Complete cylinder head for the 50cc 139QMB / QMA engine. In contrast to many offered cylinder heads this is delivered completely. This means valves, valve springs, valve stem seals etc. are completely pre-assembled. The cylinder head is therefore built-in and the exchange and grinding-in of the valves in connection with the required special tool is no longer necessary.
The head is supplied with a connection for the secondary air system [SLS].
The scope of supply does not include toggle link and camshaft. Delivery is as shown.
ATTENTION: It is possible to pass through different rocker arms, the length of the plunger is not sufficient to reach the valves. In this case, the lock nuts of the tappets must be moved under the lever. This is due to different cylinder heads and can occur with changing vehicles.
