kymco x-town 300i problems with starting idle and CVT checks

kymco x-town 300i problems forum question

I am collecting kymco x-town 300i problems from a scooter that starts cold, idles a little rough and feels lazy when pulling away. I want a checklist before random parts.

I found this related page while comparing notes: kymco x-town 300i problems. I wanted a practical thread before guessing.

Would you check battery voltage, charging output, stored codes, air filter, plug, fuel quality, throttle body, belt width, rollers, clutch dust, brake drag and tire pressure first?
