Scooter stalled during a ride, wouldn’t start back up.
Had been running great.
Two engine codes flashing: ignition circuit abnormal (been flashing for a couple yrs, scoot running fine so I ignored it)
Oxygen sensor circuit abnormal (just started)
Replaced the o2 sensor about 8000 miles ago. Time for a new one? First one lasted almost 30,000 miles, replacement was oem.
Search revealed CDI box, stator, or ignition coil could also be the issue. How to find out which?
Can start by replacing o2 sensor, but at $130 it can be a pricey process of elimination
