摩托车在维修过程中,常忽视许多小问题,如:1)更换活塞时,容易忽视活塞销孔中心到活塞顶的高度尺寸(俗称活塞压缩高度),其尺寸的变化,可能引起发动机燃烧室压缩比的变化。压缩比变小,发动机动力下降,
Motorcycle repair process, often overlooked many small problems, such as: 1) When replacing the piston, easy to ignore the piston pin hole center to the height of the piston top size (commonly known as the piston compression height), the size of the change may cause the engine combustion chamber Compression ratio changes. Compression ratio becomes smaller, the engine power down,
