The decompression valve, also referred to as ‘deco’ or ‘deco valve’, vents compression in the cylinder for easier starting

The decompression valve temporarily reduces the compression in the combustion chamber during cranking and helps reduce the effort needed to pull the starter rope

It is opened manually and closes automatically as soon as the engine fires

It is a starting grip with a built-in shock absorber that helps reduce the effort when pulling on the starter cord

The forces which occur at the grip after the first compression stroke are smoothed out
