Symptoms of a broken motorcycle Spark cap include severe carbon deposition, engine bumping, increased wear and tear, and difficulty in starting.

If the motorcycle Spark cap is broken, it will not be able to speed up at first, and sometimes it will shoot. If it breaks in the middle, you can choose to start the fire, that is to say, you can remove the high-voltage cap and tie the high-voltage wire to the heat sink, 1-2 mm away from the spark cap, so that the car can be used for a meeting and replaced with a new one. The working environment of the spark cap is high temperature and high pressure. After a period of use, part of the electrode will burn out, the gap between the electrodes will become larger, the electrode will be oxidized, and the life of the motorcycle Spark cap will be shortened until it cannot flash over and be scrapped. The spark cap of a motorcycle can also be detected by fuel consumption. Motorcycles are getting more and more fuel-hungry and don't ride as smoothly as they used to. If there is any power phenomenon during acceleration, consider replacing the spark cap when there is a similar situation.
When the car is driving in a certain speed range, the engine "shakes the car" phenomenon. Accelerating at this time, the engine power is stagnant, and the running power is obviously insufficient. With the increase of fuel consumption, even the exhaust gas or black smoke, indicating that the performance of the spark cap is significantly reduced. Too much carbon deposits on the spark cap, too much precipitation material, the gap of the spark cap becomes larger, and the ignition energy is insufficient, which will cause difficulty in starting. A damaged motorcycle Spark cap will also cause the exhaust gas to exceed the standard and the spark cap to fail, resulting in the ignition system not working properly, the mixture is not fully burned, and some harmful substances cannot be fully burned before being discharged. Generally speaking, when the motorcycle Spark cap ignites, the spark is blue, but if it is inconsistent with this color, it means that the spark cap is damaged and needs to be replaced. When the color of the spark cap is yellow-brown, its performance is the most normal, which means that the engine combustion is the best at this time, and the fuel consumption of the vehicle is also the smallest.
A damaged motorcycle Spark cap will affect the normal use of the motorcycle, so you must go to the repair shop to check and repair or replace the spark cap immediately.
