Thanks for the input folks. I’m adding the photos Marcel requested in case the numbers on the flywheel aren’t legible (no sign of damage btw) after the direction arrow is YS and below that is 32102HR86. The sticker on the cpu is unreadable so I hope you’re able to distinguish it by visual. The sensor doesn’t have any markings nor does the stator. I hope this helps.

Cpu Hi Jan.
2 things to check.
1: Throttle position sensor. I’m not familiar with the system for GT650i so you would need to Google it.
2: Throttle body butterflies. To check that both are operating properly you have to remove the tank and airbox and see if the butterfly valves are moving the same amount. This may sound confusing but once you have the airbox off it should become clear. If one is not opening and closing freely then check for damage or carbon build-up.
Afraid I don’t have any other suggestions so I hope this helps.
Hi Jan. If you look at what moves on the engine when you twist the throttle where the cable is attached should rotate on both sides of the engine. If both move then cable is ok. If only one side moves then cable is most likely snapped. You described twisting throttle hard and if cable was badly adjusted then it can fail.
This sounds awfully like one of the throttle cables has snapped. Check both bodies are moving when you twist the throttle. It would throw a F1 fault. If it’s cable it likely won’t rev above 4000 in neutral.
Recently saw this whilst looking for something else. I have got parts from them before ( swingarm and exhaust ) found think very good. They are based in Spain so not sure about import duty for UK. https://www.motorecambiosvferrer.es/cerraduras-de-contacto/juego-cerraduras-moto-hyonsung-comet-gt-05-10862.html
If you raise and support the bike with the rear wheel off the ground and try to move the swinger arm left to right. If there is movement then the roller bearings need replacing. If no movement on swingarm try twisting rear wheel. If there is movement then the problem is likely to be either worn bearings or more likely worn cush drive rubbers.
