Sorry to hear about your carb issues. Two possible issues that come to mind are (1) fuel level in the bowl most float assemblies are made of brass and have a small tab which applies pressure on the float needle. If this tab is not adjusted correctly the fuel will not shut off when the float reaches its maximum height. The tab can be bent to apply pressure at just the right moment. You can verify this by doing a bench test, with the bowl off. So much nicer to know before going through all the work of putting it back on the bike. (2) Check the buoyancy of the float itself many of the old-school foam ones dont have enough umph to close the needle all the way. If you have the brass style floats make sure you dont have a leak. ( submerge the float then check for air bubbles also shake the float and listen for gasoline within) Check with GDL Cycles they can help you with those hard to find parts for many old school Japanese bikes.

HI zizi_tripo,

Sounds like a familiar problem to me. I've bought a GS550L from '85 for my daughter a couple of years ago and had the same problem. This is caused by O-rings not sealing off. I can't exactly remember which ones, but it has to do with the floater mechanism. As soon as the fuel chambers of the carburetors are filling, the floaters go up and close the fuel supply. If the they don't, gravity will keep on drawing full out of the tank and the carburator will start leaking, mainly through the air inlet/filter housing.
I solved the problem (after a lot of searching for it's origin) by buying two simple O-rings (€ 1,00 each) and replace the old ones.

I just bought a 1982 GS550L Suzuki. It seems like a float in one of my carbs is stuck; the gas spills over and the engine randomly revs when it sits and idols. I tried to take the carburetor off to clean...

There is no special trick for easily removing these carbs from your GS550L, though it helps if you did well in high school geometry--you can use that knowledge to help you figure out how to angle the rack of carbs to get them in and out of the frame. The basic steps of the procedure are very simple: remove the throttle cables (can't remember if this bike as a single or dual cable system), loosen the clamps holding the carbs to the flexible collars connecting them to the motor and to the air box, and then wiggle the carbs free. Sounds easy, right?

Your first problem will be getting the carbs free from the rubber collars in which they've been mounted for years--possibly since 1982. They'll be glued in place, but you should be able to get them free--one at a time--with some judicious force. Because there's not a lot of wiggle room in there, you'll probably want to remove the air box and battery so that you have a bit more working room. Even then, prepare to leave some skin on exposed frame welds. My experience has been that it's somewhat easier to pull the carbs back away from the motor and then disconnect them from the air box, if you weren't already able to disconnect them when you pulled the air box to create more working room. The carbs are mounted in a rack. Once they're free, you should be able to angle them slightly and pull them out of the bike frame.
Believe it or not, it may be harder to get the carbs back in place than it was getting them out. If you have the money, you might want to consider getting a fresh set of rubber collars to connect the carbs to the motor. The old collars will be stiff, hard, and likely to crack when you try to set the carbs back into them. If you get new intake collars, you might be able to fit them onto the carbs before you slide the rack back into place; you'll then just bolt the new rubber to the motor. Or, if the mounting bolts will be inaccessible, go ahead and mount the collars to the motor first. I have found that lubricating the rubber with some soapy water or KY jelly will help the carbs slip into place a lot easier. Both of these lubricants will naturally dry, and they won't damage the rubber parts, either.

Good luck with your project!

My 1982 Honda v45 will not run without the choke on. It sat in the garage for years with old fuel in the tank. We drained the fuel, changed all the oils, etc and completely REBUILT all 4 carburetors. I...

The slow jets and adjoining passageways are still dirty. As painful as it may be , take the carbs off and clean the slow circuit again or it will never idle. Double check the fuel pump is working properly and the fuel filter is not plugged. One time it took me four cleanings to get all four carbs working on a Suzuki that sat for five years. Also make sure none of the carburetor boots have developed rips from age.

Suzuki gs550l flot height

not sure on the exact specs but flip the carb upside down and look how the floats look to the horizon of the earth. Sounds silly but that is how pretty much all bike mechanics set them, just make them level to the earth. Good luck

Leaks gas

the needle and seat in the carb isn't seating. First, shut off the petcock, and drain the fuel bowls with the screw on the bottom of the bowls. Let all the gas drain out of the bowls.Tap lightly on the carb with a small hammer, the refill the carbs, see if it still leaks. if it does, you need to pull the bowls off, remove the float and clean out the needle and seat, and put it back together
