After driving for a year and a half, many motorcycles will find that the exhaust pipe is rusty, and they don’t know how to deal with it. They just have to wait for it to slowly decay and replace it with a new one, so they will naturally feel a little helpless. In fact, it can only be solved by doing a small maintenance every 3000-5000 kilometers (according to personal driving time).

The method is as follows:

Prepare a small oil gun, put the front of the car on a slope, use the oil gun to add a little oil from the tail end of the exhaust pipe. After starting for a moment, blow the accelerator a few times, so that the oil can evenly coat the inner wall of the exhaust pipe. The oil can not be excessive. A protective film can be formed.

Before operation, you need to know:

1. Before adding oil, make sure that the drain hole is unblocked, otherwise the hazard will be the sludge mixed with water vapor and high temperature oil in the exhaust, which is difficult to deal with.

2. The purpose of injecting oil into the exhaust pipe is to prevent the exhaust pipe from condensing some water and acid substances after chemical changes on the pipe wall after entering the exhaust pipe due to the high-temperature and high-pressure exhaust gas after the engine combustion, which will affect the life of the exhaust pipe. In order to protect the exhaust pipe and extend the service time, after the motorcycle has been running for a period of time, inject some oil into the exhaust pipe, but not too much, and the capacity can be controlled at 15ml-20ml.

It should be easy for motorcyclists to learn these minor maintenance knowledge, and they should be quick to get started. Only by knowing your car can it bring more driving pleasure.
