How to clean the throttle?

The cleaning steps of the throttle valve are as follows: 1. First unplug the wiring harness plug next to the throttle, unscrew the fixing screw with a hexagon screwdriver, and then remove the throttle. 2. Cover the air inlet to prevent sundries from falling into the engine. 3. Spray the detergent on the dirt. Be careful not to spray the cleaning agent outside the throttle as much as possible, and don't slam the throttle inside hard to avoid damage to the throttle motor next to it. 4. finally, dry naturally. It is best not to wipe it with a rag, so it is easy to wipe off the lubricating coating on the surface. 5. After reinstalling the throttle valve, turn off the power supply and restart or re-match the throttle valve.
