What are the tips for motorcycle maintenance?
Motorcycle maintenance skills
Renewal and use of chain
Many people often replace the badly worn chain, but in fact, the chain only wears in one direction. A chain has four directions and can be used interchangeably. Just open the chain bolt, turn the chain around and reinstall it, and it will be as good as a new chain. When both sides of the inner ring are worn, the chain can be disassembled and turned over to turn the inner ring into an outer ring, so that the two brand-new faces can continue to be used. When all four sides of the chain are completely worn, it is not too late to replace them with new ones.
Clever cleaning of motorcycle carburetor
When the carburetor of motorcycle is in use, there is often sediment and water at the bottom of the carburetor, which affects the normal running of the vehicle. Here is a wonderful way to clean the carburetor without disassembly: first, turn off the oil switch, loosen the oil drain screw at the bottom of the carburetor with a screwdriver, and then turn on the oil switch after all the fuel in the carburetor is drained. After the oil flows out, continue to blow * * * or pump * * * to the waste oil discharge pipe on the outer wall of the throttle valve. At this point, mud, sand and water droplets will be found spouting from the oil drain pipe at the bottom of the oiler. Repeat this several times, and the sediment and water in the carburetor float can be cleaned. Then tighten the bottom screw, and the motorcycle can be used normally.
Skillfully remove oil tank rust
Motorcycle fuel tanks often rust. If it is not removed in time, it may block the oil circuit, but it is very troublesome to clean it up. You can find a slightly elastic stick about 30 cm long, fix a magnet at one end and put it in the bottom of the oil tank to paddle back and forth, and then take it out to clean the rust on the magnet. This can be repeated several times to remove rust.
Rust removal of electroplated parts
The electroplated parts on motorcycles will be corroded to varying degrees due to wear or rain erosion, which will not only affect the appearance, but also damage the parts. It can be removed by a rust removal method that does not corrode the coating. First, put ammonium acetate into the same amount of clean water, which is available in chemical stores, and heat it to about 70℃ after it is fully dissolved. Scrub the corroded parts with a soft cloth dipped in the solution until the rust spots disappear, and then wipe off the residual solution with a dry cloth, so that the electroplated parts are as bright as ever.
Self-made protective sleeve rubber pad
The side covers of many straddle-type motorcycles are inserted into the rubber pads on the mounting holes of the body through the arrow-shaped mounting posts on the inside of the covers to achieve the purpose of fixing. However, due to the frequent disassembly of the protective sleeve, it is easy to tear or lose the rubber pad, so this small part is not easy to match. The brief introduction is as follows: find a rubber stopper of an infusion bottle, drill a hole in the center of the rubber stopper with a tax collector such as a screwdriver according to the size of the installation column, and remove some rubber appropriately, so that the installation column can be inserted. Then insert the small end of the rubber plug inward into the mounting hole on the body. If the hole is small, cut the small end of the rubber in the longitudinal direction, and then install the protective cover. The infusion bottle stopper is very durable because of its good material, high elasticity and high strength.
103 magical use of glue
In the daily use of motorcycles, due to various reasons, the damage of some parts is inevitable. For example, falling or improper driving force may lead to the fracture of plastic and metal parts such as motorcycle lampshade and fender, and thread slipping is a common phenomenon. Using 103 high-strength fast two-in-one glue can quickly repair, saving money and effort. For example, when repairing the threaded slide seat, first clean the aluminium scrap and sludge in the slide seat hole, then evenly apply 103 glue on the inner wall of the hole and fix the cylinder head stud hole for 2 hours, and it can be used normally. Motorcycle fender. Plastic parts such as lampshades are damaged, so it is more convenient and practical to use 103 glue according to the instructions. However, the damage of important parts cannot be repaired in this way, and new parts should be replaced.
Misunderstanding of motorcycle maintenance
Misunderstanding 1: Misunderstanding of valve clearance adjustment. Speaking of valve clearance, we have to say what it can affect. Some people just want to be quiet when adjusting the valve. This is not right, and some people think that the valve clearance is a bit noisy and not serious. This is not good either. First of all, the valve clearance affects the ventilation of the whole engine and the afterburning period of the engine. * * * The afterburning period is the gasoline burning time after ignition. * * Then return oil after the valve is tightened. The answer is that the sound will be quiet, but the afterburner time will be shortened, the fuel consumption will increase, the cylinder temperature will rise, the engine will be prone to high fever and the idle speed will be unstable.
Then in one case, the valve clearance is too large, which will make the combustion period longer, the power of the car decrease, the sound becomes louder, and the high-speed valve is easy to fall off.
Myth 2: The understanding of gear and traction braking starts with the use of gear. Some people like to use engine traction braking very much, which is correct within a reasonable range, but it is incorrect in unreasonable gear, such as using 5 as normal driving speed and 4 as traction braking. Although the car will not have obvious setback, it is harmful to the engine. It is also necessary to use engine traction braking when going downhill, so don't use too low gear. That is, which gears to use when going uphill, which gears to use when going downhill and which gears to use when driving. This is a normal and standardized traction braking method.
Myth 3: misunderstanding of clutch. When it comes to clutch, you have to say gear. The service life of clutch is directly related to the use of gear. For example, some people like to start with 23 gears, which is very harmful to the clutch. Over time, the clutch will slip or burn. Especially in underbone, many people start with second gear, which is very bad. One kind of situation is semi-clutch, and sometimes it can't get up.
Myth 4: I don't know enough about tires, and I know very little about tire pressure. Many friends like extra-large tires and modify extra-large tires, which is not good. First of all, few people maintain cars for tire pressure and tire maintenance. Tire pressure affects braking distance, vehicle shock absorption, high-speed stability and cornering flexibility, which are all affected by tires. If your front tire pressure is insufficient and the tire pressure is too high, it is easy to puncture. As we all know, too high air pressure can easily lead to too high car sensitivity, shortened braking distance, high-speed drift and easy side slip when turning.
Myth 5: misunderstanding of brakes. No matter who or what car, many people like to use only the rear brake or the front brake, which is not good. It is suggested to develop the good habit of braking together before and after all the time, which not only doubles the safety factor, but also is good for braking. If you like to use the rear brakes, the rear brakes will age quickly, and the braking force of the whole car is on one brake and one wheel.
Myth 6: Maintenance of carburetor. The maintenance of carburetor is not only cleaning, but also adjusting. In winter, it is necessary to adjust the mixing ratio and oil needle height required for winter temperature, and in summer, it is necessary to adjust the mixing ratio in summer. Of course, don't clean the carburetor too much. Excessive cleaning of carburetor will cause the wear of carburetor air duct and increase fuel consumption. Remember to clean the air filter before adjusting and cleaning the carburetor.
Myth 7: the maintenance of shock absorption, many people, many bar friends, do not know that shock absorption oil should be changed. Of course, I think most car lovers should know that the damping oil should be replaced regularly and seasonally, otherwise, sludge will easily accumulate during damping, which will reduce the damping efficiency and increase the chance of oil leakage.
