Hello guys, Have Kymco Agility E4 BJ.2018 50cc LC2U010B1…. Engine number: KN10A1011265 Is with the Dellorto E4 carburetor. Running power 2110 Km I have the following problem: During the drive when you turn up the gas like a jerk it starts to stutter strongly and then just does not drive anymore no matter how long you hold the gas then, only after you let it go and slowly give gas it drives again, it feels like a speed limiter attacks like with the 25kmh scooter with electronically throttled CDI. I have somehow suspected the ECU, maybe someone has experience how such an ECU behaves when she has one away. The error lamp does not blink on even after longer driving. I have tried the following. Switched: petrol, petrol filter, air filter, spark plug, jerks and sliding shoes 6.5 grams, belts original Cleaned: carburetor, air filter box, filter of the solenoid. Submitted: valve game Tested: petrol valve, compression 11 bar, whether slurry If they are free, converters are tested, ignition coils are measured on testers and ignition lines. Had it read out again, error codes are not stored and values are inconspicuous, Poti from the carburetor reacts immediately when measuring. Furthermore, I have already noticed that there is extra software and adapters from Dellorto, does anyone know where to get them? No customer at the clutch is reading the speed from the pick up.
