My motorcycle is a Haojue Neptune scooter. It is summer now, and the weather is not cold. The problem is that when I get up in the morning and start it, the engine and gearbox are both turning.

Let's talk about the starting point first. Normal cold start, no need to fill the throttle. The carburetor has an electronically controlled throttle, which is automatically controlled and will automatically increase the oil intake. After starting, the rotation speed is often high, and it will automatically return to the normal idle state in a short time. First, you should check whether the electronic throttle valve is working normally. You can't rule out the problem that the valve seal is not tight when the car is cold, and then talk about the rear wheel rotation. After starting, the machine can run normally, and it can be pressed when it is idle.
