MTC先生: 您好,我有一辆铃木GS125新车,冷车时一切正常,行驶8～10公里左右时,磁电机外壳处温度高(手只能摸上十几秒钟),离合器一边温度稍低。此时从怠速到2500转之间,发动机升速很不连惯,排气管发出“噗、噗”不连续的排气声,很容易熄火。2500转以上加速很正常。已修了近二年(断续修理),修理部也没办法,曾修过以下几个部位:1.怀疑混合比不好,曾调过油平面、油针高度;2.怀疑磁电机不好、点火不正常,曾换过磁电机内外转子及点火器;3.怀疑缸内爆震,开缸检 Mr. MTC: Hello, I have a new car Suzuki GS125, everything is normal when the car is cold, driving about 8 to 10 kilometers, the magnet housing temperature is high (the hand can only touch ten seconds), the clutch side slightly lower temperature . At this time from idle to 2500 rpm, the engine speed is not even used, the exhaust pipe issued a “puff, puff” discontinuous exhaust sound, it is easy to turn off. 2500 rpm acceleration is normal. Has been repaired for nearly two years (intermittent repair), repair department no way, had repaired the following parts: 1. suspected mixing ratio is not good, had transferred the oil plane, needle height; 2. suspected magneto bad , Ignition is not normal, had changed magnetic rotor inside and outside the rotor and igniter; 3 suspected cylinder detonation, open cylinder inspection
