I had the same problem with my 550. I had fuel flowingout of the second carb overflow. The problem for my bike was a stuck needle valve. WhatI had to do was to take the bottom of the float assembly off, to take the float off and to spray some carb cleaner into the needle valve to get it not to stick. However, the problem was junk coming from the tank and clogging up the valve, so in ten minutes I had the same problem again.

What I did this time was to install a small in-line filter between the tank and the fuel intake for the carbs. It looks a bit wonky, but I've run it now for over a week without having the same problem flare up again.

from what I can find it is self adjusting......if you can hear it slapping then the self adjustment has run its limit and you have to replace the cam chain hope this helps

Could be a stuck needle and seat causing the engine to flood and die,in which case you will have to remove said carby and inspect . you could try tapping the float bowl to free up the float . Use medium taps with a length of wood,it's more of a shock and awe tactic . May work for awhile then it's back to square one.Goodluck ..PJ.

Contact points cover open.

Left side points are for cylinders 1 and 4.
Right side points are for cylinders 2 and 3

Left side points have a White wire coming from it.
Right side points have a Black wire coming from it.

One coil runs two cylinders.

One coil runs cylinders 1 and 4.
One coil runs cylinders 2 and 3.

No matter what style of ignition coil you use, the Black wire will connect to the Points. Whatever other color of wire they use, connects to the ignition switch.

BUT, check the specifications for the coils you're going to install. Connect the Negative side to the points. The Positive side to the ignition switch.

The Orange wire with a White stripe, coming out of the harness of the Suzuki Gs550 is from the ignition switch. It goes to a splice connector, and from there goes to two wires. The wires split off into one wire for each coil.

There is a White wire on the coil, that is used for Cylinders 1 and 4.
There is a Black wire on the coil, that is used for Cylinders 2 and 3.

The Haynes manual for the 1979 UK model GS550L states 217cc of 15W fork oil per leg.

When you reassembled the bike did you pinch any of the wiring harnesses? Trace the wiring through the bike and make sure everything has a solid connection between their respective power sources and activation switches. Alot of time bikes run wiring under the gas tanks so you need to make sure that you didnt cut anything when pputting it back on (if you removed the tank)

When they are farthest apart. They have to close, so there would be zero gap at the closest.

.014"-.016" is the point gap

my quad did the same....my valves(5) were way out of adjustment.I adjusted them(with a feeler gage) and now it runs pefectly

Need more info, is the batt good? Are the plugs wet? Is there spark?

clutch pushrod should just pull out as it should be a 2 piece clutch pushrod model, earlier models were 1 piece and you had to remove clutch cover and pressure plate to remove. hopefully the seal is ok.

After replacing all rubber and brass parts, set up the float height with the new needle valve.

need to adjust the cabke at both ends, as the pin to actuate seems like it is too far in, opperting the clucch, use the manual.

In cold weather is fine, but it seems a carburetor problem

In is lean out is rich, but these are low speed adjustment and will not cause your symptom.

is it the carbs with diaphrams on top ? check they seated correctly ! if slide type then renove filter and get a rag to block slightly the cyl thats off as you run engine and see if it starts to fire , if yes then see if it runs without rag acting as a choker ! if not then clean and rebalance the 4 carbs so they open at same time !
