Question 1

CDI unit / ignition control module failure

Accepted Answer

The capacitive discharge ignition (CDI) unit on this model can fail intermittently or completely, causing hard starting, misfiring, power loss or sudden engine cut-outs, particularly in hot weather or after prolonged use.

Question 2

CVT belt and variator wear

Accepted Answer

The continuously variable transmission (CVT) belt stretches and the variator rollers wear over time, leading to sluggish acceleration, belt slip, abnormal whirring noises and reduced top speed on this scooter.

Question 3

Carburettor flooding and jet blockage

Accepted Answer

The carburettor on the 124cc engine can develop stale-fuel deposits blocking the main jet or pilot jet, causing hard starting, rich running, black smoke, or conversely lean hesitation. The float needle valve can also wear, leading to fuel overflow.

Question 4

Stator / ACG charging coil failure

Accepted Answer

The stator (ACG) coils that charge the battery and power the lighting system can short or open-circuit, resulting in a weak or dead battery, dim headlights and intermittent electrical supply while riding.

Question 5

Kick starter mechanism jam or spring breakage

Accepted Answer

The kick starter ratchet mechanism or its return spring can fail, making the kick starter ineffective or causing a grinding noise when operated. This does not affect the electric starter but leaves the rider without a backup starting method.
