Question about 1981 Suzuki GS 750 L

1 Answer

A friend has a 1981 Suzuki GS1000. He bought the bike after it had been parked for 7 years. I have cleaned and boiled the carburetors and blown them out with air. The slide diaphragms are in good shape. We can start the bike and have the idle set at 950 RPM. We can rev the engine up 3-4 times then it sounds like it is starving for fuel. Let it idle for 5 - 10 seconds and we can rev it up again 3-4 times and the problems repeats. we have pulled the carbs again and made sure the inlet needle valves are clear. we even have this problem when we use a gas can elevated with fuel line feeding fuel to carbs. Can you help figure this problem out?

I have a 1982 yamaha 650 seca turbo. I just bought it and was gone for two week on vacation. pon returning, my motocycle leaked gas from the exhaust pipes. So I cleaned my carb. Boiled it in lemon...


When the carburetors over flow enough to fill the exhaust, It is possible that the gas also went into the cylinder and flowed past the rings and into the crankcase. With the engine overly full of gas and oil you could easily pop a seal or blow out a gasket. Check your oil level. If it is too full , change the oil, it will not lubricate properly with all the gas in it. Check that your shaft seal has not popped out. Check the air filter, the breather may have blown oil and gas all over it when you started the bike. Empty your pollution tubes behind the motor( they will drain the air box). Get in the habit of turning your fuel petcock off when not riding. This gas flooding happens randomly in certain models but can happen to any one.

I have a 1981 suzuki gs 750 engine on a quad. i finally got it running but it runs poorly. i cleaned the carbs twice and put new spark plugs in it. its running on the two cyclinders that farthest away from...


Is the fuel tank located above the carburetors at about the same level as the original bike? If not, you may have to install an electric fuel pump to get the pressure at the carburetors about the same as the original bike (guessing about 1-1/2 to 3 PSI). I assume that you have checked things like firing order, timing, throttle slide balance, compression, and equivalent exhaust system. Did you see and hear the engine run before you installed it into the quad chassis? Hope some of this helps!

1981 550 suzuki one cyclinder is dead has spark and fuel and bike runs but start extremly hard seems cold blooded


Check compression of cylinders, all should be close the same. Swap spark plugs and check if problem cylinder moved. If bike sits for long periods of time then most likely it will be a plugged carburetor.

Will not stay running without enricher on


The carburetors need to be cleaned most likely clogged jets and passage ways.the low speed jet is what you want to pay close attention to make sure the are clean.
If you are going to do it yourself pay close attention do not mix up the carburetor parts always lay out the parts from each carb in the from left to right 1234 separation.
I suggest you get the service manual fir this bike before you attempt doing the work yourself.
