UMS 5-260cc SENSOR LOCK SCREW ( X 10 QTY / Pack)

Replacement sensor lock screw for the UMS 5-260cc, the five-cylinder 260cc four-stroke radial from UMS.

Function: it is the sensor locking screws that hold the pickup in position.

The reason this ends up on an order: a screw that backs out lets the sensor move and the timing drift, so these are replaced at service. Supplied as a pack of 10, which is how these small parts are normally bought — you rarely need just one.

Fitting note: Use the correct torque and check the air gap afterwards.
