101 OCTANE GY6 50cc Throttle Holder

The 101 OCTANE GY6 50cc rocker arm is an essential component for the proper functioning of Chinese 4-stroke 139QMB and QMA 50cc engines.

This complete rocker arm assembly comes with rocker arms, shafts, and a valve regulator, designed to ensure optimal performance and increased reliability.

Replacing the entire assembly rather than repairing individual parts allows for a more effective approach to addressing any defects, as often a greater number of components are compromised than initially apparent.

Additionally, this choice significantly reduces the time and effort required for installation.

It is important to note that, in some situations, the length of the piston may not be sufficient to reach the valves.

In such cases, it is advisable to use the piston spacers under the lever, taking into account the variations between different cylinder heads.
