Hi, Anonymous and the usual suspects are:
1. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead-acid batteries.
2. Failed alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.
4. Failed main circuit breaker or ignition switch, check for loose connections and continuity.
5. Failed system and or ignition relay, check for continuity.
6. Failed ignition coil, stator, magneto, ignition/electronic module.
7. Failed CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Throttle cables and or idle speed improperly adjusted hot idle speed should be 950 RPM to 1000 RPM.
9. Faulty neutral, side stand or clutch lever safety switch.
10. Faulty or corroded kill switch.
11. Accelerator pump damaged or not working.
12. Water or dirt in the fuel system, carburetor or filter.
13. Restricted, blocked or kinked fuel line.
14. Fuel tank empty.
15. The gas cap is not venting properly or fuel tank venting system blocked, loosen gas cap and go for a test ride.
16. A failed fuel pump, pressure regulator and or fuel injectors.
17. Vacuum line from intake manifold to petcock broken, cracked, or not attached, carburetor vent line plugged.
18. Needle and seat stuck closed in the float bowl.
19. Petcock clogged or damaged.

Hi, Anonymous before testing any electrical component in the Starter Circuit it is "IMPERATIVE" that you have a fully charged battery of 12.5 volts or more and be able to pass a proper "LOAD" test because your battery may have 12.5 volts or more but little or zero amps causing the battery to be faulty and must be replaced, especially "AGM" batteries.
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Check the 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.
4. Bank angle sensor needs a reset or is faulty.
5. FOB battery low or dead.
6. Faulty ignition switch.
7. Faulty starter button.
8. Faulty kickstand or clutch pull in switch/sensor.
9. Security alarm needs a reset.
10. Starter relay, solenoid or starter circuit wiring faulty.
11. Starter armature or field coils have failed.
12. Main fuse or circuit breaker may be blown or faulty.
13. The electric starter is working but starter clutch has failed.
14. Check for engine trouble codes.

Hi, Henry after careful deliberation 4 out 5 Suzuki Gods give this one a thumbs up, but just to be on the safe side you should give your local dealer's parts/service department a call to confirm. Good luck and have a nice day.

As suggested, check the voltage with the engine running accross the battery. If its below 14 volts you have an issue with the stator windings/regulator/rectifier/wiring.
Do the cheapest thing first and clean up all electrical connections, esp the earths.
A manual will tell you how to test the charging system, but the Suzuki GS range has always had charging issues.
The simplist method is to fit the combined reg/rectifier unit from a Honda CB250/400 Superdream.
Always keep your engine oil topped to the max mark, as this cools the stator.
Dont leave this, it is not unknown for the entire system to fail including the CDI if left unchecked.

Hi Henry, I'm leaning towards weak battery or starter, do a proper load test on the battery and the starter circuit, for more information about your question please visit the website below. Good luck and have a nice day.

Do you know where it is located?
Have you had issues with it, as in dead and let to freeze, acid spilled out onto the bike from being frozen or overcharged etc?
If so mix up some baking soda and water and pour over connections and frame then wash off bike before swapping battery.
Take off negative first and put back on last, just like with a car battery.
If wet cell, fill to proper level and charge first on 1A or smaller charger for a day... If GSM or Gel, install and ride.

how long you letting it idle and not moving down the road ? its air cooled that needs movement to cool the engine ! another problem i once had was that after i polished the side casings to make it look good in a chopper style bike it overheated quicker than before , just a thought ! is yours std ? any more info you got ??

1980 Suzuki GS... | Answered on Apr 29, 2014


sounds like the clutch push rod is bent and the seal has more pressure on one side so leaking ! pull rod out and see if it can be straightened , if not then replace it and the seal !

1980 Suzuki GS... | Answered on Apr 29, 2014


This is a bit vague.. If engine is running an you select a gear but nothing.. I would look to the drive between the crank and gearbox.. this goes via the clutch and could be the issue..
This sounds dumb but check the obvious.. start at the back wheel and work back.. check chain and front sprocket.. then ensure you can select gears and then clutch and primary drive..

1980 Suzuki GS... | Answered on Apr 28, 2014


Have you looked inside the clutch case ? check the clutch is releasing , check the keyway on the crank cog hasnt snapped that drives the clutch etc !

1980 Suzuki GS... | Answered on Apr 27, 2014


Any modifications to the air box will cause mixture changes. You may need to re jet the carburetors to compensate.

1980 Suzuki GS... | Answered on Apr 13, 2014


Sticking or badly adjusted float valve in one or more of the carbs...be careful when turning it over until sorted as may cause hydraulic lock.
