Haojue DR 150 Idle at 9000 rpm and then cut off the oil. What happened?

This is probably caused by fire failure, and of course it may also be caused by abnormal oil supply. Specific analysis:

1, depending on whether it is EFI or carburetor. If it is EFI, it is not excluded that there is a problem with the throttle sensor or it is not installed or there is carbon deposition.

2. If it is a carburetor car, it may be caused by the unclean carburetor.

3, do not rule out the spark plug or high voltage package leakage.

4. Some motorcycles have double wheels or multiple wheels. If a single boss igniter is used, there will also be problems of normal idle speed and inability to refuel normally. In fact, this is a fire breakthrough.

5, the ignition angle is wrong, some have long bosses, and you will have this problem with the igniter with short bosses.

6. The engine has been repaired and the valve timing has not been adjusted.

7. The added oil has quality problems, such as water content.

8. The air filter is blocked.
