A silencer ring to suit the UMS 9-115cc — the nine-cylinder 115cc four-stroke radial from UMS.
On this engine the component is the silencer ring, which seals and locates the silencer at its joint.
Why this part matters: a failed ring is an exhaust leak that also lets the joint move and work loose.
Fitting note: Renew the ring whenever the silencer is removed and check the joint faces.
