The solutions for a China IV EFI motorcycle failing to start are: 1. When turning on the key, if there is no self-test sound from the fuel injector, visually check if the fuse is blown and replace it if necessary. If there is a self-test sound, remove the fuel injector (keeping the connector connected), press the start button, and observe the fuel injection status, replacing the injector if needed. 2. Check the connection of the angle marker line and repair it. 3. Check the strength of the magneto signal, etc. The reasons why an EFI motorcycle may fail to start include: 1. Damage to the injection unit, no fuel injection, or a blown 5A fuse; 2. Poor contact of the angle marker signal sensor; 3. Weak magnetic field; 4. Battery failure; 5. Issues with the ignition system wiring; 6. Poor fuel flow; 7. Low-quality gasoline; 8. Engine failure.

What is a Manual Transmission?

Manual transmission is also known as 'shift transmission.' The manual gear lever acts as a shift fork, moving the sliding gears inside the gearbox to engage the corresponding gear, thereby meshing the driving and driven gears to transmit power and drive the vehicle. Hence, it is called 'shift transmission.' Its working principle involves shifting the gear lever to switch the driving gears on the countershaft, combining with the power output shaft through different gear sizes to alter the torque and speed of the driving wheels. Manual transmissions also include additional gears like 2 and 1 for starting or climbing slopes. When the clutch is depressed to shift into a new gear, the synchronizer aligns the speeds of the two gears to be meshed inside the transmission, ensuring smooth engagement. After releasing the clutch and easing off the accelerator, the engine speed naturally decreases accordingly.

How to Remove Cement Slurry from a Car?

Methods to remove cement slurry from a car include: 1. Before it hardens, wet and rinse it with clean water, then clean with a towel and cleaning solution. If the cement is not discovered and treated in time and has already solidified; 2. Use an acidic solution for cleaning, such as common white vinegar. White vinegar is an acidic liquid that can effectively dissolve cement. Pour white vinegar onto the cement attached to the car, wait a few minutes for the cement to soften; 3. Purchase a cement cleaning agent for cleaning or go to a car wash for professional cleaning. The advantages of cement slurry include good cementation, high stone strength, and convenient slurry preparation; the disadvantages are coarse particles, easy penetration into small pores, poor slurry stability, and the tendency to cement the grouting device if the grouting time is too long, making it difficult to remove.
