Motorcycle vehicles are something that has become an obligation for some motorcycle users. Need to understand one component in a motorcycle engine, one of which is a valve spring
The valve spring works automatically. very heavy and fatal because if there is a slight disruption it will be very fatal for each valve itself.
Example.
spring valves are not only useful for engine compression, but are also useful for opening and closing valves. If opening and closing the motorbike valve is not on time, the valve will press the piston at TDC or the top dead point and if the valve does not open and close on time, the motor power will not be perfect or weak.
