Gv 250 efi 2013 one cylinder problem

[Hakan]

Hello everyone, I am a gv 250 efi user living in Turkey. I joined here for a problem that I have not been able to solve for a while. The problem I am experiencing is that my engine is running on one cylinder at low speeds but when I accelerate it becomes normal. The spark plugs have been changed, I do not know where else to look. I am waiting for suggestions from friends who have experienced the same problem or know the situation, thank you.ps my Bike at 45000 km and dont give fault code so i dont know where should i look. have a nice rides
