| What is the sign for total repair? A important sign | | | | According to motorcycle standard, high |
| is the piston and cylinder abrasion. Cylinder | | | | compression ratio engine should use 93# gasoline, |
| abrasion is a key sign. When the cylinder abrases, | | | | and low compression ratio engine use 90# |

| Now we are discussing what to do for avoiding | | | | mucosity between piston and cylinder. The reason |
| cylinder abrasion. | | | | for this are lacking of lubricant or lubricant doesn't |
| 1. A good warm-up for new motorcycle For | | | | work because of engine's cool problem. How to |
| example, when you buy a new 125cc motorcycle, | | | | avoid engine's over heat? On one hand, we |
| though new motorcycle's piston and cylinder are | | | | always clean heat disperser and make it better |
| lucent, but it's crude when taking a carefully look. | | | | heat disperse function. On the other hand we |
| The crude part is easy hurt when it's endured | | | | should pay attention to disperser's temperature. |
| heavy power, and make cylinder been demaged. | | | | The normal temperature is under 180 degree, and |
| So when you are using new motorcycle, you | | | | we can check it by thermometer. Driver can also |
| have to take a low speed until cylinder's crude | | | | test the temperature by slobber. When the |
| part is rubdown. You can extend the cylinder age | | | | slobber makes the disperser noisy like zizi~~~, it |
| by this way which has been proved by scientist. | | | | means disperser's high temperature. We have to |
| When a new motorcycle is made, factory | | | | stop driving and cool the motorcycle. Driving in a |

| preparative drive, some factory installs items to | | | | falling after accelerating, you must stop driving |

| must keep the cylinder air very clean. Now | | | | Lubricant is frozed and it doesn't work in winter. |
| Chinese motorcycle uses air cleaner, we should | | | | Then we should warm up motorcycle. The |

| 3. Cylinder need good lubricant | | | | There is some charcoal on the top of piston and |
| Liquid attrition is better than dry attrition. To avoid | | | | cylinder head. Charcoal will hurt cylinder when it |
| the dry attrition, we should use lubricant to keep | | | | drops into the cylinder. In order to reduce the |

| liquid attrition. It requires lubricant to be viscous. | | | | Driver also needs to clean charcoal on the piston, |
| Lubricant's viscidity relates to temperature, we | | | | too much charcoal will make burning space smaller |
| use different lubricant according to different | | | | and increase the compression ratio result in burst |

| Due to the international standard, summer | | | | your motorcycle will have a long age. |
