| is total repaired. | | | | |
| | | | 4. Engine works flexibly |
| Chinese ATV or motorcycle's age is from 50 | | | | |
| thousand kilometers to 100 kilometers | | | | The major reason for engine's burst shake is |
| according to the way using motorcycle. | | | | fast gasoline burning. Burst shake generates |
| | | | powerful momentum and shake the cylinder |
| In that means, how to use motorcycle take | | | | result in cylinder abrasion. |
| great influence on motorcycle age. | | | | |
| | | | The reason for fast gasoline burning is |
| What is the sign for total repair? A | | | | following: |
| important sign is the piston and cylinder | | | | |
| abrasion. Cylinder abrasion is a key sign. | | | | Gasoline is not fit for engine's compression |
| When the cylinder abrases, space between | | | | ratio. According to motorcycle standard, high |
| piston and cylinder becomes bigger, and it | | | | compression ratio engine should use 93# |
| makes noises and leak. It makes fuel | | | | gasoline, and low compression ratio engine |
| consumption raise quickly, and drive | | | | use 90# gasoline. It will abrase cylinder if |
| inefficiency. It's time for total repair. | | | | high compression ratio engine uses 90# |
| | | | gasoline. |
| Total repair includes piston-cylinder space | | | | |
| adjusting and change the piston. Chinese | | | | Engine's rotate speed is between max torque |
| ATV's piston-cylinder space is about 0.05mm | | | | and max power. Chinese motorcycle is 3000r |
| to 0.07mm. The most important things is how | | | | min to 5000r/min. Every gear has it's speed |
| to avoid cylinder abrasion. | | | | range. If drives don't change gears in time |
| | | | and accelerate the motorcycle, it will make |
| Now we are discussing what to do for avoiding | | | | shaking noise in the cylinder. |
| cylinder abrasion. | | | | |
| | | | 5. Avoiding cylinder mucosity Cylinder |
| 1. A good warm-up for new motorcycle For | | | | mucosity is mucosity between piston and |
| example, when you buy a new 125cc motorcycle, | | | | cylinder. The reason for this are lacking of |
| though new motorcycle's piston and cylinder | | | | lubricant or lubricant doesn't work because |
| are lucent, but it's crude when taking a | | | | of engine's cool problem. How to avoid |
| carefully look. The crude part is easy hurt | | | | engine's over heat? On one hand, we always |
| when it's endured heavy power, and make | | | | clean heat disperser and make it better heat |
| cylinder been demaged. | | | | disperse function. On the other hand we |
| | | | should pay attention to disperser's |
| So when you are using new motorcycle, you | | | | temperature. |
| have to take a low speed until cylinder's | | | | |
| crude part is rubdown. You can extend the | | | | The normal temperature is under 180 degree, |
| cylinder age by this way which has been | | | | and we can check it by thermometer. Driver |
| proved by scientist. | | | | can also test the temperature by slobber. |
| | | | When the slobber makes the disperser noisy |
| When a new motorcycle is made, factory | | | | like zizi~~~, it means disperser's high |
| demands user take preparative drive which is | | | | temperature. We have to stop driving and cool |
| about 1 kilometer to 2 kilometers. During | | | | the motorcycle. Driving in a cool temperature |
| preparative drive, some factory installs | | | | can avoid cylinder mucosity. Furthermore, |
| items to limit driving speed. It's better not | | | | when you discover driving speed is falling |
| driving carrying another people. For the 2 | | | | after accelerating, you must stop driving |
| stroke motorcycle, gasoline lubricant ratio | | | | immediately. Because it's the auspice for |
| should be up to 20:1 which is the best ratio | | | | cylinder mucosity. After engine gets cool, we |
| for new motorcycle. | | | | should unload the piston and polish the |
| | | | piston surface adhere to cylinder by sand |
| 2. Cleaning air into cylinder | | | | paper. Only by this way we you save the |
| | | | cylinder, otherwise cylinder will broken. |
| If air coming through the air cleaner | | | | |
| includes some dust, it will enhance | | | | 6. Avoiding using motorcycle when it's cold. |
| cylinder's abrasion. So we must keep the | | | | |
| cylinder air very clean. Now Chinese | | | | Lubricant is frozed and it doesn't work in |
| motorcycle uses air cleaner, we should clean | | | | winter. Then we should warm up motorcycle. |
| the dust per 1000 kilometers. In the other | | | | The method is running the engine before |
| hand, we should always check the airproof of | | | | driving. Lubricant will work after warm-up. |
| the air cleaner avoiding air entering | | | | |
| cylinder directly. | | | | 7. Avoiding charcoal dropping into cylinder. |
| | | | |
| 3. Cylinder need good lubricant | | | | There is some charcoal on the top of piston |
| | | | and cylinder head. Charcoal will hurt |
| Liquid attrition is better than dry | | | | cylinder when it drops into the cylinder. In |
| attrition. To avoid the dry attrition, we | | | | order to reduce the charcoal, we have to use |
| should use lubricant to keep the cylinder and | | | | professional lubricant. |
| piston smooth in order to build liquid | | | | |
| attrition. It requires lubricant to be | | | | Driver also needs to clean charcoal on the |
| viscous. Lubricant's viscidity relates to | | | | piston, too much charcoal will make burning |
| temperature, we use different lubricant | | | | space smaller and increase the compression |
| according to different season. | | | | ratio result in burst shake. My friends, if |
| | | | you can do what I mention your motorcycle |
| Due to the international standard, summer | | | | will have a long age. |
