Why does the motorcycle turn off as soon as the throttle is released after starting?

1, releasing the throttle will turn off the engine, indicating that the idle speed is unstable or too low! If it is too low to solve, just adjust it! But if it is unstable, it will be a bit troublesome.

2. If the vehicle doesn't start for a long time, the gasoline will cause gum blockage on the inner wall of carburetor and metering hole, so give up the old gasoline and start the test run again.

Other reasons:

Gasoline: The weather is cold, and the oil temperature of gasoline drops very low. This kind of gasoline is not easy to vaporize in the cold carburetor, which makes the gasoline content in the mixture too small.

If it is just a crash, there will be no problem of refueling and flameout after normal use. At that time, there were symptoms of refueling and flameout because the carburetor leaked gasoline.

Extended data:

Solution:

Clean or replace the carburetor.

2. Check the wear degree of the valve ejector pin and rocker arm, adjust the clearance, and replace the worn parts if necessary!
