Many people don't know how often the motorcycle Spark cap needs to be replaced. In fact, it is usually replaced every 20,000 kilometers.

1. Motorcycle Spark cap is commonly known as fire mouth. The function of the spark cap is to discharge the pulsed high-voltage electricity sent by the high-voltage wire burner line, break down the air between the two electrodes of the spark cap, and generate an electric spark to ignite the mixed gas in the cylinder. The main parts of motorcycle Spark cap are insulator, housing, terminal screw and electrode. The insulator must have good insulation and thermal conductivity.
2. There are many kinds of motorcycles, and the positions of different motorcycle Spark caps are different, but they are all installed on the cylinder head of the top vertical cylinder machine or the most front horizontal cylinder machine, but some are on the right side and some are on the right side. On the left side, some are on the top, and some are on the left side. Look at the thick line on the cylinder head is the high-voltage line, and the high-voltage cap is connected to it. You can see the spark cap when you remove the high-voltage cap.
3. Ordinary nickel alloy spark caps are the most loaded, and the mileage is about 30,000 kilometers. The platinum spark cap can greatly improve the service life of the motorcycle Spark cap. The replacement mileage is about 60,000 kilometers. The iridium spark cap has better metal and better electrical conductivity, and can produce stronger and more stable sparks. The replacement mileage is about 80,000 kilometers.
