100 how to disassemble the motorcycle intake valve? The valve leaks, and I want to replace it myself, but I can't get out two springs, one thick and one thin. What should I do? Excuse me, steps and methods This spring is a valve return spring, and its two rotation directions are opposite to suppress the vibration of * * * *. If there is no special tool, you can remove it with two sleeve heads: one under the valve head and the other on the pressure plate of the lock plate, and then knock it with a hammer, so that the lock plate (two) can be shaken off, and the spring and the valve can be removed calmly. The new valve needs to be ground with the valve seat. It is best to replace the valve oil seal with a new one during assembly, otherwise the oil will escape into the combustion chamber. Please grind it carefully.

Hehe, I hope it helps you.
