Hi guys, I have a problem with my Kymco agility 50, year 2007. The scooter reaches impressive high speeds, around 55-60 km/h, but at low speed, especially when starting, it gets speed pretty slow. I've recently changed the air filter and checked the spark plug, it is looking fine. Also, sometimes the throttle response is a bit laggy. Does anyone know what might be the problem? Thank you!!
