GY6 Valve Springs (Inner, Pair)

GY6 Inner Valve Springs for 125-150cc Engines

This set includes a pair of inner valve springs made for GY6 125-150cc engines. They play a key role in how the exhaust and intake valves work, which directly affects engine performance. Among GY6 scooter parts, these are the ones to consider when low compression or ticking noises point to worn valve components. Before fitting them, confirm that your cylinder head matches your engine's specifications.

When to Replace It

Consider replacing valve springs if you notice signs such as weak engine compression or abnormal sounds coming from the cylinder head. Burnt valves or valves that no longer seal correctly mean the head needs to be serviced.
