Hi, James and the usual suspects are:
1. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
2. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
3. Spark plugs in bad condition or partially fouled.
4. Spark plug cables in bad condition and leaking.
5. Spark plug gap too close or too wide.
6. Faulty ignition coil, module, and or sensor.
7. Loose, dirty, or corroded ignition module connector at crankcase.
8. Faulty CKP or CMP, MAP, ETS, ATS, TPS, O2 sensor.
9. Intake air leak.
10. Water, dirt, or rust in the fuel system, carburetor and/or filter.
11. Fuel tank vent system plugged or carburetor vent line closed off.
12. Vacuum line from intake manifold to fuel valve is broken, cracked, pinched, or missing.
13. Carburetor controls misadjusted.
14. Damaged carburetor.
15. Incorrect valve timing.
16. Weak or broken valve springs.
17. Damaged intake or exhaust valve.

1982 gs650l with 1438 miles, I had the tank coated and now it doesn't get gas to the 4 carbs. It will run if you spray eather into the carbs.

Check that fuel is coming from the fuel pipe before the carbs.
If not , your fuel tap / filter may be blocked.

81 Suzuki gs650 #2 carb floods gas out after start

The float is stuck open in the leaking carb. Remove the float bowl and clean the carb after removing the pin holding the float in place. While the float is out, shake it to see if gas has gotten inside it. If so, you will need a new float or will need to drain the float then re-solder it to seal it up again. To drain the float chances are you will need to drill a vent hole in it to allow the gas to drain. Just solder the vent closed when done.

Where is the oil drain plug location on a 82 suzuki gs650L?

On the left side near the bottom of the casing. Be sure to install a new oil filter and to remove and clean the oil pressure switch.

I do not have a manual for my 1982 GS650L. Does

Sure it will. That's why it is there. Just fill the crankcase to the point it shows the oil covering 1/2 to 3/4 of the window. Yes, the case can hold more oil but don't add more thinking that would be better. The cylinder walls get lubricated by splash lubrication. Filling too full kills the splash and limits lubrication. Use 10w40 motor oil. Any major brand will do.

Please rate this solution! Thanks Briant! :)

Cleaning carbs on Suzuki GS650 L, what is the float setting?

to check the float height, invert the carb body holding the float arm pin so the pin will not slip off. With the float arm kept free, measure the height it should be 22.4 + or - 1.0mm
This is what the shop manual says.
basically what that means turn the float bowl upside down and keep the bottom of the float even with the edge of the bowl.
