Motor oil
This oil is the first place in maintenance, how to choose the right oil. Can refer to the following: multi-cylinder, high speed, must use imported semi-synthetic engine oil, preferably with fully synthetic imported motor oil. But don't add so-called additives for psoriasis. Wind oil cold cars have higher requirements for oil than water cooled vehicles. For some single-cylinder large-displacement vehicles, because the crankshaft is made of crankshaft bearings, the requirements for oil are relatively low, and semi-synthetic or SG-class genuine brand oil can be used.
Remember: oil is not a god oil. However, synthetic motor oil can be replaced by a longer number of kilometers, which is more cost-effective. Pure synthesis generally 3000-4000 km can be replaced, no waste, but also organic filtration, if your car is a large trade, regular replacement of the same brand of oil, then the engine should be very clean, no need to replace the oil filter, change two The secondary oil can be replaced by a machine filter. If you want to use 300V next time with 7100, then the filter will be replaced together (because there will be residual oil in the filter, do not mix different brands of different specifications)
2. Air filter
Air filter is the lung of an athlete for a good car. Therefore, the use of clean air filtration is a must. The air filter of the imported car is more expensive, a few hundred. Some riders have heard that it is so expensive, they think, or do not change.
But this is not the case, the air filter is damaged, the dust, the sand will all enter the cylinder through the carburetor [the same as the electric spray], the wear ring and the valve, if it is blocked, the intake will be poor and the combustion will be incomplete. Engine efficiency is low, power is insufficient, and fuel consumption increases. Increased fuel consumption may result in high exhaust fumes. After a long period of gas accumulation, the durability of the car, the power will be discounted. Especially in cities with poor air quality in the north, air filtration has to be cleaned every few months.
3. Tires
For tires, large displacement locomotives should not buy second-hand or domestic tires cheaply. Second-hand tires have been used for a while, and may have been placed for several years. The resulting rubber aging problem is very serious. The tires may look quite deep, but the grip performance has dropped very badly.
Those tires that are too shallow or have been engraved should not be considered. Now Taobao is so developed (I was still advertised in Taobao’s lobbyist article yesterday. I’m going to go, Taobao’s website does not need a small series of advertisements.) It’s best to buy new tires. The tire, a piece of more than a thousand pieces, and your car price is also a fraction of a thousand, but the tire as the only choice when the motorcycle is in contact with the ground when riding, it is very very expensive to spend more on the tire Wise choice! Domestically made to sell a few large factory tires to run the street is also okay.
Daily tire maintenance: clean and keep the tread clean, do not plug the stone in the pattern, the most important thing is that the tire can not be filled with water wax or oil, because the oil has affinity for the rubber, it will cause the tire to crack and deteriorate, harming itself Safety, because the motorcycle is bent by the pressure, the tire is the most important part of the car.
4. Carburetor
Same as above, the carburetor has been used for a long time, and some impurities will be accumulated inside. The oil drain screw under the carburetor can be loosened to make the impurities flow off with the gasoline. If the carburetor leaks oil, it must be repaired and replaced in time. Because some car carburetors are not designed properly, once the carburetor leaks oil, the gasoline will leak into the tank. If it is pushed, the gasoline will leak into the tank. Dilute the oil. If you have a large amount of gasoline leaking, you like to pull high, then your car is not far from hanging. This is why the basic carburet has a common car called the garbage truck.
5. Battery
If you ride normally, the battery does not need to be deliberately maintained, but if you don't ride in winter, remember to take the battery off and the whole car is powered off. It’s okay not to take it down, at least one or two weeks to make a hot car, let the circuit and the oil circuit run, of course, it is better to go out and yo.
Tips: Turn off the headlights before each time you hit the car. It’s a big deal for the battery.
6. Clutch
I can guarantee that even a 250-displacement car is enough to meet the daily speed. You dare to turn the oil. As long as the gear is not red, the basic car is still in normal use. But if you have a bad habit of half-clamping, then the car wears out. The record I have seen is that a dude completely opened the clutch piece of a 400CC sports car in the afternoon. The pieces of the clutch piece are mechanically worn and need to pay attention to this bad habit. I think that the half-pulling clutch was handed down in the era of playing 2 rushing cars. It is a kind of opening method for playing 2 rushing cars, but it is not suitable for high-power multi-cylinder cars.
7. Valve
This is amazing, how to maintain the valve? The answer is yes, the fuel additive sold at the gas station, a small bottle, red liquid, can add 40 liters of gasoline. I have tried adding a CB400. Before the airway was brown, the carburetor was disassembled after use. The entire airway was silvery white. Bright as new. Generally, you can take one maintenance routine for one year.
8. Spark plug and ignition wire
If you ride a large domestic platoon, you will find that it will be difficult to start after the rain. How to improve it? If you have a budget, it is necessary to invest in several modified high-voltage lines and a set of sheet metal spark plugs, including many customers. The official second-hand waterwheels are old ones, so high-voltage line leakage is very common, how common is it?
Can you see if the high-voltage line has hardened? Is the long-term high voltage hitting the part of the car body, is there a slight arc when driving? If so, then this sometimes excuses for spending money, if you have a big budget, , a set of NGK, and other imported high-voltage lines is indispensable, if you like the price, then a set of domestically-made force cool line is enough. Coupled with the cooperation of the sheet metal burner, then the car's ignition performance in the start-up performance, humid environment [such as in the rain], fuel economy, it will be much more ideal. The throttle response will be more sensitive.
