What is the solution that the engine cannot start after putting the motorcycle aside for a long time?

The solution that the engine cannot start after putting the motorcycle aside for a long time is:

1.Turn off the fuel switch, find the oil release screw on the carburetor, remove the deteriorated gasoline inside, tighten the screw and open the fuel switch;

2.Remove the spark plug, use the syringe to add about 5 ml of gasoline or oil to the cylinder, and install the spark plug to restart.

The reasons why the motorcycle can not fire for a long time are:

1.The gasoline inside the carburetor volatilize or deteriorate, the gasoline into the cylinder can not burn normally, so it can not start;

2. The oil on the piston ring into the oil pan, resulting in the sealing performance of the piston ring decreased, the cylinder pressure is insufficient, leading to the failure to start.
