hose into seafoam instead of the gas tank, in which case I can't see how you would regulate it since if you don't flow enough, the engine is going to die. Sounds like maybe it needs to be hooked up somehow to flow along with the gas, but not too much? If so does this work any differently than just adding it to the gas tank?

Some googling indicates that some people say just feeding the engine straight seafoam until it stalls can cause hydrolocking, but other people say seafoam is combustible and has no water, so hydrolocking isn't possible. So I'm not sure what the heck I'm supposed to do other than add it to the gas tank...

The engine won't run on seafoam alone.  You have to hook it to a vacuum line.

Right, but other than the fuel lines where is there vacuum line on the bike? Or can I just hook the aquarium line up to the vacuum ports on the carbs and stick the ends into the seafoam? The directions also say to add around 1/3 of the can and then dump in enough to kill the engine, but I'm not sure if that's a good idea or if it's even possible using a small line...

Yeah, use the vacuum take-off ports on top of the carbs.  Believe me, you'll easily be able to pass enough to kill the engine.

Got it, thanks. We'll see if I can avoid a visit from the fire department down the road tonight

You can get sea foam in a aerosol can too, it makes it easier to squirt directly into the carbs. I think it has adifferent name but the labels look the same and they're sold side by side most of the time.

As far as the dieseil kerosene jet fuel military fuel debate; they are all slightly different. Kerosene and jet fuel (jet-A) I think are almost identical except that the jet fuel has tighter quality controll. Anything that can run on diesel will run on jet fuel or kerosene and most of the things that are supposed to run on kerosene or jet fuel (like heaters and jets) will work on diesel except that diesel is dirtier and has more sulfur so it'll smoke more and do more fouling. Hell, diesels aren't that picky, you can pour in old fryer oil in there, that's basically what bio-diesel is.

On a side note, I have heard of some diesel motorcycles in development.

I don't know how it compares to kerosene and jet fuel, but the new US standard for diesel fuel has much less sulfur. 

So in a nutshell

Which seafoam? The Spray or the tank additive? TO CLEAN A GUNKED CARB.
And how much of the additive do you add to a full tank of a GS500

I read the whole thread and it just seemed like one big kerosene rant..

Seafoam is a tank additive.

Read the can for instructions as to how much to add.

OR? You can just tell me how much you poured in to how much gas was in your tank, Because all it says is 1 pint serves up to 8 gallons. now If i did the division that would be very little! Anyways what about trying the vacumm line way. Does that work better or more effecient maybe?

I had an indeterminite amount of gas in the tank (between 1 and 3 gallons), and I dumped in a glug or two of seafoam.   Waaaay too concentrated, but beyond that I don't have any kind of measurement to give you.  Sorry!

If I'm not mistaken, the vacuum line method cleans the intake valves, etc.  It definitely won't clean the carb jets.  It doesn't get down there.

I've used Seadoam to clear up carbs on an old Goldwing I had. Found a site that had a method for cleaning carbs without removing them from the bike. It works well as long as the carbs are only partially blocked. If the bike sits long enough for the passages to get completely blocked nothing short of disassembly will work.
Basically, you drain the carbs, then add a mixture of 25% Seafoam, 75% Gas to the carbs. Disconnect the spark plugs, and run the starter for 5 seconds or so. Let the bike sit for at least half an hour, longer if it's been sitting for a couple of years. Then hook the fuel line back up and start it. Make sure you're outside, because the bike will smoke like crazy and stink like he!! for a minute or two till the mixture gets burned off. Repeat if necessary.

For normal use, just throw half a can or so into a full tank. That should help a lot if you live in the great white north, and forgot to winterize your bike.

I use a half can to a full tank of gas   Stinks like hell for a couple of miles, but after that it runs like a dream

I've read 1 ounce per gallon of gas, so call it 4-5 ounces for a full tank. You can put more in but it will probably smoke for the next 200 miles

Yeah it will   But the shaZam! is almost magic

Of course, in the time it's taken to talk about seafoam, you could have torn down your carb, cleaned it out, gave it a good polish, chromed it, covered its woo-hoo in gold due to an unfortunate smelting accident, and had it put back in.

Whoa!!!!!  Your carb has a WooHoo   You might want to check into that, I dont think thats normal
