Your carburetors need a good cleaning. Specifically the slow circuit ( slow jet and passageways ) are plugged with dirt or corrosion. You should take the carbs off, disassemble them, and clean/spray carb cleaner and compressed air through the jets and carb body. If you remove mixture screws , be sure you count the turns and write it down before you remove them so you can put them back in the same positions when you reassemble. Install new spark plugs and spark plug caps and your bike should run like new.

Engine revs out of control

check the inlet rubbers between the carbs and engine for cracks or hardening as an air leak here could be the source of your problems...

Can you use a lock set from a 1980 gs 750 on a 1981 gs 750

seat lock yes, ignition lock if it fits in the hole ,you'll have to get a wiring diagram on line and match the wires by what they operate,if your really lucky wires run the same stuff and are the same color.

Hi and welcome to FixYa,

Almost always, your described problem would be the float needle not closing the inlet seat. This could be caused by a dirt, sand, contaminant, worn needle ends, grooves on the seat. Unfortunately, the only fix would be to pull down the carbs again and redo. Considerations are:
  • ensure the pointed end of the float needle are not nicked, worn, necked, scratch;
  • ensure that the inlet seat are perfectly round and smooth. You may need a very very fine abrasive material and a Q-tip or cotton buds and do a bit of lapping ( almost similar to valve grinding);
  • ensure the float height is correctly adjusted;
  • verify float is not punctured with fuel sloshing inside.

Good luck and thank you for using FixYa.
