• What to do if the engine is out of cylinder and the temperature is uneven?

    It is recommended to replace or clean the spark plugs, and if conditions permit, remove the carburetor to adjust the mixture concentration. For cars that frequently run out of cylinders, it is recommended to make a self-made spark plug sleeve as a backup.

  • What should I do if the whole car suddenly loses power?

    Suggest opening the fuse box on the edge cover, as it is possible that the fuse has burned out. Check and replace the fuse.

  • What should I do if I vomit when riding a bike at low speed and revving normally from one to four thousand revolutions per hour?

    Suggest replacing the spark plug. Oil resistance is caused by a spark plug malfunction, edge sparking, and misfire. Many people think it's a problem with the air filter and igniter, but in fact, these two rarely have problems.

  • Suddenly unable to refuel while driving, then slowly stalling, stopping for a while before starting again, and then unable to start again

    Suggest checking if there is a gasoline filter installed, as it may cause poor oil discharge and is best removed.

  • Power supply issue, the car won't start the next day and often runs out of battery. What's going on?

    Suggest checking if you have ever modified a 100 watt lamp. If you have replaced a 100 watt lamp, it will consume a lot of electricity. (Xenon lamps do not consume electricity.) When turning on the lamp for a long time at night and parking, turn off the lamp, coax the accelerator, and then turn off the engine.

  • What's wrong with the chain making a noise?

    It is recommended that if the noise is regular, rotating the rear wheel chain in neutral will cause the chain to stretch and deform, and the abnormal noise will disappear after replacing the chain. If it still makes an outrageous noise after replacement, it is a problem with Xiaofei, and if it is severe, it will also make a loud noise.
