1. GENERAL INFORMATION                                                            K-XCT 125i


 POOR PERFORMANCE AT LOW AND IDLE SPEED

                                                              Possible cause

1. Check ignition timing                        Incorrect    Improper ignition timing

   Correct


2. Inspect the fuel flow                        Abnormal     Faulty pressure regulator


   Normal


3. Inspect the fuel injector                    Abnormal     Faulty injector


   Normal


4. Check for leaks in the intake pipe            Leaking     Loose insulator clamp
                                                             Damage insulator

   No leak


5. Perform spark test          Weak or intermittent spark    Faulty the spark plug
                                                             Faulty carbon or wet fouled spark
                                                            plug
                                                             Faulty ECU
                                                             Faulty ignition coil
                                                             Faulty ignition pulse generator
                                                             Faulty ignition switch
                                                             Loose or disconnected spark plug
                                                            wires
   Good spark
