Does the engine stall or lose power when you accelerate? Several points must be checked in order to detect the fault.
Check the tank of fuel, if the fuel level is too low or if the tank is empty.
The checks to be carried out on your carburettor:
â†' Insufficient fuel flow.
â†' The carburettor setting (Air adjusting screw, the sprinklers).
â†' Air poor (check your air filter).
â†' Air-rich (check your admission).
â†' Throttle grip out of adjustment (check the bushel).
The checks to be carried out on your ignition:
→ The spark plug (loose or defective).
→ The CDI case works badly.
â†' Ignition sensor or theIgnition is defective.
