What Causes No Spark When Starting a Motorcycle?
1 Answers
Motorcycle starting with no spark is mainly due to incorrect ignition timing, cylinder scoring, or demagnetization of the motor flywheel magnet. Incorrect ignition timing: For a motorcycle engine to start normally, it requires a strong spark and precise ignition timing. Cylinder scoring: Engine compression can easily lead to cylinder scoring during use. If the cylinder block is scored, engine compression will decrease. If the engine compression is lower than the motorcycle's requirement, it will fail to start normally. Demagnetization of the motor flywheel magnet: Most motorcycle engine generator magnetic fields consist of two or more sub-magnetic fields. However, when the magnet becomes demagnetized, the magnetic field strength of each sub-magnetic field varies, causing asymmetry in adjacent magnetic field strengths and resulting in significant current fluctuations.
