Honda Jiayu 1 10 has driven 40,000 kilometers, but it can't get on at 70 yards.

The specific reasons and methods are as follows:

You can clean the throttle first, which is generally caused by insufficient throttle opening data.

If it doesn't work after cleaning, you need to read the engine data stream.

See if the intake pressure can reach above 170 bar at idle speed, and then continue to accelerate. See if it will rise above 350 bar. If there is no change, it means that there is air leakage in the straight pipe recently.

If it is a motorcycle, it is also the dirty intake valve that leads to insufficient intake opening data.
