The company dynamic
A few days ago in the "motor home modification classroom" group of study to the motorcycle engine oil selection and maintenance of the problem, some hopes the guest officer greatly, that today in general first say the general classification of the motorcycle maintenance and maintenance matters needing attention.
The small white car owners who have just been exposed to big engines have a lot of knowledge about cars. In particular, the maintenance of the car, some can not find the way. This article hopes to help you. When you need to maintain it, turn it around to see if the problem is solved.
Large displacement motor itself part of the quality is very good, mechanical performance is very strong also, with armed to the teeth to describe is not too much, but also because of complex structure (125 completely both concept and domestic horizontal bar), so need more careful maintenance to long ride. Do not maintain the attitude of maintaining domestic 125, otherwise soon the car will be full of problems.
1. The oil
Machine oil this thing, is the first of maintenance, how to choose oil correctly. Can refer to: multi-cylinder, high speed, must use imported semi-synthetic oil above, with full synthetic imported oil. But don"t add those cowhide additives. The air - oil cooler requires more oil than the water - cooled car. And some single cylinder big displacement car, because crankshaft is used crankshaft bearing, to the machine oil requirement is relatively low, can use semi - synthetic, or SG grade of genuine oil.
Remember: oil is not oil. But synthetic oil can be replaced by a longer number of miles, and it"s a good deal. Pure synthetic generally 3000-4000 km, no waste, organic filter also, if your car is big trade trading, regular replacement of oil with the brand, so the engine should be very clean, without too much change oil filter, replacement of a machine in two oil filter. If you want to use 300V last time with 7100, the filter should be replaced together (because there will be residual oil in the filter, and different brands should not mix with different specifications).
2. The air filter
Air filtration is the lung of an athlete for a good car. Therefore, it is necessary to use clean air filtration. Imported cars are more expensive to filter, a few hundred, some car friends have heard so expensive, think, still do not change.
But this is no good, empty filter a damaged, dust, sand will all through the carburetor into the cylinder, efi too 】 【 wear ring and valve, if the congestion, can cause poor inlet, incomplete combustion, low efficiency of engine, power, fuel consumption increase. An increase in fuel consumption may lead to black smoke at high speed. After a long time, the gas door, the durability of the car, the power will be reduced. Especially in cities with poor air quality in the north, the air filters should be cleaned every few months.
3. The tire
For tyres, big engines do not want to buy used tyres or domestic ordinary ones. Used tyres used for a period of time, may also be placed for several years, the resulting rubber aging problem is very serious, this kind of tyre may pattern is quite deep, but the grip has fallen very much.
And those tires that are too shallow, or carved, are not to be considered. Now taobao so developed, also let a person in the family of lobbyists article yesterday say advertising taobao, I le a go, taobao but is a good god web station don"t need a big advertising) to buy new tyres imported tyres, a more than one thousand pieces, and your car is better than a small percentage is money, but the tire as a choice for motorcycle riding and ground contact, spent more money on the tire is very wise choice! It is also ok to make the tyres for the export of several large factories.
Daily tire maintenance: cleaning keep tread clean, do not plug the stone in the decorative pattern, it is important that the tyres can"t make water wax or oil, because oil has affinity to the rubber, will result in the crack of the tyre degradation, endanger the safety of their own, because the motorcycle is accomplished by pressure cornering, tire is an important part of the car.
4. The fuel tank
Domestic gasoline impurities are a lot. If you have time, take down the fuel tank once a year, remove the oil switch, drain the water below, and then drain the oil tank and reload it. The fuel tank is good for the machine.
5. Carburetor
In the same way, the carburetor will accumulate some impurities in it, and loosen the oil screw under the carburetor so that the impurities will flow away with the gasoline. If the carburetor oil must be timely maintenance and replacement, due to some car carburetor does not have good design, once the carburetor oil, gasoline can leak into the cylinder, if pushed, gas will leak into the cylinder, dilute the oil, if leakage of large amount of gasoline, you like to turn up again, so, your car is not far from hang is, this is why the basic carburetor common fault car call somebody else the cause of the garbage truck.
6. The battery
If you are on a regular ride, you don"t need to maintain the battery, but if you don"t ride your bike in the winter, remember to take the battery off and leave the car without power. If you don"t want to take it off, at least make sure you have a hot, hot car for a week or two, and make the circuit and the oil circuit work, and of course it"s better to get out of the car.
Tips: turn off the headlights before you hit the car. It is a great benefit to the battery.
7. The clutch
Even if a 250 engine car is enough to meet the daily speed, you can wring oil, as long as it is not red, the basic car is still in normal use. But if you have a bad habit of partially disengaging, the car will wear out. The record I have seen is that a man has completely finished the clutch of a 400CC sports car in the afternoon, and the fragments of the clutch have a great wear on the machine, so pay attention to this bad habit. In my opinion, it is a kind of open method to play 2 cars, but it is not suitable for high-power multi-cylinder cars.
8. Shock absorption
The pre-shock absorber is basically one year to replace the shock absorber oil, the shock absorber oil can be used in the car"s shock absorber oil, the effect is very good, one litre can be within 100 yuan. Also, the domestic oil seal quality is very good and durable. After shock absorption, if the oil is leaking, replace the oil seal when the core is not spent, but once the core is spent, only the assembly can be replaced.
9. The valve
This is odd. How do you maintain the valve? The answer is yes, the fuel additive that gas station sells, small bottle, red liquid, can add 40 litre gasoline. I have tried to add a CB400, and the former airway is brown. After using it, I disassemble the carburetor. The whole airway is silver-white. The light is new. General 1 year routine maintenance can. Of course, you don"t have to go to the gas station now. Where to? Taobao jingdong!
10. Spark plugs and ignition wires.
If you ride a domestic platoon, you will find that there will be a difficult starting point after the rain. How will that improve? If a little budget, investment of several modified high tension line and a set of iridium spark plug is necessary, including a lot of the guest officer used water trucks are used cars, so the high tension line leakage is common, there are many common?
Can you see if the high pressure line has hardened? In the long high pressure touching the part of the car, when the car is sending out a micro-arc? If so, then, this excuse, sometimes spending if you budget, a set of NGK, such as import high tension line that is little not, if you like price, then a set of domestic LiShuang line is enough. With the combination of the iridium fire nozzle, the ignition performance of the car in the startup performance, in the humid environment [like rain], the fuel economy, will also be much more ideal. The throttle response is also sensitive.
11. Tooth disk chain
I have observed a lot of roadside bikes, no matter the size of the engine, some of them with rust, some with dust on them, not so! Maintenance, generally speaking, there are the drops of oil, with butter, but, just very original, because these oils are easy to make the chain with soil dust, exacerbate wear and also splashing round box, very indecent.
The correct method is: spray chain oil. There are two kinds of chain oil, one is similar to ordinary oil, but it is more sticky. The other is like a white powder that doesn"t splash. Of course, the second is good. The chain oil only needs a thin layer, can maintain over 1000 kilometers, calculate also very cheap, and the shelf life is very long, do not need to consider storage problem. That way your car"s teething chain can take years to worry about.
12. The brake skin
The brake skin must be replaced as long as it is more than two thirds. Can"t wait until finished basic polishing grinding or all change, the first is safety, because the brake pads with of brake linings thermal soon passed to the substrate, easy to cause the brake friction material loss, "he said.
Second, is the wear of brake disc, as we all know, more than the carbon brake disc brake PiGui, to save expensive brake disc brake and loss and is not worth the cost, also, if there is an opportunity, can change the brake steel pipes, will enhance the safety, and improve the brake handle. Changing steel throat is a cost-effective brake.
Water 13.
Water cooled car, use the antifreeze solution of genuine article, one is water is not easy to go wrong, 2 is in the cold area air cylinder does not frost crack. If your car is the water in the tank is yellow, so will intensify cleaning waterways, concrete is, wash the water tank in the motor repair shop to buy a special kind of powder, add in the water tank, release the heat after the car, and so on clean, until clean, antifreeze and changing are factory.
The covers of the 14.
There is an underground garage and a private garage for good. If not, at least buy a hood and cover. Not only can you keep the vehicle clean, it is also good for the paint and body parts. Taobao is available. Jack ma: thank you wang for supporting our business so much...
15. Long-term storage
If you plan to keep your car for a long time, remember the following:
1. Clean the motorcycle first, dry or dry the motorcycle, and then apply oil or butter to prevent rust after washing, such as chain, adjusting bolts and bearings, etc.
2. Release gasoline from the fuel tank and seal it in containers. Otherwise, the "lightweight ingredients" in gasoline will be reduced (volatilizing into the atmosphere) for long periods of time, causing the motor cycle to start difficult or not to start. At the same time, the gasoline in the carburetor should be put out to prevent the impurities in the gasoline, such as the hole of the carburetor and the oil channel.
3. Remove the accumulator from the car and wipe it clean. Before the vehicle stops using, replenish the full power in the dry place and refill the battery once a month. But do not release the electrolyte in the battery to prevent the plate from being exposed to the air and cause the plate oxidation.
4. Four-stroke motorcycle should inject a certain amount of oil into the exhaust pipe. Remove the exhaust pipe from the car, add a small amount of oil from the front end of the exhaust pipe, then install the exhaust pipe, and then start the engine to evenly distribute the oil on the lining of the exhaust pipe to prevent rust.
5, remove the spark plug, from the mouth to the spark plug in the cylinder filling of around 20 ml dedicated four stroke motorcycle oil, pure mount spark plug, close the ignition lock switch (OFF position), stamped on the actuating lever 5-6 times, make the oil evenly distributed in the cylinder wall. If a motorcycle with no foot start can remove the spark plug, turn ON the ignition lock switch (ON position) and press the start button for 2-3 seconds.
6. Keep the standard air pressure on the front and rear tires. If the tire pressure is too low, the tire will prematurely age and cause a tear.
7. Finally, park the motorcycle in a dry and ventilated place, and pay attention to moisture-proof, so as not to rust. The motorcycle should not be parked in the open air for a long time, or it will accelerate the aging of the appearance of the motorcycle.
In the past, the big row cars were all under water, and now there are more and more domestic big platoon and big trade import cars, so the popularization of maintenance knowledge is becoming more and more important. I hope you can treat this steel partner well in your spare time, and treat it with your heart and heart, so that it can stand up when you need it.
Love your car, just like you love yourself.
